Inspections and maintenance
– When cleaning the radiator or intercooler, make sure not to damage the fins.
– Do not direct the high-pressure cleaner or steam cleaner jet at the air conditioning
system condenser for too long. As a result of the high temperature, the pressure in
the system rises too high, which may damage the system. Parts of the air
conditioning must not be cleaned with the aid of a high-pressure or steam cleaner
as this can damage the seals.
– Do not pressure clean a hot exhaust system.
– Under no circumstances direct the cleaning nozzle into or around the exhaust
opening (diffuser).
The Emission Aftertreatment System is equipped with sensors which monitor
engine emissions, these sensors are sensitive to moisture and or water.
When a vehicle is high pressure cleaned, there is a risk that water can enter the
exhaust system, reaching these sensors and irreversibly damage these sensors.
Therefore caution must be exercised whilst high pressures cleaning the vehicle.
Avoid the hot exhaust system and not direct the cleaning nozzle into or around the
diffuser. Equally, if the vehicle must be cleaned in a drive through wash, the exhaust
diffuser must be shielded to prevent exhaust system water ingress.
NOTE: To, be absolute sure cover the diffuser when using a high-
pressure cleaner or steam cleaner in that area.
– Make sure that no water can enter the differential and gearbox via the vents.
– Make sure that no water can enter via the reservoir bleed screws of the clutch,
trailing axle and so on.
– The engine and engine compartment can be cleaned with a high-pressure or steam
cleaner. Do not spray directly onto electrical components such as the fuel system
components, electronic control units, starter motor, alternator, air conditioning
compressor, headlights and so on.
Directly after the cleaning process, the
engine must run (at idle or driving) for at least 15 minutes.
– Carefully clean the engine encapsulation and its fittings. Remove any spilt oil and
diesel oil to avoid the risk of fire.
– Do not aim the jet of water directly at electrical connectors.
– Do not aim the jet at the gear change lever unit.
– Do not aim the jet at the head- and fog light lenses.
– When cleaning the vehicle, make sure that no water can enter the air inlet system
via the air inlet or its flexible seals.
– When the vehicle has been cleaned, lubricate it with a grease gun or via the
automatic lubrication system. This is important because it prevents the penetration
of moisture and dirt at the various pivot points.
Cleaning the cabin interior
The plastic panels can be cleaned with a household cleaning agent and warm water.
The fabric trimming must be cleaned with a non-aggressive dry-cleaning agent or an
equivalent product. Leather trimming must be cleaned with leather cleaning solution
and treated with leather conditioner.
