Noise in the Engine (right side) - any ideas? 850

posted by  someone claiming to be Yuri on  Wed Nov 24 02:53 CST 2004 [RELATED]

My '95 Volvo 850 with 137K miles recently developed an odd noise. It happens when the engine is started, lasts from .5 to 2 minutes and gradually goes away completely. The noise always happens when the engine is started, even after a short stop. It sounds like creaking/rubbing and pulsates with the engine RPM, like something is rubbing.
It is in the accessory belt area, I suspect it is one of the units there (alternator, steering pump, AC compressor or tensioner pulley). Everyting in that area is still original at 137K miles.

I wonder if anyone heard this. Volvos are failing in the same way, so this can not be unique. The accessory belt was last changed some 20K ago, so it should be still good. Timing belt is up for its second replacement soon, but I hope the noise is not from there.

Thank you.

    Sounds like it may be a worn "front" motor mount. This one is located behind the vibration dampener at the front of the engine. Remove the passenger side front wheel and lift up on the wheel well access cover after removing the two plastic nuts. Jack the engine up and check if the motor mount rubber is split. The metal part of the mount may be rubbing on the frame. It is relatively easy to replace and a good quality one runs around $75. They usually go bad any time after 75K miles.

    Make sure the idler and t belt tensioner bearings are ok.If they fail the t belt fails and we all know what that means.
