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.
