115 INSTALLATION INSTRUCTIONS
DAVIES, CRAIG EWP
®
(ELECTRIC WATER PUMP) AND OPTIONS FOR PUMP CONTROL
Congratulations on your purchase of the Davies, Craig EWP
®
which is designed to replace or supplement the
existing belt driven mechanical water pump of your engine. Your EWP has very high flow capacity and has the
advantage of running at a speed independent of the engine speed. The EWP
®
can also be set to continue running
after a hot engine shut down to prevent damaging heat soak. When your EWP
®
is used to replace the
mechanical pump, you will notice an increase in engine power and torque, especially at high engine speeds.
Automatic gear changes, both up and down, will be smoother.
PLEASE READ THESE INSTRUCTIONS IN THEIR ENTIRETY BEFORE YOU START WORK
ALSO NOTE THAT THE EWP IS A ‘CIRCULATION’ PUMP IDEAL FOR ‘CLOSED CIRCUIT’ OPERATION SIMILAR
TO AN AUTOMOTIVE COOLING SYSTEM. IT IS NOT A ‘SELF-PRIMING’ PUMP AND THEREFORE WILL NOT
OPERATE WITHOUT A POSITIVE ‘HEAD’ IN AN ‘OPEN’ SYSTEM.

SECTION ONE: INSTALLING THE EWP
®
115
1.
The EWP
®
115 is best fitted in the lower radiator hose connecting the radiator to the existing mechanical
water pump housing and let the hose hold the weight of the pump and it will dampen from vibration too.
Check the area for available space and shape of the hose. The section of radiator hose connected to the
radiator must be connected to the inlet of the electric pump and the section of radiator hose connected to the
original pump/engine block must be connected to the outlet of the electric water pump. The pump inlet is in
the centre of the pump. The EWP
®
should be positioned as low as possible to maximise the gravity feed
from the radiator and prevent air entering the pump. Alternatively, it can be fitted in the upper hose, but in
this case the coolant level must be maintained and now the section of radiator hose connected to the top of
the radiator must be connected to the outlet of the electric pump and the section of radiator hose connected
