FAQs

What is the main benefit of using an electric water pump over a mechanical one?

Electric water pumps allow coolant circulation even after the engine is shut down, preventing hotspots and reducing heat soak. They also enable more precise temperature control, potentially increasing engine power, torque, and fuel efficiency.

Do I need the digital controller to use the EWP150?

While the EWP150 can function as a standalone pump, the digital controller is highly recommended to achieve its full benefits, including optimized warm-up, precise temperature management, and post-shutdown cooling.

What is the flow rate of the EWP150?

The EWP150 offers an optimum capacity of 150 Litres per minute.

Can I use different sized hoses with the EWP150?

The pump accepts 38mm bore push-on hose directly. Adaptors are available separately for larger hose sizes up to 50mm bore.

How is the temperature sensor installed?

The temperature probe can be mounted in the thermostat housing, top radiator hose, or in the engine block close to the coolant outlet. An in-line adaptor for 35mm bore hose is included.

What is the default temperature setting on the digital controller?

The digital controller is factory set to 85°C, but it offers 9 user-settable temperatures ranging from 60°C to 100°C.

What happens if the engine temperature exceeds 100°C?

An audible alarm will sound if the engine temperature exceeds 100°C, indicating a potential issue with the cooling system that needs to be addressed.

Troubleshooting

Pump not running

Check the wiring harness connections to the pump and controller. Ensure the pump is receiving power and the controller is functioning correctly. Verify that the engine temperature has reached the trigger point for pump activation.

Overheating despite pump operation

Check for coolant leaks, air pockets in the system, or blockages in the radiator or hoses. Ensure the pump is correctly installed and oriented. Verify the digital controller is set to an appropriate temperature.

Controller not displaying temperature

Confirm the temperature sensor is properly connected to the controller and the engine. Check the sensor's wiring for any damage. Ensure the controller unit is receiving power.

Audible alarm sounds

If the high-temperature alarm sounds (over 100°C), address potential cooling system blockages or insufficient flow. If the 'cold engine' alarm sounds (40°C not reached within 5 mins), ensure the thermostat is functioning correctly and the pump is circulating coolant effectively.

Pros and Cons

Pros

  • Superior engine temperature control for increased longevity.
  • Potential for gains in horsepower, torque, and fuel efficiency.
