126 Maintenance
Turbo and Charge Air Cooler
General
Do not remove, attach or tighten tur-
bocharger air intake ducting while the
engine is operating, or operate the engine
while the ducting is removed. Working
around the turbo with the ducting re-
moved may cause severe personal injury.
Visually inspect turbo mountings, intake
and exhaust ducting and connections for
leaks on a daily basis. Check oil inlet and
outlet for leaks or signs of restrictions to
oil flow. Check for unusual noise or vibra-
tion. If any faults are detected, do not
operate the engine until the cause is deter-
mined and repaired.
If oil leaks internally from the tur-
bocharger to the engine intake, the oil
acts as a fuel. Watch for excessive ex-
haust smoke. Do not operate engine until
problem is corrected. There is no way to
regulate the engine speed if it runs on
oil and it may overspeed. Loss of con-
trol of vehicle may lead to an accident
causing severe personal injury or death.
Periodically inspect the front of the
radiator/charge-air-cooler package for
buildup of dirt, mud, insects, etc. Over
time, there may be a build-up of dirt, mud,
insects, etc., between the radiator and
charge-air-cooler. Inspect for build-up and
remove the cooler package to clean, if
necessary.
