My 2001 Honda Passport is making a grinding noise from the serpentine belt area.. We think one of the pulleys barrings are going bad but not sure... any suggestions or anyone know a solutionMy 2001 Honda Passport is making a grinding noise from the serpentine belt area?You have bearings going out somewhere in one of your pullys 100% guarentee it 100% turn your ac on and see if the noise increases if it does its probably you ac pulley. Not a hard problem to fix. My aunt has a 2000 passport not too hard to work on , 2 motors later she still has it. Hope this helps.
