This pump is the same as the 1645 but we had good feedback telling use enough people had to swap out a fan hub to match their pulley (F2UA 8509 and E7TA-8509 used from 1987-1996) that we decided to provide a 8 bolt pattern

1895 1982-1993 Chevy GMC 6.2L Diesel CW water pump duramax Why is increased flow soAre you running hot when towing? Flowkooler designed a high flow water pump for the 6. 2L Diesel with a CNC machined billet aluminum impeller to stop the overheating at idle, under a load and in stop and go traffic. It has an increased vane count and a reduced casting to impeller vane clearance. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating
