EWP & controller installation demonstration
EWP® installation options
Installing an EWP® as an AUXILIARY PUMP
- Leaving the mechanical water pump in place, install the EWP® into the bottom radiator hose.
- Remove the thermostat and drill two approx. 3mm (1/8") holes in the thermostat plate to allow some coolant circulation when the thermostat is closed. Re-install ensuring that the thermostat housing is clean and a new gasket is used if required.
EWP® installation – disabling Mechanical water pump
- Leaving the mechanical water pump in place, install the EWP® into the bottom radiator hose and remove the manufacturer’s thermostat.
- You will need to bypass the water pump pulley by installing an appropriate length belt (not supplied). This method makes for an easy installation.
- If running the pump continuously remove the thermostat and drill two approx. 3mm (1/8") holes in the thermostat plate to allow some coolant circulation. Re-install ensuring that the thermostat housing is clean and a new gasket is used if required.
In both these cases, the EWP® will pump past the impeller of the mechanical water pump.
Disengaged mechanical water pump (recommended)
- Remove the mechanical water pump and remove the thermostat.
- Then remove the impeller from the mechanical pump shaft. Retain the mechanical water pump using the pump pulley as an idler to avoid re-routing the drive belt.
- Block any bypass passages and re-install the disengaged water pump ensuring that all gasket surfaces are clean and the new gaskets are properly fitted to prevent leaks.
- Install the EWPÒ into the bottom radiator hose.
Removed mechanical water pump (Ideal)
- Remove the mechanical water pump and thermostat from the engine.
- Install a Davies Craig EWP® Header Adaptor or blanking plate (not supplied). Ensuring the gasket surfaces are clean and the appropriate gasket or sealant is used to prevent leaks.
- Install the EWP® into the bottom radiator hose. This method will require you to modify or replace the standard radiator hose.
- Install an appropriate length belt (not supplied) to drive the accessories.
In most cases EWP® will be adequately supported by the radiator hose. Where mounting is required, the EWP® must be soft mounted to protect against vibration. For the EWP®115, EWP®140 and EWP®150 Part #8700 or #8710 Mounting bracket is recommended.
