The addition of the Davies Craig Electric Water Pump Block Adapter, coupled to one of the EWP®115, or EWP®130 or the EWP®150 Electric Water Pump Combo Kit will:

  • Replaces belt-driven mechanical water pump.
  • Increases engine horsepower!
  • Provides superior engine cooling control!
  • Eliminates heat soak!
  • Simple do-it-yourself ‘plug & play’ installation using some existing water pump hardware 


This exciting new product allows end-users to enjoy the benefits of the superior engine cooling technology Davies, Craig Electric Water Pump (EWP®) and the LCD EWP® / Fan Controller Combo Pack offers.

Deleting the existing mechanical iron-age water pump from the front of the engine block frees up valuable space to fit a high performance 14” or 16” Davies Craig Thermatic® fan!
