The water pumps were made in Italy and were used on several engines like the DeLorean and the Volvo. If the pulley won't go down far enough, then it wasn't pushed down far enough or they used a spacer in the back under the pulley that's to big. The pulleys that P.J.Grady builds and I use on my pumps as well have the spacer built in for the correct depth. John Hervey www.specialTauto.com << The previous owner of my Delorean replaced the water pump with a Volvo part. It appears the pulley will not go far enough on the shaft to line up with crankshaft and alternator. Anyone know if this should have worked or what the correct replacement part would be? >>
