SECTION 1: INSTALLING YOUR EWP
1.
Your EWP
Electric Water Pump is best fitted in the lower radiator hose which
®
connects the radiator to the existing mechanical water pump housing. In
conventional vehicle operating conditions, the hose will carry the weight of your
EWP
and insulate the EWP
®
space. Further radiator hose or adaptors may be required. Position the EWP
the lower hose so the inlet, in the centre of the pump is connected to the radiator
side and the outlet is connected to the engine's mechanical water pump housing
or your EWP
®
low as possible to maximise the gravity feed from the radiator and to avoid air
entering and remaining in the pump.
Alternatively, the EWP
coolant level is critical and bleeding of all air from the cooling system essential.
Follow instructions above for correct EWP
connected to the hose going into the top of the radiator. The pump can be
installed in any orientation but to assist air bleeding try to mount the outlet
pointing upwards. (See Section 8 for bleeding instructions). Ensure your cooling
system is kept full of coolant.
2. If you have either an EWP130 or EWP80, assemble the provided EWP Straight and
L Adaptors to suit the configuration and space available. Ensure that the Straight
and L Adaptors have the O-Ring fit securely between them and the flange faces on
the EWP body. Six of the shorter Adaptor M5 Bolts (Part # 8507) should be used
to attach the Adaptor to the EWP outlet. The remainder M5 bolts (Part # 8507 for
EWP130) or (Part # 8514 for EWP80) can be used to attach the Adaptor to the
EWP Inlet.
If necessary, add the rubber sleeves to the inlet and outlet of the EWP
your particular hose diameter. If you require thicker sleeves, contact Davies, Craig
for supply free of charge.
3. Cut out the not required section of the radiator hose. Connect the pump inlet and
outlets to the appropriate hose ensuring hose clamps are very firmly tightened.
from engine vibration. Check the area for available
®
Header Adaptor (not supplied). The EWP
may be fitted in the upper radiator hose. In this case,
®
®
should be positioned as
®
fitment ensuring the pump outlet is
®
in
®
®
to suit
