Davies Craig EWP80 Alloy Flange Combo - Remote Electric Water Pump & Controller (12V) - DC8908

12 Volt | Part Number: #8908

The EWP^® Kit is a convenient, all-in-one solution for new electric water pump installations, particularly suited to intercooler and auxiliary cooling applications where simple on/off control is preferred. Each kit includes the essential components required to install and wire the EWP® into your system, making setup straightforward and hassle-free.

Delivering an impressive open flow rate of 90 litres per minute (23.8 g/min)

The EWP®80 Alloy Flange Electric Water Pump (12V) is a compact, high-performance cooling solution based on the proven EWP^®80 platform first introduced in 1999. Designed for naturally aspirated engines up to 2.0L (2000cc), it offers flexible installation as either a replacement or auxiliary pump.

With its flange-mounted configuration, this model provides enhanced versatility and ease of fitment across a wide range of vehicle applications.

EWP^® Installation Options

Electric Water Pumps (EWP^®) offer flexible installation methods to suit a wide range of vehicles and performance goals. Whether used to enhance an existing cooling system or fully replace a mechanical pump, an EWP^® delivers improved cooling efficiency, reduced engine load, and potential fuel savings.

Auxiliary or Replacement Installation

An EWP^® can be installed in two primary ways:

Auxiliary Pump (Recommended for simple upgrades)
Installed alongside the factory belt-driven pump, the EWP^® significantly boosts coolant flow and heat dissipation.

• A short section (approx. 100mm / 4") is removed from the lower radiator hose
• The EWP^® is inserted inline and secured
• Wired via a thermal switch or digital controller
• Can operate in conjunction with electric radiator fans

Performance benefit:
At idle, a mechanical pump typically circulates ~15 L/min. An EWP^®150 can add up to 162 L/min, dramatically improving cooling and reducing heat soak.

Upgrading to a digital controller allows the pump and fans to continue running briefly after engine shutdown, helping prevent heat damage to critical components such as the head gasket.

Disabling the Mechanical Water Pump

This method retains the original pump housing but removes its function:

• Install the EWP^® in the lower radiator hose
• Remove the factory thermostat
• Fit a shorter drive belt to bypass the pump pulley

Optional (continuous operation):

• Modify the thermostat by drilling two 3mm holes to allow constant coolant circulation
• Reinstall with a clean housing and new gasket if required

This approach offers a straightforward installation with minimal modification.

Disengaged Mechanical Water Pump (Recommended Setup)

For improved efficiency while maintaining belt routing:

• Remove the thermostat and mechanical pump impeller
• Reinstall the pump housing to act as an idler pulley
• Block any bypass passages
• Install the EWP^® in the lower radiator hose

This method reduces parasitic loss while avoiding major belt system changes.

Full Removal of Mechanical Water Pump (Ideal Setup)

For maximum performance and efficiency:

• Remove the mechanical water pump and thermostat entirely
• Install a block adapter or blanking plate (not supplied)
• Modify or replace the radiator hose to suit EWP^® installation
• Fit an appropriate belt to drive remaining accessories

This setup eliminates mechanical drag and delivers the greatest efficiency gains.

Mounting & Installation Notes

• In most installations, the EWP^® is supported by the radiator hose
• Where additional mounting is required, soft mounting is essential to minimise vibration
• Recommended mounting kits:
  • Part #8700
  • Part #8710
    (Suitable for EWP^®115, EWP^®140, and EWP^®150 models)

Key Benefits of EWP^® Systems

• Increased coolant flow and cooling performance
• Reduced engine load → improved power delivery
• Lower fuel consumption
• Improved engine protection during hot shutdown
