AIR SUSPENSION (IF EQUIPPED)
Note:
The vehicle must not be operated without air in the suspension
springs. Operating the vehicle without air in the suspension springs damages
the suspension, degrades ride performance and may cause property damage.
The air suspension system automatically adjusts to different loads to
maintain a constant frame height, allows for ease of vehicle loading and
provides improved vehicle ride and increased driver comfort.
Air Suspension Dump Switch
Note:The suspension dumps air when the ignition is in the accessory or
on position, but fills only when the ignition is in the on position.
The system is controlled by a switch
located in the overhead switch
pack. It operates only when the
ignition is in the accessory or on
position and the air tanks have
sufficient pressure to fill the air
springs. When the ignition is turned
off, the suspension remains in
whatever state it was last set.
Pressing the lower portion of the switch exhausts air from the air
springs, lowering the frame for loading. Pressing the upper portion of the
switch fills the air springs so the vehicle remains at normal ride height.
System Indicator Light
The air suspension indicator light illuminates when the switch
has been activated to release air pressure in the rear air shocks.
Never drive the vehicle when the warning lamp is illuminated
and there is low (or no) air pressure in the shocks.
Connecting and Disconnecting a Trailer with Air Suspension and
Air Suspension Dump Switch
When connecting to a trailer:
•Press the lower portion of the switch to exhaust air from the air
suspension system.
•Press the upper portion of the switch, then raise the landing gear
after making the connection to the trailer.
When disconnecting the trailer:
•Lower the landing gear, then press the lower portion of the switch.
•Disconnect the brake hoses, trailer-side and rear light connectors,
then pull the release lever on the fifth-wheel.

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:SeeSpring U-bolt checklater in this chapter.
