After the first change at 15.000 km (9,300 mi) lubricant oil and oil filter must be obligatory changed at
each 15.000 km (9,300 mi) or 6 months maximum (which one first occurs). Fuel filter must be replaced
and fuel tank clean (maximum) at each 6 months, even without reached the limit of 15.000 km (9,300 mi)
(recommended for the fuel filter change).

* Services that have to be made by Distributors / Authorized Services Net.

** Services that have to be made by part manufacturer.

Remark

:

 For vehicles that work predominantly in regions where sulfur index in fuel is over than
1%, lubricant oil change intervals must be at each 7.500 km.

Check the terminals and battery level.

TURBOCHARGER

The turbocharger is compound of a rotary turbine
and a air compressor, located in opposite sides
of a same shaft. The compressor and turbine
rotors are covered by housing denominated
compressor and turbine, which function is to
direct the gases flow through the rotors shovels.

These gases having energy in pressure,
temperature and speed form, cause the rotation
of the turbine rotor and consequently of the
compressor rotor.

With the rotation, the atmospheric air (that must
be properly filtrate) is aspired, and later on,
compressed to the compressor rotor from where
goes to turbocharging (in turbocharged
International HS 2.8L engines) and later on to the
engine cylinders. Having a higher pressure in the
intake, the work done by the cylinders is positive,
in other words, the cylinders spent a smaller
amount of energy in the intake.

In turbocharged International HS 2.8L engine, the
turbocharger is also composed by a Wastegate
valve or VNT, which controls the maximum
pressure to be provided by the compressor, to
avoid damages in the engine.

Other advantage:

Existing a larger mass of air, we can fire a larger
amount of fuel, besides we get a better
combustion of the mixture.

The operation of an engine equipped with
turbocharger does not require any special
procedure.

Anyway, to assure the maximum durability of the
turbocharger, take care of these items:

To accelerate the engine immediately after
starting damages the turbocharger, because it
gets a high speed without the oil flow need on its
shaft.

To accelerate the engine before stop it, also
damages the turbocharger, because it stops the
lubrication but, on the other hand, the turbo shaft
still has a high speed.

Operation and Maintenance Recommendations

INTERNATIONAL ENGINES

The intake of strange objects, even smalls, will
damage the rotor of the compressor, damaging
the operation of the turbocharger, this way,
between the recommended periods check the air
filtering system.

By working at high speeds and temperatures, the
turbo requires a lubricant oil that accomplish to
these requirements, and never should be used a
lubricant oil that does not attend to API / ACEA
specification (5th class - multi-viscous).

ACCESSORIES BELTS

If the panel of the equipment accuses high
temperature and / or battery low charge, check if
the belt is loose or ruptured.

Two belts equip the turbocharged International HS
2.8L engine. It is very important that the belts be
installed exactly as shown in the illustration.

Two tensors adjust automatically the belts
tension, eliminating this way the necessity of
individual adjustment.

The belts must be checked at each service and
replaced when necessary.

Off-road use

Belts regular checks are essential if the vehicle is
used off-road. When executing service in the
vehicle, the owner must be contacted to identify
the way in that the vehicle’s mileage has been
get.

After each off-road use, the owner must check
the belts for cuts and damages caused by
stones. If one of the belts gets loose, it must be
repositioned correctly, replacing in the next
service or before, depending on the damage
level.

Belts conditions check

Check belts conditions, replacing them if they
present waste, cracks or contamination with oil.
