EWP140 Black - Remote Electric Water Pump (24V)

Turbocharge your engine cooling with the Davies, Craig EWP140 (Black) Electric Water Pump. The world’s first universal fit / remote mount Electric Water Pump.

Suitable for naturally-aspirated and turbo / supercharged engines up to 5 litres. Like all the EWPs, this unit is designed for universal engine fitment to satisfy those larger and higher horsepower engines which develop excessive heat. It increases power and improves coolant temperature control by removing parasitic power losses.

Installation demonstration & controller overview

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.

Key benefits

The world’s most advanced total engine cooling management system:

• universal fit
• more power
• more cooling
• increase fuel efficiency
• extend engine life
• world-leading technology

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.

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.

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).
• Install the EWP into the bottom radiator hose. This method will require you to modify or replace the standard radiator hose.

In most cases EWP® will be adequately supported by the radiator hose. For the EWP115, EWP140 and EWP150 Part DC8700 or DC8710 Mounting bracket is recommended.
