Extended Product Information

FAQs

What is the main benefit of an Electric Water Pump (EWP)?

The primary benefit is improved engine temperature control, allowing for more consistent performance, potentially increased power, better fuel economy, and extended engine life by preventing hot spots.

What engine sizes is the EWP115 suitable for?

The EWP115 is designed for engine capacities ranging from 2.0 to 3.5 litres.

Can I use this pump without the digital controller?

Yes, the pump can be fitted as a standalone item. However, to achieve the full benefits of optimized temperature control and features like post-shutdown cooling, using it with the recommended digital controller is highly advised.

What are the user-settable temperature ranges for the controller?

The controller can be set to a desired temperature between 60°C and 100°C. It is factory set to 85°C.

How do I connect the temperature sensor?

The temperature sensor can be mounted in the thermostat housing, the top radiator hose (using the provided adaptor for 35mm hose), or directly in the engine block close to the coolant outlet.

What happens if the engine temperature exceeds the set point by 10°C?

An audible alarm will sound to alert the user that the engine temperature has exceeded the set point by 10°C.

Does the pump run after the engine is switched off?

Yes, when used with the digital controller, the pump can run after engine shutdown to eliminate hot spots. It operates for 3 minutes or until the temperature is 10°C below the target temperature, whichever comes first.

What hose sizes does the pump accommodate?

The pump's inlet and outlet accept 38mm bore hose. Adaptors are available separately for larger bore sizes up to 50mm.

Troubleshooting

Pump not operating

Check all electrical connections to the pump and controller. Verify the controller is receiving power and is set to an active temperature range. Ensure the temperature sensor is correctly installed and providing readings.

Overheating or insufficient cooling

Confirm the correct target temperature is set on the controller. Check for airlocks in the cooling system. Inspect hoses for any kinks or blockages. Ensure the radiator is clean and airflow is not obstructed. Verify the pump is correctly sized for the engine capacity.

Controller display not working

Check the power supply to the controller. Inspect the wiring harness for damage or loose connections. If the display remains blank, the controller may require replacement.

Audible alarms triggering unexpectedly

Review the set temperature thresholds. Ensure the temperature sensor is accurately reflecting the engine's actual temperature. If the engine is genuinely exceeding safe operating temperatures, investigate the cause of overheating.

Pros and Cons

Pros

  • Significant cost saving compared to buying pump and controller separately.
  • Improves engine cooling efficiency, leading to potential power gains.
  • Advanced digital controller offers precise temperature management and alerts.
  • Extends engine life by preventing hot spots and maintaining optimal temperature.
  • Reduces engine warm-up time and improves fuel economy.
  • Durable construction with anti-corrosive materials.

Cons

  • Installation requires mechanical knowledge and may be complex.
  • Adaptors for non-standard hose diameters (larger than 38mm) are sold separately.
  • The kit is best utilized with the digital controller; standalone use offers fewer benefits.
  • Audible alarms may be intrusive for some users.
  • Requires careful sensor placement for accurate temperature readings.

Setup, Compatibility & Care

Setup: The kit includes the EWP115 pump, digital controller, mounting bracket, wiring harness, in-line temperature sensor adaptor (fits 35mm bore hose), temperature sensor, hose clips, and a blanking plug. Installation involves removing the existing mechanical water pump and installing the EWP115. The digital controller's temperature sensor should be mounted in a suitable location, such as the thermostat housing, top radiator hose, or engine block near the coolant outlet. Wiring requires connecting the controller to the pump and vehicle power. Ensure all hose connections are secure using the provided clips, and use adaptors if your hose size differs from the 38mm inlet/outlet of the pump.

Compatibility: The EWP115 pump is designed as a universal fit for engines with capacities between 2.0 and 3.5 litres. It accepts 38mm bore hose as standard. Adaptors are available separately for larger hose sizes up to 50mm.

Care: Regularly inspect hose connections for leaks. Clean the pump housing and surrounding areas periodically. The digital controller requires no user maintenance beyond setting the desired temperature. Ensure the temperature sensor remains clean and free from debris for accurate readings.
