Replacing the coolant

Drain the coolant only when the engine is cold.
Total cooling system capacity:

Open the engine compartment cover (page 74).

Open the engine compartment cover under the operator's
seat (page 76).

Open the radiator cap (1).

Open the central coolant drain plug (1) and drain the cool-
ant completely.
Fill the coolant in a container and dispose of it in
accordance with the prevailing environmental pro-
tection regulations.
Purge the cooling system if the coolant is very dirty. To do this,
spray water without additives into the cooling system with a
hose through the filler opening until clear water emerges at the
outlet.

Remove the coolant expansion reservoir (1) and drain it,
cleaning it if necessary. Refit the reservoir.

Fill the premixed coolant into the radiator and expansion
reservoir.
Do not operate the cooling system with pure water

corrosion inhibitor.

Let the engine idle for about 5 min, shut it off and check the coolant level in the radiator. The coolant
should reach the MAX. mark; if not, add coolant.

Close the engine compartment covers.
