A fiercely proud Australian company, Davies Craig has gone to great lengths to keep the manufacture of their products at home in Melbourne Victoria, utilizing a local workforce. Davies Craig was founded by engineers Daryl Davies and Bill Craig, has revolutionized automotive cooling with their innovative products. In 1971, they introduced the Thermatic Fan, the first electric alternative to belt-driven fans, setting a new industry standard. In 1999, they launched the EWP80, the first Electric Water Pump, further enhancing engine efficiency and gaining adoption by major European manufacturers. Known for their commitment to technology, service, and quality, Davies Craig offers a comprehensive range of high-flow electric water pumps, fans, and digital controllers. Their dedication to customer service, along with their ISO 9001 certification, has solidified their reputation as a global leader in automotive cooling solutions.

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).

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 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.

Fitment Notes:

• Suitable for Engines up to 2.0LT - 3.5LT (Standard)
• Suitable for Intercooler (depending on capacity)
• 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.
