COOLING SYSTEM
WARNING
High—pressure steam and hot water.
Remove the filler cap with extreme care.
DO NOT check or fill while the engine is
hot or running.
Anti—freeze:
It is very important that you read
the label on the container before you
add anti—freeze to the cooling system.
The safety precautions are as follows:
• Keep locked up and out of reach of
children.
• Keep only in the original container.
• Avoid contact with the skin and
eyes.
• Wear suitable protective clothing
and gloves.
• Harmful by inhalation and if swal -
lowed.
• If swallowed, seek medical advice
immediately and show the label or
container.
Coolant
Check the radiator coolant level —
Flexible maintenance.
DO NOT use an anti-freeze solution for
more than two years (or 2000 hours) of
operation. The heat generated by the die-
sel engine causes a natural change in the
inhibitors in the coolant which results in
loss of corrosion protection. The loss of
the inhibitors may cause water pump cavi-
tation and cylinder block erosion.
1. To check the coolant level first remove
the radiator cap slowly to allow pres-
sure to escape. DO NOT add cold cool-
ant to a hot system.
2. The coolant level must be maintained
at 25 mm (1 in) below the filler neck.
Top up with anti-freeze solution of the
correct strength.
Drain the cooling system every 1000
hours or two years whichever is the
sooner.
1. To drain the cooling system remove
the radiator cap slowly to allow any
pressure to escape.
2. Remove the drain plug at the bottom of
the radiator (Fig. 22).
