1998 Pontiac Bonneville Repair Question
My 1998 pontiac bonneville makes a little grind noise only when i rev it up high so i took the engine cover off and show a little leak by my head gasket and i put my hand on the head gasket cover and every time i heard that noise i felt something hit/vibr
Adding oil to the compressor does nothing for the pulley bearing, if that is what you were hoping to achieve. If you have a grinding noise, try removing the belt and running it to try and duplicate the symptom, not for too long or overheat/battery discharge will occur. Spin each pulley by hand and try to differentiate which accessory is making noise.
