Maintenance Instructions
Accessory Feed Connections
WARNING
To prevent property damage, personal injury, and
/ or death, do not increase size of fuse or circuit
breaker or change type of breaker supplied
with your truck, as this could cause wiring to
overheat and possibly burn. Electrical circuits
are designed with a particular wire gauge to meet
the fuse and circuit breaker current rating.
Vehicle electrical systems are complex and often include
electronic components, such as engine and transmission
controls, instrument panels, and antilock brakes. While most
systems still operate on battery voltage (12 volts), some
systems can be as high as 90 volts or as low as 5 volts.
Refer to the Electrical Circuit Diagram manuals, available from
your International dealer, to ensure that any 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 International
dealer.
Fuses and Relays
Fuses and relays are located inside the cab within the fuse
panel cover.
Refer to the schematic located on the fuse
panel cover in the cab, the schematic on the fuse cover in
the luggage compartment, or the
Fuse Panel Schematic
located in SECTION 8 — MAINTENANCE INTERVALS AND
SPECIFICATIONS of this manual for fuse or relay replacement.
Engine
General Information
NOTE: For complete operation and maintenance
information pertaining to your engine, refer to the Engine
Operation and Maintenance Manual provided with the
vehicle.
For effective emission control and low operating cost, it is
important that maintenance operations be performed at the
specified periods or mileage intervals indicated in the Engine
Operation and Maintenance Manual.
Service intervals are based on average operating conditions. In
certain environments and locations, more frequent servicing will
be required.
The required maintenance operations may be performed at a
service establishment. Any replacement parts used for required
maintenance services or repairs should be genuine OEM service
parts. Use of inferior replacement parts hinders operation 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).
