Muscle up your engine cooling system with the Davies Craig EWP®150 alloy Electric Water Pump. Like all EWP®s, this advanced unit is designed for remote mounting in the engine bay to satisfy those higher horsepower, turbocharged, supercharged and ‘worked’ engines which develop excessive heat.
The compact EWP®150 alloy unit is manufactured with -AN16 ORB internal inlet and outlet fitting for neat, tight screw-in fitting applications. This rugged alloy hi-flow electric water pump is designed to complement or replace the engine’s existing mechanical water pump, increasing power and improving coolant temperature control.

EWP & Controller Installation Demonstration
Combined with an LCD EWP®/Fan Digital Controller (Sold separately Part DC8002 or EWP® Combo Pack), the system manages both EWP® and Thermatic® fan operation:
- Varies pump speed in response to coolant temperature.
- Multiple temperature targets for performance or fuel efficiency.
- Activates Thermatic® fan(s) at 3°C (5.4°F) above the set temperature.
- Runs on after shutdown for up to 3 minutes (or until 10°C / 14°F below the set point) to reduce heat soak and help extend engine life.
- Combo Pack includes a DIY kit with everything needed for fitment, plus an instruction booklet.
The world’s most advanced total engine cooling management system:

world-leading technology
Installing an EWP® as an AUXILIARY PUMP
- Leave the mechanical water pump in place and 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 circulation when the thermostat is closed. Refit with clean sealing surfaces and a new gasket if required.
EWP® installation – disabling the mechanical water pump
- Install the EWP® into the bottom radiator hose and remove the manufacturer’s thermostat.
- Bypass the water pump pulley using an appropriate length belt (not supplied).
- If running the pump continuously, drill two approx. 3mm (1/8") holes in the thermostat plate to allow some circulation. Refit with clean sealing surfaces and a new gasket if required.
In both cases, the EWP® pumps past the impeller of the mechanical water pump.
Disengaged mechanical water pump (recommended)
- Remove the thermostat and mechanical water pump.
- Remove the impeller from the pump shaft, then refit the pump and pulley as an idler to avoid re-routing the drive belt.
- Block bypass passages and refit with clean gasket surfaces and correctly installed gaskets to prevent leaks.
- Install the EWP® into the bottom radiator hose.
Removed mechanical water pump (ideal)
- Remove the mechanical water pump and thermostat.
- Install a Davies Craig EWP® header adaptor or blanking plate (not supplied), using the correct gasket or sealant on clean surfaces.
- Install the EWP® into the bottom radiator hose (hose modification/replacement may be required).
- Fit an appropriate length belt (not supplied) to drive accessories.
In most cases the EWP® is supported by the radiator hose. If mounting is required, soft-mount the pump to protect against vibration. For EWP®115, EWP®140 and EWP®150, mounting bracket Part DC8700 or DC8710 is recommended.
