Congratulations on your purchase of the Davies, Craig EWP
®
Electric Water Pump Kit
which is designed to replace or complement the existing belt driven mechanical water
pump. In addition with a Davies, Craig Digital Controller your thermostat can be
replaced. The major benefits of an Electric Water Pump (EWP
®
) are, removal of the
parasitic power losses running a mechanical water pump at
any speed, reduction of
engine warm-up time and elimination of heat soak by running the EWP
®
after a hot
engine shut down by operating the EWP
®
with the EWP/Fan Digital Controller, or one
of the Davies, Craig Thermatic
®
Switches. Your new EWP
®
has the advantage of
providing the best coolant flow rate independent of engine speed.
