EWP115 ALLOY REMOTE ELECTRIC WATER PUMP (12V) (#8140)
EWP®115 Alloy Remote Electric Water Pump (12V) (PART #8140)
The EWP®115 Alloy (12V) is available for purchase in following options:
- Pump Only (Part #8140)
- Kit (Part #8040)
- Combo with Controller (Part #8950)
The EWP®115 pump is suitable for small, medium, large, high- performance and 4WD vehicles. It’s a performance product that improves engine cooling control and capacity whilst giving you more power and torque and improved fuel economy.
The EWP®115 is a practical alternative to the mechanical belt-driven pump or fitted as an auxiliary pump. Mechanical belt-driven water pumps run directly off the motor and sap engine power … the EWP®115 is hardwired into your electrical system, by-passing the engine and releasing up to an additional 10kw (13hp).

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.
