Checking / topping up engine coolant
Prior to checking coolant level, allow engine to
cool. The proportion of antifreeze in the engine
coolant must not exceed 50 percent.
– Raise the debris container.
– Check coolant level in expansion tank.
– With engine cold, top up engine coolant to the
"min" mark in expansion tank.
Checking cooling system for leaks
The radiator is a combination of two cooling
circuits, one for hydraulic fluid, the other for engine
coolant. The fan transports the cooling air from
the outside into the engine compartment, passing
it through the dual-circuit radiator. Check all
radiator hoses, connections and the radiator itself
for leaks.
Checking cooling fan functions
The fan must start as soon as the ignition key
is turned to position "1".
– Check electrical connections and fuses,
and replace as required.
– Measure voltage applied to electric motor.
– If required, replace connecting cable / relay
/ electric motor.
When replacing the fan, it must be noted that the
cable inlet connection on the electric motor points
downward.
