The introduction of front wheel drive and down sizing of vehicles has led to a rapid growth of electric cooling fans for engine cooling. An efficient and economical method of automotive cooling, electric fans are also the fastest growing segment within Cooling System Products.
With multiple uses for primary and supplemented add-on cooling, electric fans are quickly becoming one of the most important cooling components on today’s vehicles.
As a primary cooling source electric fans provide: • Economical replacement for failed OE parts.
• 5-10% increase in engine power, fuel saving when replacing fan clutch & fan assembly
• Reversible blades for pusher (upstream) or puller (downstream) applications.
• Compatibility with all electric fan controls.
• Coverage for a wide variety of applications.

Electric fans are an excellent solution for vehicles requiring additional air flow. As an add-on cooling source electric fans reduce the workload on the primary cooling fan. Additional air flow increases the operating efficiencies on applications from small to recreational vehicles.

As an add-on cooling source electric fans provide: • Constant air flow regardless of vehicle speed.
• Increased air conditioning performance due to constant air flow across the condenser.
• With the conversion from R12 to R134A refrigerant there is a need for additional condenser
cooling to ensure the overall improved efficiency of the cooling system.
• increased fuel economy.
All Davies, Craig electric fans are packaged complete with instructions and mounting hardware for quick and easy installation.

The world’s first universal fit, automotive Electric Water Pump. Replaces and out performs existing belt drive water pumps. Designed to be installed in the bottom radiator hose. The revolutionary designed Davies, Craig EWP Electric Water Pump is a performance accessory that increases cooling capacity while giving you more engine power - in fact up to 20HP (15kW) more power.
The EWP fits most makes and models of cars on the road today. The kit comes with everything needed for easy installation including easy to understand - do-it-yourself instruction.

EWP 'smart' Controller Installation procedure:

Combine with the Davies, Craig EWP Electric Water Pump for optimum engine cooling system performance;
Mount controller box under dash;
Connect colour coded relay harness and EWP wire loom to the mating connectors on controller and pump;
Place the temperature sensor in engine thermostat position.

A Thermal Switch is a temperature device which senses the temperature of the radiator and turns on the electric fan when cooling is needed. The Thermal Switch is adjustable over a wide range of temperatures by turning an adjustable screw located on the controller.

The Mechanical Thermal Switch is adjustable from 80degC-115degC. The Thermal Switch is mounted next to the radiator and the copper probe is mounted inside the radiator hose. The Thermal Switch is then connected to the ignition circuit for operation. The Thermal Switch and Relay Kit enables a fan to operate both thermally and also when air conditioning is running.

The Electronic Thermal Switch Kit is adjustable from 40degC-100degC. The Thermal Switch, Relay and Wiring Loom all come connected ready for mounting. The Thermal Switch can be operated both thermally and also when the air conditioner is running. The Electronic Thermal Switch has an advantage over the Mechanical Thermal Switch in that the probe can be placed between the fins of the radiator and does not have to be placed inside the radiator hose.
