EWP80 Alloy Combo - Remote Electric Water Pump & Controller (12V)

The EWP80 Alloy Electric Water Pump – simple, do-it-yourself, easy to install, designed to complement or replace your existing belt-driven, mechanical water pump. It will fit most vehicle makes and models and can be installed on the bottom radiator hose of most vehicles equipped with naturally aspirated engines up to two litres (2000cc).

The revolutionary, Australian-designed EWP80 Alloy is made from lightweight aluminium which offers great thermal conductivity and incorporates a ceramic faced seal for long-life durability.

With a maximum flow rate of 90 l/min (24 g/min), 35mm (13/8”) inlet and outlet, arrives in magnificent matt-black, powder-coated finish and offers the same high class, performance, compactness, and style you have come to expect from the world’s largest supplier of remote-mounted electric water pumps and world-beating engine cooling products company, Davies Craig Pty Ltd.

Customers continue to enjoy superior engine cooling technology using Davies, Craig’s extensive range of remote-mounted Electric Water Pumps (EWP) combined with the patented LCD EWP/Fan Digital Controller, commonly called EWP Combo Packs!

The EWP80 greatly enhances engine cooling control while giving you added power and improved fuel economy. By removing the parasitic power losses of a belt-driven, mechanical water pump the EWP can provide up to 10kW (13hp) of extra power and increased torque and used extensively in Intercooler applications.

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.
