Low turbocharger boost pressure and low engine
performance can be caused by leaks in the charge air
cooler or it's plumbing. The following procedure out-
lines how to check for leaks in the charge air cooler
system.
(1) Loosen clamp and remove turbocharger to air
inlet duct rubber sleeve from turbocharger.
(2) Insert Special Tool 8442 Adapter into the rub-
ber sleeve. Tighten existing clamp to 8 N´m (72
in.lbs.).
CAUTION: Do not apply more than 138 kpa (20 psi)
air pressure to the charge air cooler system, sever
damage to the charge air cooler system may occur.
(3) Connect regulated air supply to air fitting on
Special Tool 8442 Adapter. Set air pressure to a Max-
imum of 138 kpa (20 psi).
(4) Using soapy water check the air inlet ducts,
rubber sleeves, charge air cooler and intake manifold
for leaks.
REMOVAL
(1) Remove front bumper.
(2) Remove headlamp assemblies.
(3) Remove front cross member together with front
grille.
(4) Remove left and right radiator trim (Fig. 3).
(5) Disconnect charge air hoses at charge air cooler
(Fig. 3).
(6) Disconnect power steering cooler loop from
charge air cooler (Fig. 3).
(7) Remove charge air cooler from radiator assem-
bly (Fig. 3).
CLEANING
CAUTION: Do not use caustic cleaners to clean the
charge air cooler. Damage to the charge air cooler
will result.
NOTE: If internal debris cannot be removed from
the cooler, the charge air cooler MUST be replaced.
(1) If the engine experiences a turbocharger failure
or any other situation where oil or debris get into the
charge air cooler, the charge air cooler must be
cleaned internally.
(2) Position the charge air cooler so the inlet and
outlet tubes are vertical.
(3) Flush the cooler internally with solvent in the
direction opposite of normal air flow.
(4) Shake the cooler and lightly tap on the end
tanks with a rubber mallet to dislodge trapped
debris.(5) Continue flushing until all debris or oil are
removed.
(6) Rinse the cooler with hot soapy water to
remove any remaining solvent.
(7) Rinse thoroughly with clean water and blow
dry with compressed air.
INSPECTION
Visually inspect the charge air cooler for cracks,
holes, or damage. Inspect the tubes, fins, and welds
for tears, breaks, or other damage. Replace the
charge air cooler if damage is found.
Pressure test the charge air cooler, using Charge
Air Cooler Tester Kit.
INSTALLATION
(1) Install charge air cooler to radiator (Fig. 3).
(2) Connect power steering cooler loop to charge
air cooler (Fig. 3).
(3) Connect charge air hoses (Fig. 3).
(4) Install both radiator trim pieces (Fig. 3).
(5) Install front grille with front cross member.
(6) Install headlamp assemblies.
(7) Install front bumper.
