Radiator
Fig.199: Radiator in engine com-
partment
A combination radiator is located in the engine compartment. It consists
of several parts. One part cools the hydraulic oil, the second part is inten-
ded for engine cooling and possibly another part cools the combustion air
of the engine.
If the vehicle becomes too hot during prolonged operation or high outside
temperatures, check the following points.
• Is there sufficient coolant in the radiator?
• Has the mixing ratio of the coolant been observed?
• Are the radiators and the spaces between the radiator fins clean and
not blocked?
• Are all seals fitted around the radiator?
• Is the fan belt tensioned and in good condition?
• Does the fan drive oil motor work?

► The higher the dust content in the circulating air, the more frequently
all radiators must be checked and cleaned.
► Always cover up the intake connection of the air filter before clean-
ing.
► Do not damage the fins when cleaning the radiator.
► Carefully straighten bent fins.
Environment
Avoid environmental damage!
► Clean the vehicle in a suitable place where the dirty waste water can
be collected in an environmentally friendly manner.
