Davies, Craig Block Adapter Kit to Suit GM/Holden 253, 304, 308 V8 Engines - 8600

The EWP block adapter is designed in conjunction with an EWP electric water pump combo kit, to replace your existing belt-driven mechanical water pump on the 253, 304, 308 and 355 GM Holden engine.

Note: For the heater return hose, you will need the Davies Craig Heater Return Adapter (Part number 8380). Place this unit before the EWP as per the demonstration video.

Some older vehicles may have a heater pipe with two hose connectors, one for the sender and the other for the return. In these instances, you will need 2 x Heater Return Adapters (Part No. 8380). Place one adapter before the EWP, this will be your heater return, then place the second adapter unit after the EWP, this will be for your heater sender hose.
