QuestionBrake Pedal Vibrates on Stops:  I have a 2000 Chevy 4X4 truck and when I come to a stop the brake pedal goes down and vibrates. I have almost hit the car in front of me on a couple of occasions. The ABS light is not on but it seems like it is in the Anti Lock Brakes, can you please help me.
AnswerThis is most likely caused by rust build up under the front wheel speed sensors, but can be other things like a bad wheel speed sensor or wheel bearing. The front wheel speed sensors can be cleaned in most cases but sometimes they are rusted in and break when trying to remove them. You can get just the speed sensor without the bearing but if the wheel bearing is loose or making noise it comes with the speed sensor so you should just buy the whole assembly and replace it all. To find out for sure if it is the rust build up or other problem you will need a lab scope, but rust is the most common cause and just takes time to clean if the sensors come out OK. We fix a lot of them here at the shop with just the cleaning.

QuestionHot Engine Shuts Off:  When my engine is cold my car is working fine, but after is gets hot it shuts off. Please help!
AnswerThis sounds like an electrical part that it going bad like a fuel pump or crankshaft sensor, but could be other things as well. A problem like this usually takes some specialty equipment to find, such as a lab scope, fuel pressure gauge, spark tester, or noid light. This may be one that you want to take in to a repair shop since the tools to diagnose the problem and the parts that could be causing the problem are expensive.

QuestionSelecting a Repair Shop:  What should I be looking for when I am selecting an auto repair shop?
AnswerFirst you should ask your friends and neighbors for some places that they have had good service from. Next try going to the repair shop and introduce yourself as a possible customer and ask what type of vehicles they work on. See if the mechanics are comfortable with your particular car make and model. Some shops specialize in certain car makes like GM, Ford, or Chrysler and some do all US made. Most shops can handle steering, brakes, and suspension on any car make. When it comes to drive train problems on foreign models you want to know that they have the proper tools and know how before they work on your car because if things go wrong it can get very expensive. Also, look around the shop when visiting and make sure they have the proper facility license and repair shop signs on the wall. Make sure they have current mechanics certifications in the areas you plan to have worked on like brakes, engine, transmission, tune-up, engine performance, and so on.

QuestionTiming Belt:  I called for a price to replace my timing belt and the price from one shop to another was very far apart (like over $200). When I asked the shop I called last why so much more they said that the other shop may not be doing as complete of a job as them. The shop manager explained that when doing a timing belt even for maintenance that you should use a complete kit with pulley's, tensioner, and a water pump where applicable. I called back the first shop and they said I did not need to do all that other stuff unless I need it or had the extra money to spend anyway. What should I do?
AnswerWell I have been in this situation more than one time and have found that when you have something so important to your engine it is always better to do the most complete job you can afford. Some engines will damage the valves if the timing belt goes bad and then it gets very expensive. The timing belt has several pulleys it goes around and sometimes drives the water pump as well. If any of these pulleys go bad the timing belt goes with it (every time) so I always recommend replacing them when possible. The water pump is the same as a pulley but it can also leak coolant as it ages even if the pulley is still turning. It would need to be replaced and may require removing the timing belt to be replaced so installing a new one when doing the belt could save you a lot of extra labor down the road.

QuestionStarter Jump:  Lately, I have to jump my starter to start my car. What could be the problem?
AnswerThis could be a few different things. First you should have your battery tested. Next would be a charging system test and current draw test to see if something is discharging your battery when the car is turned off. Also, you should test the starter draw to make sure it is not taking too many amps to turn the car over. A few things you could look at yourself is to make sure that no lights in the car are left on (glove box and trunk lights can be a little tricky at times). Make sure your battery cable connections are clean and tight, if there is a lot of corrosion on them try pouring a mixture of baking soda and water over them first to clean them. Use a wire brush to finish but be careful, battery fluids are very corrosive and can remove paint and burn skin so wear gloves and safety glasses when working around the battery.

