SECTION 2: OPTIONS FOR PUMP CONTROL

1. With EWP
Fan Digital Controller, Part #8000 or Part #8020:
We highly recommend the use of the EWP
cooling efficiency. The EWP
to the coolant temperature. You set the temperature desired for maximum power
or fuel efficiency. The Digital Controller has an in built function that allows the
®
EWP
to run on after hot engine shutdown to eliminate heat soak. We further
recommend the removal of the engine's thermostat and disabling of mechanical
water pump. The pump belt may need to be modified or the pump pulley left as an
idler. The vehicle's heater may take a little longer to warm up and to improve the
heating, we recommend the fitment of an Electric Booster Pump (EBP) to the
heater line if necessary.
2. With Davies, Craig Thermatic
Combine the EWP
listed here when the EWP
mechanical water pump cool an overheating engine.
Connect the thermal switch directly to the battery and your EWP
eliminate heat soak. You may leave the thermostat in place, but ensure the EWP
operates only when the thermostat is fully open.
3. Continuous running:

mechanical pump impeller or pump belt. This option may also be used for road cars
with the thermostat in place with a small hole (suggest 5mm), allowing a small
amount of flow to circulate even when the thermostat is closed.
WARNING: When using the Electric Water Pump (EWP
is recommended that an EBP be fitted to circulate coolant through the LPG
converter.
