Product Details

Davies Craig Electric Water Pump Header-Adaptor Kit

The Davies, Craig 8621 EWP Block-Adapter is designed, in conjunction with an EWP Combo Kit to replace your existing belt-driven mechanical water pump on the Chevrolet big block V8 engine.

Further, if your belt-driven, mechanical water pump has a mechanical fan, you will need to replace it with a electric Thermatic fan. If you have purchased an EWP Combo Kit, then you will have an EWP & Fan Digital Controller with a built-in switch that will control the electric Thermatic Fan in unison with your new EWP.

Hose Fitting Sizes: All Davies, Craig EWP115/150 Electric Water Pumps are manufactured with 38mm (1 1/2”) OD inlet and outlet. The alloy versions of the EWP 115/150 Electric Water Pumps have been manufactured with AN-16 internal threads should you wish to fit screw-in hose fittings. If your radiator hoses have a larger inside diameter (ID), Davies Craig can supply 3mm (part no. 8510) and 6mm (part no. 8511) Rubber Adapter Sleeves to suit.
