New DIESELSITE High Output BILLET IMPELLER 6.0L Ford Powerstroke water pump with gasket. Fits all 2003 - Early 2004 (build date before 9/22/03) 6.0L engines. All Dieselsite water pumps come with a lifetime warranty to the original purchaser.
High Output Flow Water pump. Delivers 25% more coolant flow to help the early 6.0s with the heating issues they have.
In 2004.5-2007 Ford upgraded the 6.0 Powerstroke water pump to overcome 2 shortcomings of the earlier model: Consistent failures of the plastic impeller Inadequate coolant flow
When we looked at these concerns, we wanted to overcome these while still maintaining a economical solution. We took our technology from producing the Wicked Wheel 2 billet turbo compressor wheels. If we could make an impeller with the same aircraft quality aluminum we would increase the strength and if designed properly, increase coolant flow thus overcoming the heating issues of the early model 6.0 Powerstrokes.
Some companies have approached this by developing a complete billet water pump. While this may be very attractive, the functionality of the pump is more important at an affordable price.
