EWP80 - 12V 80LPM/21GPM REMOTE ELECTRIC WATER PUMP (12V) (PART #8105)

The EWP80 is available for purchase in following options:

• Pump Only (Part #8105) 
• Kit (Part #8005)
• Combo with Controller (Part #8907)

The EWP80 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 fitted with naturally-aspirated or turbo engines up to two litres. The revolutionary, Australian-designed EWP80 is made from anti-corrosive, lightweight, heat-resistant, glass-filled nylon and incorporates a ceramic faced seal for long-life durability.

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.

EWP & CONTROLLER INSTALLATION DEMONSTRATION

Combined with an LCD EWP/Fan Digital Controller (Sold separately Part #8002 or combo #8907) 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 EWP80 Digital Controller Combo 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 EWP^Ò 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 EWP115, EWP130 and EWP150 Part #8700 Mounting bracket is recommended.