QuestionFuel & Stabilizer Bar:  When my fuel tank is about a 1/4 full or less I have a lot of trouble starting my car. Sometimes it won't even start until I put gas in it. I recently purchased this car and I am hoping I did not make a big mistake. Also the stabilizer bar is broken. Can the piece be welded on or do I have to have the whole piece replaced. If so what would the cost be? Thank you, Judy from Holly Mi
AnswerJudy, this could indicate a problem with your fuel level sending unit not reading correctly. The only way to tell this is to drop the tank and compare how much fuel is in the tank to how much the gauge reads. The other problem could be a failing fuel pump. It may draw air in when the level gets too low causing this problem. The sender and pump can be serviced separately but if you end up replacing the pump it comes with the sender automatically on this car.

As for the stabilizer bar I would need your Vin # to give you the correct price as there are two different ones offered for this vehicle and the price is about $60.00 apart. The cost would most likely be between $260.00 and $320.00.
Back

QuestionAir Filter:  I recently got an oil change and the technician suggested that I change the air filter on my car. How important is it that I change my air filter? How often should I do it?
AnswerThe air filter in your car should be checked at every oil change. Most will last at least 30,000 miles but if you live or travel on dirt roads often then you will need to replace your air filter at lower mileage intervals. The air filter is very important to fuel mileage and engine life. It is also very important to use a quality air filter in today's vehicles because cheaper air filters tend to let particles come off and get on the mass air sensor in cars that are equipped with one. This can cause problems such as a hesitation on acceleration and poor fuel mileage.
Back

QuestionAC Odor:  When I turn on the air conditioning it emits this musky, funky odor. I've heard it could be mildew built up in the AC compressor. What can I do about this problem?
AnswerThis is most likely a cabin air filter or evaporator with a possible drain issue in the heater case. There are some chemicals available for this problem at most auto parts stores. To locate your cabin air filter look in your owners manual or check with your local repair shop and they will be able to help you find the location. Not all cars have cabin air filters but most newer vehicles do. If the heater case drain is plugged or restricted you will most likely need a hoist for this as they are in very difficult locations most times.
Back

QuestionBrake Pads:  When I go to the parts store to buy brake pads for my car there are several different types available. How do I know what pads to put on my car as the price varies so much for the different pads?
AnswerThe different types of brake pads available for most cars today are ceramic, semi-metallic, and organic. Most newer cars and light trucks come with ceramic pads. As far as what to use depends on your driving and preference. Ceramic are the most popular since they provide good stopping, produce very little if any brake dust, and do not tend to squeal at times like semi metallic pads do. However, they do wear your rotors more than semi metallic or organic and I find that the rotors tend to warp more with ceramic pads. Semi metallic pads are my personal preference and for most drivers these are adequate and will last almost as long as ceramic pads. Organic pads are a thing of the past these days but are still available in some cases. They tend to wear out fast but take very little brake pedal pressure to stop. Organic pads do not wear the rotors nearly as fast. Always make sure when replacing brakes to clean and lube the slides/pins and replace the hardware for the best braking performance.
Back

QuestionABS & Traction Control:  My traction control and ABS lights are on but my car drives and stops fine. What could be the problem and will it hurt to keep driving my car this way?
AnswerThis could be caused by a few different things. One being a wheel speed sensor or wiring, vehicle speed sensor, blown fuse, or bad relay. Last, but not the least expensive by any means, is a bad ABS control module or hydraulic pump. In most cases this will not affect normal driving and will only be noticed if you have to stop fast on wet or icy roads, then the ABS will not operate. The traction control actually applies the brake if you are stuck or one wheel has less traction than the other, helping you to get torque to the wheel with the most traction. Letting this go usually will not make the problem worse but other problems can arise. This could make it more difficult to diagnose as you may have to fix the first problem to find anything else that may have gone bad since the original symptom.
Back

QuestionKnocking Noises:  I hear a lot of knocking noises when driving and only when car is in motion, especially on take off and turning.
AnswerThis is a hard question to answer without more information, but I will give you as many possibilities as I can. In a front wheel drive car this could be caused by C/V joint, wheel bearing, sway bar links, bushings, control arm bushings, worn brake caliper pins or brackets, motor mounts, ball joints, tie rod ends, or a loose wheel. In a rear or four wheel drive vehicle this could be caused by many of the above but also could be a bad u-joint, front or rear differential, or transfer case. At any rate this should not be taken lightly and should be looked at right away since most of these could be safety issues and could cause you to lose control of your car.
Back

