Davies Craig® DC-8907 - EWP80 Combo Remote Electric Water Pump & Controller

EWP & CONTROLLER INSTALLATION DEMONSTRATION

Combined with an LCD EWP®/Fan Digital Controller 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.
