FAQ		 Installing the EWP Controller
Installation of the optional EWP control unit includes:
  • Modifying the stock thermostat.
  • Installing the temperature sensor supplied with the EWP control unit.
  • Wiring in and mounting the control box.
  • Changing the wiring to the EWP relay.
The stock thermostat is eliminated to allow the EWP Controller to manage the cooling system.

It is not possible to simply remove the thermostat from the b-engine as the thermostat incorporates the seal for the housing cover. So the thermostat is modified by cutting and removing the center section so that coolant always passes through it. It is then reinstalled.

Cut the arms where indicated by arrows to remove the center section of the stock thermostat.
Step 1 - Remove and Modify the Stock Thermostat

Remove the thermostat housing cover and remove the engine thermostat.
The stock thermostat with its center section removed, ready to be reinstalled.


Using a pair of strong clips or a small saw, remove the center section of the thermostat by cutting the 'arms' that go around the spring.

Once removed, only the outer ring and gasket should remain.