QuestionBrakes Chirping:  My car is making a chirping noise when I hit the brakes. Does this mean that I need to replace my brakes?
AnswerThis could mean that your brake pads are getting low and need to be replaced. In some cases metallic brakes will make a slight squeal or chirp noise while coming to a stop. Either way you should look at your brakes or have them inspected at a qualified repair shop since this is always a safety issue. If a car does not move it is not always a safety issue but there is only one reason to use your brakes and if they do not work you and the person in the car in front of you might wish you would have had them checked!
Back

QuestionAlternator Bad?:  I think that my alternator might be going bad. Is there anything I can do to check for sure if that is the problem?
AnswerOne thing that you can do to check the alternator is if you have a volt meter you can test the battery voltage before you start the car, then again while it is running. The voltage should be above 12 volts not running then go up to 14 volts while running, but not over 15 volts. If the voltage does not go up or gets lower after starting this would indicate an alternator that is not charging. This does not always mean that the alternator is bad though. You would still need to check the wiring to the alternator to make sure it has the proper powers and grounds. On most newer vehicles the computer controls the alternator and a lab scope is needed to check the proper signal to turn the alternator on and off. If you do not have access to a wiring diagram or lab scope you should take the car to a qualified repair shop. If the alternator is easy enough to remove and install most parts stores have a bench tester and will test the alternator for you before selling you the new or remanufactured one.
Back

QuestionCaliper Sticking:  My front caliper is sticking. What can I do to fix this? Will this cause other problems?
AnswerThis could be caused by a few things. One is a bad brake caliper. If this is the problem I recommend replacing both sides to keep your car from pulling or wearing the brake pads more on one side than the other due to one caliper working more freely than the other. The other possibility is sticking brake hardware or slides that can easily be fixed with proper cleaning, lubricating, or replacement. One more thing that can cause this is a brake hose that is damaged on the inside. This is sometimes the hardest problem to diagnose, not the most common, but should not be overlooked. As far as if this can cause other problems the answer is yes. Over time it can cause your rotor to warp and also overheat the wheel bearings causing them to fail prematurely.

QuestionATC Fuse Blows:  I have a 2000 old's Bravada, 4.3 liter engine all-wheel drive. When I put it in gear the 20 amp ATC fuse blows. (Active Transfer Case) I can't find the cause. Any suggestions or estimate to fix this?
AnswerThese systems seem to have a lot of problems with the encoder motors going bad but a few with wiring problems. I have included a test to determine which one it may be. If you would like to bring it by the shop we could check it for you and give you an estimate for repairs. We are located in downtown Holly across from the Holly Doughnut Shop. Our address is 402 N. Saginaw. Thanks for the question and I hope this helps.

1. Disconnect the encoder motor Red and Black wire connector and install a test light across the 2 terminals.
2. Test drive the vehicle and verify the fuse does not blow. If the fuse continues to blow, check for short to ground in the wiring between the Transfer Case Control Module and the encoder motor.
3. If the fuse does not blow, replace the encoder motor.
4. Check for incorrect size circumference tires causing premature motor failures. Chalk each tire at the 6 o' clock position, drive the vehicle 10 tire revolutions. Verify all tire chalk marks are equal. If the chalk marks do not line up replace the affected tire and recheck.

