Comments about Dorman - OE Solutions Engine Water Pump Pulley:

GM screwed up when they made this pulley out of plastic. Installation is easy as long as you have a power steering pump pulley remover and installer. There is no other way to do with without damaging the cam

  • Q:

    I am attempting to locate a pulley that drives the belt for the water pump on my 99 Olds Aurora. This pulley sits on the end of the overhead cam - not the pulley on the water pump or the tensioner pulley. The once currently on the car is plastic and has failed. Can you tell me if the part indicated (Engine Water Pump Pulley) is the correct replacement?

      I recommend purchasing a Haynes repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair or replace specific parts.

      Removing the water pump pulley from the cam requires GM tool J 38825. Installation requires J 38823. OEM Tools 27031 is a puller/installer set that handles both tasks.
