E. Run the black wire from terminal #86 on the
water pump relay to ground (see Fig. 13-d)
F. With the long red 12-gauge wire connected to
the water pump relay terminal #87, route the
free end down along the fenderwell and under
the base of the radiator over to the positive
(blue/green) wire on the water pump. Secure
as necessary to avoid heat and sharp edges
(see Fig. 13-e).
G. Run the negative (brown) wire from the water
pump to a clean ground.
H. With the key on, make sure the charge cooler
water pump is operating and that water is
flowing through the surge tank. Fill the surge
tank if necessary. If the water is not flowing,
remove the charge cooler supply hose and
lower until water flows out of the hose. If nec-
essary, provide light suction to the hose to
help prime the pump. Verify water flow. Do not
let the pump run for extended periods (30 sec-
onds or more) without water flow. Fill the
charge cooler tank until the level stabilizes.
