DIAGNOSIS AND TESTING
CHARGE AIR COOLER SYSTEM - LEAKS
Low turbocharger boost pressure and low engine per-
formance can be caused by leaks in the charge air
cooler or plumbing. Fuel staining on the exhaust man-
ifold can also be an indication that there are leaks in
the air system. The followingprocedure outlines how
to check for leaks in the charge air cooler system.
This procedure can also be used to check for leaks in
the wastegate signal line or the wastegate canister.
1. Loosen clamp and remove air inlet hose from tur-
bocharger.
2. Insert Special Tool 9022 Adapter into the turbo-
charger inlet. Tighten tool clamp to 8 Nꞏm (72 in.
lbs.).
CAUTION: Do not apply more than 138 kPa (20
psi) air pressure to the charge air cooler system,
severe damage to the charge air cooler system
may occur.
3. Connect a regulated air supply to air fitting on Tool
9022 Adapter. Set air pressure to a Maximum of
138 kPa (20 psi).
4. Using soapy water check the rubber sleeves, charge air cooler and intakemanifold for leaks.
5. Using soapy water check for leaks at the wastegate signal line, wastegate canister and wastegate command
valve.
REMOVAL
WARNING: IF THE ENGINE WAS JUST TURNED
OFF, THE AIR INTAKE SYSTEM TUBES MAY BE
HOT.
1. Disconnect the battery negative cables.
2. Discharge the A/C system (Refer to 24 - HEATING
& AIR CONDITIONING/PLUMBING - STANDARD
PROCEDURE) and remove the A/C condenser
(Refer to 24 - HEATING & AIR CONDITIONING/
PLUMBING/A/C CONDENSER - REMOVAL) (if A/C
equipped).
3. Remove the transmission auxiliary cooler (Refer to
7 - COOLING/TRANSMISSION/TRANS COOLER -
REMOVAL).
4. Remove intake air tubing from the charge air
cooler.
5. Remove the charge air cooler bolts. Pivot the
charge air cooler forward and up to remove.
