SYMPTOMS OF A BAD BELT TENSIONER
Symptoms that typically indicate an automatic tensioner has reached the end of the road include:
* Belt slipping (due to loss of tension). Watch the tensioner arm movement while the engine is idling. There should be a gentle arm motion as accessories turn on and off (such as the A/C compressor clutch engaging and disengaging). If the tensioner pulley does not move at all, the tensioner may be stuck. You can test for this later with the engine off. Also watch for excessive chattering or tensioner arm oscillation while the engine is idling. This can be caused by a worn damper inside the tensioner. Excessive arm oscillation should be viewed as a warning sign that the damper has possibly failed or is failing and the tensioner needs to be replaced now. If it is not replaced, it can have a hammering effect on nearby accessories causing the shaft bearings on the accessory to fail.
