EWP^®115 Nylon Combo Remote Electric Water Pump & Controller Combo (12V) (Part #8930)

The EWP^®115 Nylon 12V is available for purchase in following options:

• Pump Only (Part #8125) 
• Kit (Part #8025)
• Combo with Controller (Part #8930)

Take total control of your engine cooling with the Davies Craig EWP^®115 Nylon Electric Water Pump and LCD EWP®/Fan Digital Controller. The Controller will also manage the operation of your Thermatic® Fan. The EWP^®115 pump is suitable for small, medium, large, high-performance and 4WD vehicles. It improves engine cooling control and capacity whilst giving you more power and torque and improved fuel economy.

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 the LCD EWP^®/Fan Digital Controller, the pump continues to run after you’ve switched off, eliminating “heat soak” and extending engine life. Our EWP range are also extensively used in Intercooler Applications.

Davies, Craig’s revolutionary, Australian-designed EWP^® pumps are made from anti-corrosive, lightweight nylon reinforced with fibreglass. Universal fit allows for easy mounting into the bottom radiator hose. Our kits come with easy-to-understand DIY instructions and everything you need for easy installation, including different adaptors to fit various hose sizes and all necessary electrical wiring.

The EWP^®115 and LCD EWP^®/Fan Digital Controller Combo Pack is the most economical way to increase horsepower and save on fuel consumption whilst caring for your engine.

The Davies, Craig EWP^® header adaptor kit can replace the mechanical water pump completely. (See EWP^® Header Adaptors on website)

EWP & CONTROLLER INSTALLATION DEMONSTRATION

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 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 EWP^®115, EWP^®140 and EWP^®150 Part #8700 or #8710 Mounting bracket is recommended.
