Maintenance Instructions
Service intervals are based upon average operating conditions.
In certain environments and vocations, more frequent servicing
will be required.
Any replacement parts used for required maintenance services
or repairs should be genuine International® service parts. Use
of inferior replacement parts hinders operations of engine and
emission controls and can reduce engine life and/or jeopardize
the warranty.
Receipts covering the performance of regular maintenance
should be retained in the event questions arise concerning
maintenance.
The receipts should be transferred to each
subsequent owner of the engine (vehicle).
Engine fluids and contaminated material
GOVERNMENT REGULATION: Engine fluids
(oil, fuel, and coolant) may be a hazard to human
health and the environment.
Handle all fluids and
other contaminated materials (e.g., filters, rags) in
accordance with applicable regulations.
Recycle
or dispose of engine fluids, filters, and other
contaminated materials according to applicable
regulations.
Scheduled Maintenance
For information regarding routine scheduled maintenance such
as replacement of oil, filters, coolant, belts, belt tensioners, etc.,
and inspection and adjustment of items such as valve lash, etc.,
refer to the Engine Operation and Maintenance Manual supplied
with the vehicle.
Air Induction System
WARNING
To prevent property damage, personal injury, or
death when performing maintenance and repairs
to any turbocharged engine with engine air inlet
piping disconnected, a turbocharger compressor
air inlet protective shield should be installed over
the turbocharger air inlet. Order protective shield
J-26554 for MaxxForce® engines from your local
International dealer.
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 metal
component and inspecting for salt build-up that can cause
particles to flake off and enter the engine combustion chambers.
If evidence of corrosion is found (usually appears at the pipe
connections), use a wire brush and cloth to clean the inside of
the pipes and rubber/plastic pipes.
If the intake pipes are pitted at the joint ends, use RTV Silicone
to seal the joints. Be certain that no excess material that can be
pulled into the engine is on the inside of the pipe. If the service
condition of the pipes, hoses, or clamps is questionable, replace
those parts.
• Check for loose hoses and clamps.