QuestionStalls While Driving:  When I'm driving down the road my car stalls out, but it starts up when I restart it with no problem. What can be wrong?
AnswerThere are several possible causes for this type of problem, such as vacuum leak, bad idle speed motor, torque converter solenoid, crank or cam sensor, and many more sensors that can cause this. First I would need to know if it stalls while moving or only at stops? Then you would need a scan tool to watch the live data for any possible problems that the computer monitors and after that it may get more technical requiring a lab scope.
Back

QuestionClutch Wear Syptoms:  I have a 2006 Honda Civic, 5 speed manual transmission, with 85,000 miles. How can I tell when the clutch is beginning to wear and might need adjustment or service? What are the symptoms and how much will this cost me? Thanks, Joe in Argentine, MI.
AnswerJoe - This system has a hydraulic clutch and there is no adjustment. There is a fluid reservoir like the one for your master cylinder for the brakes and usually takes brake fluid to fill, but you should always check your owner’s manual BEFORE adding fluids to your car. To tell when your clutch is getting worn the first sign is that when you give the car gas while going up a hill or taking off from a light if the engine rpm goes up but the car does not seem to speed up with the engine speed then the clutch is most likely slipping. Other signs are if the clutch pedal does not seem to engage until your foot is very high off the floor or too close to the floor. One more thing to feel for is when you let up on the clutch if the car seems to jump forward or shutter and then smooth out when the pedal is fully released. This could mean there are hot spots on the flywheel or pressure plate. The cost of this job is approximately $1,260 and this includes a new clutch disc, pressure plate, pilot bearing/bushing, release bearing, and resurfacing of the flywheel which should always be done with this job.
Back

QuestionShocks & Struts:  How do I know if my car needs shocks or struts?
AnswerOriginal equipment manufacturers suggest a replacement interval of 50,000 miles for their shocks and struts, however, there are a few simple ways to determine the condition for yours specifically. The easiest shock defect to diagnose is one that leaks oil from the cylinder. A leaking shock is a ‘bad’ shock every time, but a shock that is not leaking is not necessarily a ‘good’ shock. At 5 mph, smoothly turn the steering wheel from side to side and take note of how severely the vehicle rolls back and forth. Next, brake sharply (again at 5 mph) to see if the nose of the vehicle dives significantly. From a standstill, accelerate moderately to see how much the rear dives and the nose rises. Finally, inspect the rubber “travel limiting bumpers” usually located on the chassis directly above the shock or strut. Marks on these bumpers indicate excessive travel and would be a definite sign of a worn suspension.

Thanks Galon from Holly Automotive (CARQUEST) for answering this question, having completed the KYB suspension course. We value his input on this topic.

QuestionDiagnosis Missed/Inaccurate:  I recently had car trouble & towed my vehicle to a repair shop. They diagnosed a major repair & gave me an estimate for the repair of a couple thousand dollars. Although the car was old I decided to fix it. After the repair the car was still not drivable and had to be towed to another repair shop, and was eventually diagnosed with another major repair, pushing the repair cost with the additional amount over what the car was worth. I was out my car, plus had to pay for a major repair. Is there any recourse for a missed/inaccurate diagnosis, after you’ve paid the bill? Or was there anything I could’ve done to avoid paying the bill in the first place?
AnswerThe first advice in this situation is to ask the service manager or mechanic if this will fix what you brought the car in for and if there is any chance that there may be other problems. Then always (ALWAYS) ask to see the old parts or have them back. The shop has to keep these parts BY LAW for three days even if you do not request them back. Once you have decided to have the repair work done and if a problem arises ask to see the manager or owner. If you are not satisfied with the results then the next step is to document every detail, so that nothing is left to chance, and call the MICHIGAN DEPARTMENT OF STATE at 1-888-767-6424. This number should be posted on the repair shops waiting room or office wall. The State of Michigan will get involved and contact the shop for you. If they are not able to resolve it with the shop owner they may ask you to take the vehicle to a service center the state chooses and have the repairs evaluated, then decide what the outcome should be.

