Extended Product Information

FAQs

Is an installation kit included with the EWP140 pump?

No, this specific variant (MPN: 8190) is the pump only. An installation kit must be purchased separately.

What engine sizes is the EWP140 suitable for?

It is ideal for large capacity engines ranging from 3.5 to 5.0 liters, as well as high-revving competition engines.

Can I use the EWP140 without a digital controller?

Yes, it can function as a standalone unit. However, for optimal performance and precise engine temperature management, using it with a Davies Craig digital controller is highly recommended.

How does an electric water pump improve engine power?

By circulating coolant more efficiently and allowing controlled shut-off operation, it helps maintain optimal engine temperatures, reducing parasitic drag from a mechanical pump and preventing power loss due to overheating.

What material is the EWP140 constructed from?

The pump features a robust, powder-coated aluminum alloy body for durability and corrosion resistance.

How often should I check the pump?

Regular checks of your coolant level and overall cooling system health are advised. The pump itself requires minimal maintenance but ensure electrical connections remain clean and secure.

What is the flow rate of the EWP140?

The EWP140 has a high flow rate of 140 liters per minute.

Troubleshooting

Pump not circulating coolant

Verify electrical connections are secure and receiving power. Check for any blockages in the coolant lines or the pump inlet/outlet. Ensure the pump is correctly primed.

Overheating persists

Confirm correct pump rotation direction. Check for air pockets in the cooling system. Ensure the radiator and fan are functioning correctly. Verify the coolant mixture is appropriate.

Unusual noise from pump

Check for impeller damage or foreign objects. Ensure the pump is securely mounted. Verify adequate coolant flow to prevent cavitation.

Low coolant flow

Inspect for kinks or blockages in hoses. Ensure the pump is correctly sized for the engine. Check the coolant level and system pressure.

Pros and Cons

Pros

  • Significantly improves coolant circulation compared to mechanical pumps.
  • Helps prevent engine hot spots and extends engine life.
  • Can lead to measurable increases in engine power and torque.
  • Enhances fuel efficiency by maintaining optimal operating temperatures.
  • Durable, corrosion-resistant construction for longevity.

Cons

  • This variant does not include an installation kit, requiring separate purchase.
  • Requires careful integration with the cooling system, potentially needing professional installation.
  • Optimal performance relies on pairing with a digital controller (sold separately).
  • May require electrical system modifications for power supply.
  • Higher initial cost compared to some basic replacement pumps.

Setup, Compatibility & Care

Setup: This product is the electric water pump only. Installation requires a compatible Davies Craig installation kit (sold separately), which includes necessary adaptors for hose sizes and wiring harnesses. Professional installation is recommended to ensure proper integration with your vehicle's cooling system and electrical setup. For optimal performance, consider pairing the EWP140 with a Davies Craig Digital Controller.

Compatibility: The EWP140 is designed for large capacity engines (3.5 to 5.0 liters) and high-revving competition engines. Always verify compatibility with your specific engine make and model. Installation kits are available for various hose sizes and configurations.

Care: The pump's exterior should be kept clean. Periodically check coolant levels and the overall health of the cooling system. Ensure the pump's electrical connections are secure and free from corrosion. No internal maintenance is typically required for the pump itself under normal operating conditions.
