2. Turn off the engine, by turning the ignition key (24, Fig. D) counterclockwise, to the end of stroke, then remove it.
3. With a suitable ladder, reach the coolant tank (43, Fig. F).
WARNING!
The coolant line is pressurised; do not perform any check until the engine has cooled down and, even if the
engine is cold, the plug (2, Fig. AR) of the tank (1) must be opened with extreme care.
4. Check that the coolant level in the tank (1, Fig. AR) is between the minimum and maximum marks, as shown in the diesel
engine Manual. If necessary, unscrew the plug (2) and top up.
Coolant components:
• 50% of AGIP antifreeze
• 50% of water