QuestionDifferential Bad - Front (SUV):  I just had the front end differential in my 2002 Trailblazer go bad. I was told the bolt was loose and the oil drained out. How major of a repair is this and what could cause the end to be loosened, when I haven’t had any service done to it? Thanks, Denise of Fenton, MI.
AnswerDenise, these types of trucks have a high failure rate with front differential problems. Usually it starts with not being able to engage the front axle due to a shift motor problem, but there are a number of complaints with this type of four wheel drive system in general. As for the loose bolt it may be from vibration or just never properly installed and it took this long to get loose enough to cause a problem. One other thing you may want to do on this vehicle is to have the transfer case fluid changed as it too has been known to cause some problems. The fluid is expensive but much less than the repairs and can only be bought at a GM dealer as far as I know.
Back

QuestionTune Ups:  How often should I get a tune-up on my car?
AnswerThis varies from one vehicle to the next with most of todays newer cars having 100,000 mile spark plugs in them. It is best to read your owners manual but other items included in your maintenance should be checked or replaced much sooner! Some examples are fuel filter, air filter, serpentine belt, pcv valve, and cabin air filter. Most of these items should need replacement at around 30,000 miles.
Back

QuestionParking on Incline in Cold Temps:  When parking on an incline in cold temps overnight, should the engine face uphill or downhill for a cold morning start?
AnswerThe answer to this is uphill so that your motor oil is toward the pick-up screen or sump for the oil pump. Also it is best to face the car away from the wind or park it with the front end close to a building or structure to block the wind from the engine as much as possible.
Back

QuestionSerpentine Belt:  How do I know when to replace my serpentine belt?
AnswerThe best way to tell is when you look at the belt if there are several small cracks on the groove side. This is the best indicator but some belts will get loaded with debris also and begin making noise which is another reason to replace the belt. One more thing to always check when looking at your belt is the tensioner assembly. It should spring back smoothly and not have a large gap where it pivots.
Back

QuestionAlignment - Recurring Problems:  I have a 2008 Chevy Impala and my alignment keeps going out every couple of months. The dealer says that it’s because I live on a dirt road. I rarely ever go over 20mph down my road because of the bumps. Is there anything else that could cause my car to be going out of alignment so often?
AnswerThis is a hard question to answer because I am not sure of what is actually off when they re-align your car. I talked to some friends at Holly Tire and Auto and they had some good input. Ben mentioned possible loose cradle bolts and this made a lot of sense to me. Alan said he would like to try to help as well. The next time you need an alignment bring it to him and he would be able to put it on their alignment machine and see exactly what is out of spec. Hopefully they can find the answer. They have had years of experience with this and they do our alignments as well. We do not see this happen with as many customers living on dirt roads, even with older cars, and we hope not to.
Back

QuestionBack Firing:  I’m experiencing problems with my engine back firing. What could be wrong?
AnswerThe most common cause for this is ignition related failures, such as plugs, wires, ignition coil, distributor cap or rotor. But this could also be caused by not enough fuel (running lean), vacuum leak, ignition timing, or a faulty sensor.
Back

QuestionHeater Not Working:  I have a ‘97 Ford Taurus and the heater is not working, although the fan comes on and it blows out cold air. I replaced the thermostat, still the same problem. It doesn’t overheat and the air works fine. Any suggestions on what to check or replace? Louise of Holly, Mi
AnswerLouise, I suspect a plugged heater core on your car. There is a simple way to check for this if your heater hoses are easy to get to near the outside of the dash. Run the car to operating temp and feel both heater hoses. If one is hot and the other is cool or just luke warm then the heater core is most likely restricted and may be able to be flushed out. Other possibilities are heater control valve or blend door.
Back

QuestionFuel Types/Octane:  I travel mostly city roads, with a lot of stop and go. Does it matter which type of gas I use for my car?
AnswerI personally use the lowest cost fuel I can but some auto makers have specific octane ratings they recommend you put in your car and some even recommend the lower octane fuel for certain models, the best advice is to always follow the manufacturer’s recommendation and if you hear a pinging or spark knock sound when you accelerate try going up to the next higher grade fuel to see if it helps.
Back

QuestionWinterize:  What are your suggestions for getting my vehicle ready for this winter?
AnswerI recommend having your coolant tested for strength, your belts and hoses as well as all fluids checked for proper level, you should also have your tire tread depth checked and tire pressures adjusted. Check our web site and coupon ads for our free winter inspection coupon available this month. P.S. Don't forget to turn on your heater and rear defroster now to make sure they are working properly before it gets too cold and you really need them.
Back

QuestionTransmission Flush:  How often should I flush out the automatic transmission fluid in my car?
AnswerThe answer to this is to follow your manufacturers recommended interval and your driving habits. If you do a lot of hauling, towing, or plowing snow you should do this more often than recommended by the manufacturer. Most vehicles are 48,000 miles but some are more. I personally recommend 48,000 miles myself.

