18.A ESCALADE/DENALI/SS CHARGE COOLER HOSE ROUTING
B. Cut a 36.5" length of 3/4" hose. Run it
from the bottom fitting on the surge
tank along the fender toward the front
and down to the 90° brass fitting on the
top of the water reservoir.
C. Take the supplied 4" x 12" 90° molded
elbow and cut 1-3/4" from the 4.0" end.
Connect the trimmed end to the straight
brass fitting on the charge air cooler.
Route the long end toward the surge
tank. Cut a 110" length of hose and
connect it to the end of the installed
molded elbow with the supplied 3/4"
union. Route the hose along the fender-
well, down toward the water reservoir
and up under the front bumper. There is
a small opening in the rubber apron
between the bumper and A/C condens-
er. Pull the hose up and through, then
connect it to the driver’s side 90° fitting.
D. Cut a 64" length of 3/4" hose. Run it
from the outlet of the water pump to the
same hole in the rubber apron you
pulled the previous hose through. Pull
the hose up and through, then connect
it to the passenger’s side 90° fitting.
E. Secure all hose ends with the supplied
nylon clamps.
F. 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 neces-
sary, provide light suction to the hose to
help prime the pump. Verify water flow.
Do not let the pump run for extended
periods (30 seconds or more) without
water flow. Fill the charge cooler tank
until the level stabilizes.
Fig. 18.A-a
NOTE: When routing hoses, refer to Fig. 18.A-a.
NOTE: Make sure to leave the hose slightly
long to allow for engine movement.
A. Cut a 13.5" length of 3/4" hose. Run
this from the 90° fitting on the charge
air cooler to the straight brass fitting on
the surge tank.
