TURBOCHARGER SERVICE
TURBOCHARGER INSPECTION
Conditions that warrant turbocharger inspection:
• Decreased horsepower and performance
• Slower response and power delivery (sluggish or
“laggy” feel)
• Audible noise from turbocharger
• Blue smoke emitted from exhaust
IMPORTANT
It is recommended that the air intake filter and pre-filter
be inspected daily.
CAUTION
A clogged or restrictive air filter or intake tract can
cause excessive turbocharger speeds and premature
wear.
1. Remove the exhaust pipe. See Exhaust Pipe
Removal page 3.16 outlined in this chapter.
2. Disengage five air box cover latches and remove the
air filter.
3. Inspect air filter and the inside of the air box for dirt or
foreign debris. If filter is found to be clogged, replace
the filter.
4. Remove turbocharger oil drain hose and inspect. If
the inner diameter has been deformed or obstructed,
or if any kinking or cracking is present, replace the
hose.
NOTICE
Ensure the oil drain hose located between the
turbocharger and oil pan is not kinked or obstructed in
any way.
5. Inspect for any oil seepage or leaking from either end
of the oil drain hose. Check tightness and condition of
both hose spring clamps
