i was looking at my belts last ngiht and noticed that the water pump pulley is not aligned wiht the others. it sits about a half inch back from the others. i removed the fan lastand pulled the pulley during the summer, due to the fan being damaged from a accident. i dont remember any kind of spacer behind the pulley that would make it sit more forward to align with the others is this normal or do i need to shm it out till it aligns? also is 3 inches a tolerable distance for the fan to sit back from the face of the radiator? thank you.
