functioning of the catalytic converter. Also, take precautions not to
damage the catalytic converter when servicing your engine or storing
your vehicle.
Note: If your vehicle is equipped with a catalytic converter/muffler, do
not blend waste oil with Diesel fuel. Operate only on ultra low sulfur
(less than 15 parts per million sulfur) diesel fuel with a cetane value of
45 or higher.
Air induction system
Once each year, perform a complete inspection of the air induction
system. In areas where road salt is used, the inspection consists of
disassembling the joints of each aluminum component and inspecting for
salt build-up, presence of chlorine that can cause aluminum particles to
flake off and enter the engine combustion chambers.
If evidence of corrosion is found (usually at the pipe connections), use a
wire brush to clean the inside of the pipes and inside the rubber hoses.
If the intake pipes are pitted at the joint ends, use Motorcraft Silicone
Gasket and Sealant TA-30 to seal the joints. Be certain that no excess
material is on the inside of the pipes that can be pulled into the engine.
If the service condition of the pipes, hoses or clamps is questionable,
replace the defective part(s).
Be sure that prior to reassembly all dust and debris has been cleaned out
of the pipes and couplings with a clean, damp rag.
When performing maintenance to any turbocharged engine with
engine air inlet piping disconnected, keep loose clothing, jewelry
and long hair away from the engine air inlet piping. A turbocharger
compressor air inlet protective shield should be installed over the
turbocharger air inlet to reduce the risk of personal injury or death.
Steering - general inspection
• Ask your service technician to examine the steering mechanism. Only
minor adjustments may be necessary.
• Check tie rod, drag link end clamp bolts and ball joints. They must be
tight.
• Check for installation and spread of cotter pins and tightness of nuts
at both ends of the tie rod and drag link.
• Check that pitman arm (steering arm at steering gear) mounting is
tight and locked. Check system for leaks or hose chafing. Repair at
once.
