EWP& CONTROLLER INSTALLATION DEMONSTRATION

 

Combined with an LCD EWP®/Fan Digital Controller (Sold separately Part#8002 or EWP®Combo Pack) will manage both the EWP® and Thermatic® fan operation. The Digital Controller will vary the speed of the EWP® in response to the engine’s coolant temperature. Multiple temperature settings are provided on the Controller for either maximum power or fuel efficiency. The Thermatic® Fan/s will be activated automatically once the engine coolant rises 3°C (5.4°F) above the targeted (set) temperature. The Digital Controller will automatically run on for three minutes (or to 10°C/ 14°F below the set temperature) after engine shut down, eliminating‘heat soak’ and extending engine life. The EWP®Controller Combo Pack is supplied in a do-it-yourself kit with everything you need for fitment to your vehicle’s engine, including an easy-to-follow DIY instruction booklet.

EWP®INSTALLATION OPTIONS

Installing an EWP®as an AUXILIARY PUMP

  • Leaving the mechanical water pump in place, install the EWP® into the bottom radiator hose.
  • Remove the thermostat and drill two approx. 3mm (1/8") holes in the thermostat plate to allow some coolant circulation when the thermostat is closed. Re-install ensuring that the thermostat housing is clean and a new gasket is used if required.

EWP® INSTALLATION– disabling Mechanical water pump

  • Leaving the mechanical water pump in place, install the EWP® into the bottom radiator hose and remove the manufacturer’s thermostat.
  • You will need to bypass the water pump pulley by installing an appropriate length belt (not supplied). This method makes for an easy installation.
  • If running the pump continuously remove the thermostat and drill two approx. 3mm (1/8") holes in the thermostat plate to allow some coolant circulation. Re-install ensuring that the thermostat housing is clean and a new gasket is used if required.

In both these cases, the EWP® will pump past the impeller of the mechanical water pump.

Disengaged mechanical water pump (recommended)

  • Remove the mechanical water pump and remove the thermostat.
  • Then remove the impeller from the mechanical pump shaft. Retain the mechanical water pump using the pump pulley as an idler to avoid re-routing the drive belt.
  • Block any bypass passages and re-install the disengaged water pump ensuring that all gasket surfaces are clean and the new gaskets are properly fitted to prevent leaks.
  • Install the EWPÒ into the bottom radiator hose.

Removed mechanical water pump (Ideal)

  • Remove the mechanical water pump and thermostat from the engine.
  • Install a Davies Craig EWP® Header Adaptor or blanking plate (not supplied). Ensuring the gasket surfaces are clean and the appropriate gasket or sealant is used to prevent leaks.
  • Install the EWP® into the bottom radiator hose. This method will require you to modify or replace the standard radiator hose.
  • Install an appropriate length belt (not supplied) to drive the accessories.

In most cases EWP® will be adequately supported by the radiator hose. Where mounting is required, the EWP® must be soft mounted to protect against vibration. For the EWP®115, EWP®140 and EWP®150 Part #8700 or #8710 Mounting bracket is recommended.
