B. Aftercooler Water Pump Wiring And
Installation
1.
Mount the aftercooler pump relay in the loca-
tion shown in Fig. 11-f using the supplied sheet
metal screw.
2.
Connect the yellow wire from terminal #85 to
the black wire with yellow stripe running from
the coil using the supplied wiretap.
3.
Run the black wire from terminal #86 on the
aftercooler pump relay to the battery chassis
ground located on the passenger side strut
tower in front of the fuse box.
4.
Connect the red 12-gauge wire from terminal
#30 on the aftercooler pump relay to the fuse
holder using the supplied butt connector.
Install a yellow ring terminal on the other end
of the fuse holder and bolt to one of the two
fuse box power supply wires at the front of the
fuse box (see Fig. 11-f).
5.
Install the supplied water pump clamp on the
water pump. Insert a 1/2” long screw through
the clamp and tighten in the position shown
in Fig. 11-c. The pump outlet should poing
toward the driver’s side of the vehicle with
room to route the hose in front of the radiator
core support.
6.
Use the supplied black wire, ring terminal and
slide connectors to extend the water pump
ground wire (brown wire on Hella pump) to the
same grounding location used for the water
pump and fuel pump relay grounds.
7.
Route the red wire from the aftercooler relay
terminal #87 to the water pump. Using the
supplied male and female slide connectors,
attach the red wire to the positive wire on the
water pump (green wire on Hella pump).
8.
Using thread sealant, install a 1/2” NPT 90° hose
barb fitting in the bottom of the aftercooler
reservoir so that it points towards the water
pump inlet.
9.
Loosen the water pump clamp bolt and con-
nect the pump inlet to the bottom reservoir
fitting with the supplied 90° hose. Secure the
hose with nylon clamps on both ends. Tighten
