I want to replace the water pump on my D and am curious to know which is the best way to go. It seems to be a choice between one that has a pressed-on pulley similar to the original vs. getting a Volvo pump that uses a bolt-on pulley. Apparently there are advantages/disadvantages both ways. The problem with the bolt-on variety is that I don't know of any vendors who sell the pulley. Also, I've heard that there have been problems with some custom made pulleys not lining up correctly. But I like the idea of the bolt-on variety because if I ever had to replace it in a pinch, I could probably get a Volvo pump easier than I could get something Delorean specific. If someone makes a custom pulley that is billet aluminum, it would be cool to get matching ones for the rest of the car. Does anyone know any sources? If you have experiences which are appropriate to share on the DML then do so, otherwise e-mail me privately. Walt Tampa, FL
