CHASSIS-MOUNTED CHARGE AIR COOLER

Inspect charge air cooler daily

With the engine off, visually inspect the charge air cooler core assembly
for debris and clogging of external fins. 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.

ELECTRICAL SYSTEM INSPECTIONS

Periodically inspect electrical connectors on the outside of the cab, on
the engine and frame for corrosion and tightness. Exposed terminals
such as the fuel sender, cranking motor, alternator and feed-through
studs should be cleaned and re-coated with a lubricant sealing grease
such as Motorcraft Silicone Brake Caliper Grease and Dielectic
Compound XG-3, or equivalent. This should include the ground cable
connector for batteries, engine and cab as well as the jump starting stud.
Accessory feed connections
Vehicle electrical systems are complex and often include electronic
components such as engine and transmission controls, instrument panels,
ABS, etc. While most systems operate on battery voltage (12 volts),
some systems can be as high as 90 volts or as low as five volts. Refer to
the Electrical Circuit Diagram Manuals, available from your vehicle's
manufacturer, to ensure that any additional body lights and accessories
are connected to circuits that are both appropriate and not overloaded.
No modification should be made to any vehicle control system without
first contacting your dealer.
