Chassis-mounted Charge Air Cooler
Visually inspect the core assembly for debris and clogging of external fins
with the engine off. Prior to engine operation, remove any debris
blocking the core.
• Turbocharger-to-charge air cooler
• Charge air cooler-to-intake manifold pipe
• Mounting bracket
• Chassis-mounted charge air cooler core
Inspect air intake piping:
• Check for accumulation of salt deposits (where applicable).
If present, disassemble and clean the complete air intake piping
system. If the intake piping is pitted, use Motorcraft® Silicone Gasket
and Sealant TA-30 to seal joints against leakage.
• Check for loose hoses and clamps.
• Check for ruptured or collapsed hoses.
• Check air cleaner housing for cracks.
Suspension Inspection
Note: Do not adjust air suspension height to any setting other than the
specified setting. Altering the height setting changes the driveline angle
and may result in unwarrantable component damage, such as
transmission component damage.
Verify drive axle air suspension height and height control valve
performance at engine oil change intervals.
Periodically check:
• Condition of spring leaves for evidence of fatigue, bending or
breakage.
• Condition of suspension mounting brackets and bushings.
• Torque rod mounting fasteners for tightness.
• For proper suspension alignment. This must be maintained at all
times.
• U-bolts. After the chassis has been operating under load for
1000 miles (1600 kilometers) or six months (whichever comes first),
the U-bolt nuts must be re-torqued. The U-bolt nuts must be
re-torqued every 36000 miles (60000 kilometers) thereafter. The
U-bolt and nut threads and seats should be cleaned and lubricated to
make sure a like new condition when re-torquing.
Note: See Spring U-bolt check later in this chapter.