QuestionStarting Problems:  James in Holly, MI Asks - 90 Lumina car 3.1 not starting, coughs, new fuel pump, fuel regulator, ignition module, crank sensor, throttle position sensor, acts like no fuel, inlet 72psi, out 47psi, within spec. Any ideas?
AnswerJames, I have seen a lot of these cars with one or two bad fuel injectors that have low resistance cause a problem like yours. The way to test them is with an ohm meter. The resistance on all injectors should all be about 11.8 to 12.6 ohms. If any are very low this will cause a problem since they are bank fired (meaning there are three on the same circuit that pulse at the same time). Any one being bad will stop all three from working. As for your fuel pressure it should be 40.5 to 47.0 psi with key on and engine off and drop 3.0 to 10.0 less when you start the car. P.S Try to unplug the injector right next to the oil fill cap since it is the only one you can get to without lifting the upper intake. Then try to start the engine and if it starts then you have at least one bad injector, not necessarily the one you unplugged though. Please respond and let me know what you find out. chris@wilkinsonautorepair.com
Back

QuestionShifting Hard:  When my car warms up it shifts hard. What could be wrong?
AnswerThis could indicate a transmission problem and should be checked as soon as possible. There are other things that may be the cause as well such as throttle position sensor and coolant temp sensor not working properly. This is definitely something you do not want to let go for too long as it could get very expensive if the transmission completely fails.
Back

QuestionHills - Power Loss:  My car drives along smoothly at 55 mph on level ground but as soon as I start to take it up a hill it cuts back to around 35 mph. I can even get a running start at 65 mph, but the car does the same thing, it bogs down on the uphill incline. What could be the problem?
AnswerThe possible causes are plugged/dirty fuel filter, weak fuel pump, faulty map or mass air sensor, transmission slipping, restricted exhaust or faulty ignition component such as plugs, wires distributor cap or rotor, restricted/dirty air filter and last but not cheapest is a timing belt or chain off by a notch or two. All of these are easily checked as well as a few more possibility’s by a qualified repair shop or mechanic with the proper tools and knowledge.
Back

QuestionEngine Stutter:  I have a stick shift, since the weather has become warmer my engine has been stuttering like it has the hiccups. Why is it doing that?
AnswerI would need to know if this is happening when you let the clutch out to pull away from a light or if it is at idle or driving down the road. If it is while pulling away from a stop, then it may be hot spots on your flywheel. You would have to have it resurfaced or replaced and a new clutch, pressure plate and release bearing installed. If it occurs while driving, it may be an engine misfire and would be more pronounced going up a hill or incline in the road.
Back

QuestionStalls When Idling:  I have a problem keeping my engine running when it is idling, it keeps stalling out. What can I do?
AnswerWell depending on if your car is older and carburated or modern and fuel injected this could be as simple as a vacuum leak or dirty throttle bore, try listening for a whistle noise from the engine and look at the vacuum hoses very carefully for cracking or swelling.
Back

QuestionTire Rotation:  How often should I rotate my tires?                                                          
AnswerThe recommended interval is every 5,000 to 6,000 miles or every oil change.                                                      
Back

QuestionWarm Up Slow:  My car takes a long time to warm up during the winter, the air that blows thru the vents is cool. What do you think is wrong?
AnswerThis should be a simple one as the most common cause is a stuck open thermostat but some thermostats are in very difficult places on newer cars. Other possible causes for this are fan clutch being seized (usually accompanied by extra noise or vibration on the engine area) or an electric cooling fan staying on all of the time.
Back

