EWP140 Black - Remote Electric Water Pump (12V)
The EWP®140 Alloy 12V is available for purchase in following options:
- Pump Only (Part #8190)
- Kit (Part #8090)
- Combo with Controller (Part #8980)
Turbocharge your engine cooling with the Davies Craig EWP®140 (Black) Alloy Electric Water Pump. Designed for universal engine fitment to satisfy larger and higher horsepower, turbocharged or supercharged engines which develop excessive heat.
The configuration mirrors the highly successful EWP®80, offering numerous attachment options including elbow and straight adaptors. By removing parasitic power losses of belt-driven pumps, the EWP®140 releases up to 10kW (13hp) of extra power, increased torque and fuel savings. Also extensively used in Intercooler Applications.

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.
universal fit more power more cooling increase fuel efficiency extend engine life world-leading technologyInstalling 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.
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.
- Install the EWP® 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.
