General Motors Holden 253-308 EWP® Block Adapter Kit (Part #8600)

The Holden 253-308 EWP® Block Adapter is designed for use with EWP® Electric Water Pump Combo Kits to replace the belt-driven mechanical water pump on the 253, 304, 308, and 355 GM Holden engines.

Note: For the heater return hose, you will need the Heater Return Adapter (Part #8380). Place this adapter before the EWP as demonstrated in the installation video. Some older vehicles with a heater pipe featuring two hose connectors (one for the sender and one for the return) may require two Heater Return Adapters (Part #8380). In this case, one adapter should be placed before the EWP for the heater return and the second after the EWP for the heater sender hose.
