Q: What do I do if is overheating?

If the Check Engine Light is on this would be helpful as the codes that would be triggered by this would generate useful information relating to the problem. Without the benefit of hooking the car up to a scanner and...

Hey there, thanks for writing in. The noise can be the serpentine belt tensioner not putting enough tension on the belt. In this case, you would most likely need to replace the tensioner (https://www.yourmechanic.com/services/drive-belt-tensioner-replacement) along with the belt (https://www.yourmechanic.com/services/serpentine-drive-belt-replacement) to...

As you may know, ethanol attracts and bonds with water from the air, and that water can separate out inside the tank due to phase separation. If your vehicle sits for long periods between use, the moisture settles to the...

When the voltage regulator is not working properly, this may result in the alternator allowing too...

ECM replacement does not implicate the engine lubrication or cooling systems. It is possible the fluid levels were already low when the vehicle was presented for service although admittedly it is also possible to envision a scenario where a shop...

When the car is moving, versus stopped, there is more air flow over the condenser (the heat exchanger in front of the radiator) and that airflow is essential to system operation. To maintain airflow when the car is in stop...
