The original pulley was bent when I tried to remove it. the replacement pump came with a smaller single groove pulley. I have tried to locate an exact replacement for my original double groove pulley but cant seem to find one. the ones I have found are in some way different. I have heard every opinion under the sun and now I have a headache. I now know
pumps are interchangable between years and models. Also a certain amount of belt surface has to make contact with the pulleys of the device the belt is driving. So, lets say I bought the car without a pulley on the pump would it really matter what pulley I installed?
