The alternator is one of the most common problems, as is the idler pulley. These would need to be checked to see if this is the noise. The best way to diagnose the problem is to have a mechanic listen...

Valve cover gasket leaks are located by visual inspection and are usually one of the easier leaks to confirm the source of, since they are high up on the engine. It would't hurt to wash it off, especially if it's...

This may be a sign of a faulty MAP sensor as the vehicle responds adversely to a load put on the motor (i.e. putting it in gear, making turns (which makes use of the power steering pressure switch) turning on...

Yes, this needs to be checked out and the boost pressure sensor replaced if it has failed. Your engine is turbo-charged, which means an air pump, driven by exhaust pressure, may force more air into your engine to achieve more...

Hi there. Check to see if the vacuum pump has seized up on the engine. If the pulley is not turning then the belt will make a screeching noise and put a huge load on the engine. The extra load...

Hello. Without additional info as to what the car is doing this may be hard to diagnose without seeing the car and listening to it in person. You'll first want to check if it is making a clicking sound or...

Hi, thanks for writing in. You will need to have the cooling fan clutch checked to see if it is working properly. The engine will not cool properly if the clutch is not locking enough as the engine gets hot....

Hi there. It sounds like there is a possibility of a fault with the MAP sensor system for the P0108 code, an EGR fault for the P0401, and a catalytic converter fault for the P0420 code. Your concern could be...

It could be the alternator. You can go and have any mechanic, anywhere take a look. Most guys do it free--they can check your batteries and alternator. It takes five minutes and they can tell you if the battery is...

If you want to continue to change transmission fluid on a regular basis then you can do it every 30,000 miles or 3 years. This is a good timing since you did it 1 1/2 years ago, you have another...

Hi there. There are several reasons for a no start condition. It could be a timing belt if the engine turns over faster than usual. It could be a fuel pump, even though it is heard (pressure not within specification)....

Hi Carlos. Thanks for contacting us today. Usually, the cold hose below and hot one above issue is caused by a failed water pump or thermostat, which can lead to overheating issues rather quickly. An obstruction of debris inside the...

There is a short somewhere causing the lights to work intermittently. However, to provide more insight as to where the short might be, I would need to know exactly which lights are illuminating intermittently. I'm guessing that it is not...

Hello. If the vehicle is throwing a code for the throttle body, then it may be possible that it has failed. Your particular model of vehicle uses an electronic throttle body that is actuated by an electric motor controlled by...

An engine can ping (or knock) due to an improper combustion process. An ignition knock is the result of combustion occurring too early. Early combustion can occur from carbon buildup inside the combustion chamber, a lean air/fuel mixture, and advanced...

It sounds like you may have a fuel pump issue. Often times the fuel pump will operate until the pump motor gets warm and then it will loose contact inside. once it cools down then it will make contact again...

It sounds like you may have an overheating issue that may very well be related to the fact that there was no coolant in the radiator, however it is also possible that there may be other issues that may have...

Hello, thank you for writing in. With white smoke coming from the exhaust, the smell of coolant, and the (very likely although unmentioned) lowering of the coolant level, it is quite apparent that the coolant is making its way passed...

The car's self diagnostics should be able to tell you if there is a leak in the line, The EVAP monitor will pull a vacuum on the tank and keep track of the fall in pressure. It will light the...

Hello - the use of "sealing" products is a bit of a religious discussion. Some swear by them, others swear at them. Yes, they will sometimes seal a small leak, although head gaskets are less likely to stay sealed due...

The window regulator in that door has broken. The window regulator uses a series of cables and pulleys to move the window up and down. Oftentimes, the pulleys, (which are made of plastic,) will break. When this happens, the cables...

Hello. If your cylinder one is not firing then I would test to make sure that the coil is getting power and go from there. If it isn't then it may be possible that the computer is bad, as that...