QuestionFuel Bad:  What should you do if you get bad gas in your engine?
AnswerThis depends on if the gas is just old, has some water in it or if it is comtaminated with the wrong fuel or something worse like the old sugar in the tank thing. If it is making the car run bad or not run at all I suggest getting the gas tank drained, fuel lines and injectors flushed and a new fuel filter installed, in extreme cases you may need to replace the fuel injectors as they have very small screens in them that can get plugged and cause serious problems that flushing will not solve. If it is a minor case of just some water in the gas or old gas you can get some dry gas (Isopropyl alcohol) from most parts stores and fuel injector cleaner, top off of your tank with premium fuel and a new fuel filter to take care of it.
Back

QuestionTurn Signals Intermittent:  My blinkers only work part time. What's wrong?
AnswerPossible causes for this are a bad turn signal switch, flasher relay, a faulty light bulb or connection. When this happens try moving the switch up and down to see if they start working, this would indicate faulty contacts in the switch, a bad ignition switch can sometimes cause this as well but is usually accompanied by other electrical components not working.
Back

QuestionFront End Noise & Steering Sloppy:  My front end is making a squeaky noise when I go over a bump and my steering is sloppy. What could be the problem?
AnswerThis could be a steering or a suspension problem and should be checked right away, ball joints, tie rod ends can cause you to loose control of your vehicle and will squeak when there is no grease in them, the sloppy steering is what I would be mostly concerned with as it indicates a steering linkage problem. The other items to look at are stabilizer bar links / bushings, control arm bushings, struts and strut mounts.
Back

QuestionBrake Maintenance:  How do you know when you need to change your brakes?
AnswerHave your brakes looked at or replaced if you feel a pulsating when you are stopping, hear a grinding or squeal and also if your car wants to pull to one side while braking. Metalic brake pads will sometimes squeal when stopping but not cause any problems or need to be replaced unless it is excessive, also if you feel your brake pedal going lower than normal sinking while you are stopped or the red brake light comes on it is time to check your brake fluid and get in for service right away.
Back

QuestionOil Change Intervals:  Do you really need to change the oil every 3,000 miles?
AnswerActually this depends on your driving habits, if you drive mostly long highway miles then every 5,000 miles is ok and some manufactures will go as high as 7,000 miles but I recommend at least every 5,000. If you drive mostly city stop and go driving, haul heavy loads or pull a trailer then I would recommend ever y 3,000 miles for sure, synthetic oil will also increase the miles you can drive between oil changes by about 3,000 miles over conventional motor oil.
Back

QuestionNew Car Maintenance:  I just purchased a new car. What regular maintenance should I do to make sure that this car will last me as long as possible?
AnswerThe first and most obvious is keeping the oil changed based on your type of driving (city/highway) and making sure that the filters and other fluids as well as tire pressure and rotation are preformed per your manufacture recommendations, it is a good thing to have a mechanic or shop you can trust that will look for things during service that may not be felt or heard but can be seen while on a hoist during an inspection. Also there are technical service bulletins that are published on vehicles that most repair shops can look up for you that show pattern problems and failures for your specific vehicle.
Back

QuestionBrake Pedal Pressure:  Does the amount of pressure applied to the brake pedal effect the lifetime of the brake pads?
AnswerYes the harder you apply the brakes the hotter the rotors get as well as the pads, this will decrease the life of the brake pads and also could wrap the rotors causing a brake pulsation or squealing. The best way to extend the life of your brake pads and rotors is to ease into stops slowly applying and releasing the brake pedal as you come to a stop especially on a downhill grade this gives the brakes and rotors a moment to cool off.
Back

QuestionAlternator Sparks:  I recently was tightening my positive battery cable when I touched the alternator at the same time. It shot off sparks and burned part of the alternator blade. I tried starting the car afterwards. The first three or four times it started but it kept putting out. Now it won't start. It turns over fine as if it wants to start but it won’t fully start.
AnswerFirst, check all of your fuses, there are many in today’s vehicles. Some are easily found, but you may need an owner’s manual to locate others. There are also fusible links (a strand of wire made to separate when overloaded) that do not look like a fuse, but serve the same purpose — circuit protection. This type of problem on a modern vehicle can cause computer type failures but is rare with all of the circuit protection devices in place.
