7.2 FLUSHING COOLING SYSTEM

}

In order to avoid damaging the

cylinder block, do not top up a warm

engine with cold coolant. Coolant is

a toxic fluid and must be handled

with care. Protect skin and eyes.

Coolant is harmful to the

environment; after use, it should be

processed as industrial chemical

waste. When the coolant is hot, there

is overpressure in the cooling

system. When removing the filler

cap, allow the overpressure to

escape by first loosening the filler

cap one turn.

1.

Drain the cooling system at the cylinder

block via the drain tap (A), the radiator via

drain plug B and the oil cooler via plug C. If

an integrated retarder is fitted, remove the

coolant drain plug of the heat exchanger.

2.

Flush the cooling system.

3.

Close the drain cock (A) and fit drain plug B

and, if applicable, the coolant drain plug of

the heat exchanger of the integrated

retarder.

4.

Fill the cooling system.

5.

Check the coolant level.
