The serpentine belt (aka drive belt), is the belt that drives the accessories on the front of the engine. It drives the alternator, water pump, power steering pump, air conditioning compressor, and any other belt driven accessories. This is the...
Hi there: It's very difficult to tell you where to start if we don't know what type of troubles or symptoms you're experiencing. A professional mechanic typically will download OBD-II trouble codes first, then test drive or communicate with the...
Hi there: It's possible that you have a faulty or damaged alternator, starter, battery cables or ignition relay that is the source of the no start issues on the Saab. Since there are several components that could be faulty, you...
The sound of the exhaust is not determined by whether it is a turbo-back, or a cat-back system. The determining factors for the amount of sound that comes from a given system are the size of the piping being installed,...
Hello - I suspect the answer to this question revolves around whether you are making other modifications to the engine, and how often you drive with boost pressure near the limit. This device will offer more precise control for managing...
This may be a sign of a failing throttle position sensor. The throttle position sensor (TPS) is a sensor used to monitor the throttle position of the throttle plate inside the throttle body in relation to your foot position on...
As this is a new vehicle, it may be best to make an appointment with your dealership service department. A notchy shifter or difficulty putting it into different gears may indicate some adjustment issues which should be covered by your...
Hello, thank you for writing in. There are so many components that can effect the steering and alignment, that there will need to be several tests and inspections done until we find the issue. Check the tire wear for any...
The only way to determine if the collision caused damage is to carefully MEASURE the alignment and, as well, the frame dimensions using a tram. If those steps have not been specifically taken, what the mechanics have told you about...
Hi there. If your temperature continues to do this then you either have a flow issue within the cooling system or you have a small leak in the head gasket. I usually start by doing a block test on the...
An engine that won't crank indicates a problem with the starting/charging system. Since you said the vehicle will start with a jump, you can rule out the starter and its corresponding control circuitry. The most likely cause is a battery...
Hi There, Generally, a weak starting car is a sign of a weak battery, however this can also be caused by a starter that is beginning to fail as well. Since you just replaced your battery, it is more likely...
Typically, this refers to the output shaft speed sensor, however depending on what you are reading in terms of the research, various literature will call it different things or refer to it differently. If you need additional help with this,...
Your clutch master cylinder is probably out of fluid. Topping it off probably won't do the trick because it now has air in the system that needs to be bled out. You might be able to get some activity out...
Hi Juan. Thanks for submitting your question tonight. Issues at wide open throttle are typically caused by fuel restriction or fuel to air mixture problems, when the engine is getting too much fuel or not enough. This can be typically...
The cycling of the AC compressor is normal as the compressor cycles on and off. You may also hear a bit of a change in the exhaust as this happens. The computer will automatically compensate for the additional load the...
Try to disconnect the battery and wait a few minutes and then reconnect it and start and idle engine for ten minutes to relearn idle. If this does not help then seek a mechanic like one from YourMechanic to test...
From what you describe it sounds like you have front wheel bearings that are noisey. They do not have to be loose to be noisey. Have the vehicle lifted and ran in drive to see if the noise can be...
The engine in your particular model was equipped with a timing chain, not a belt. The screeching noise that you are describing could be due to a faulty bearing in a pulley that is in the "circuit" of components driven...
