Q: Whining from tensioner or AC compressor

asked by on

When the car starts, I can hear a whining sound coming from the area of the tensioner or AC compressor. Once the car warms up, it stops.

Hi there, if the problem only occurs when the engine is cold then it is most likely the tensioner or something to do with the timing chain. The A/C compressor would create the noise when the A/C is turned on, regardless of engine temperature. Have a certified technician help you locate the sound.
