Davies Craig Header Adaptor Kit Chev 8621
The Davies, Craig EWP Header-Adaptor Kit which is designed, in conjunction with an EWP Electric Water Pump Combo Kits (Part Nos. 8030, 8050 or 8070), to replace your existing belt-driven mechanical water pump on the Chevrolet V8 engine.
Further, if your belt-driven, mechanical water pump has a mechanical fan, you will need to replace it with a Davies, Craig 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. Details relating to the most suitable Davies, Craig Thermatic Fan for your vehicle are listed on the Davies, Craig website. If your vehicle is not listed you can follow the guidelines listed to find the most suitable Thermatic Fan for your vehicle's radiator. Remember, flow rate is the vital factor to achieving enough cooling. Please ensure the Electric Fan you select has sufficient air flow, Cubic Feet/Minute (CFM). Many fan manufacturers inflate flow rate figures. If you are not able to confirm the CFM of the fan you plan to purchase - DON'T BUY IT!
