Catalytic Converter (Diesel Engine)
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.
If your diesel engine is equipped with a catalytic converter, it is
important to review the maintenance schedule to make sure proper
functioning of the catalytic converter. Also, take precautions not to
damage the catalytic converter when servicing your engine or storing
your vehicle.
Diesel Exhaust Fluid (DEF), Diesel Particulate Filter (DPF) and
Select Catalyst Reduction (SCR) System
See your engine operator's manual for information regarding DEF, DPF
and SCR system service.
Air Induction System
WARNING: 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.
Perform a complete inspection of the air induction system annually.
In areas where road salt is used, disassemble the joints of each aluminum
component and inspect for salt build-up and 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. Make sure 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).
Make sure all dust and debris has been cleaned out of the pipes and
couplings with a clean, damp rag prior to reassembly.
