Replacing the coolant
To replace the coolant correctly:
1. Place the machine on a at surface.
2. Switch off the engine and remove the ignition key.
Place a “maintenance work in progress” sign in the cab.
3. Open and fasten the bonnet.
4. Unscrew the screws (g.26/D) to remove the bottom part
of the engine compartment (g.26/D Pos.“1”).
5. Place a suitably sized container below the radiator to
collect any coolant that may leak during the replacement
procedure.
6. Remove the lid on the bonnet (fig.25/D Pos.“1”) by un-
screwing the screws (g.25/D Pos.“2”) and remove the
ller cap (g.25/D Pos.“4”) to speed up the operation.
7. Remove the radiator hose (g.25/D Pos.“3”) to allow the
radiator water to ow out.
8. Allow the cooling circuit to empty completely.
9. Check the condition of the radiator hoses and their fit-
tings. Replace if necessary.
10. Clean the radiator by pouring clean water through the l-
ler cap (g.25/D Pos.“4”) and allow the water to drain out
through the radiator hose hole (g.25/D Pos “3”).
If necessary, add a detergent to the clean water.
11. When clean, close the drain hole by reinserting the ra-
diator sleeve (g.25/D Pos.“3”).
12. Fill the cooling system through the filler cap (fig.25/D
Pos.“4”) up to the level (3 cm below the radiator cap)
using the coolant prepared beforehand.
13. Close the cap (g.25/D Pos.“4”) and switch on the engine.
Allow the engine to idle for a few minutes.
14. Check that there are no leaks, check the level and top up
with more coolant if necessary.
15. When you have finished, re-close the lid (fig.25/D
Pos.“1”) with the screws (g.25/D Pos.“2”).
- CAUTION -
Use demineralised water to ll the cooling system.
Hard water causes scale and reduces system lifetime.
- CAUTION:
Wear appropriate protective clothing during these procedures.
- CAUTION:
Exhausted coolant is a potential danger to the environment
and must be disposed of appropriately.
- CAUTION -
The radiator must always be filled with a solution of
distilled water and antifreeze to avoid corrosion and to
prevent the water from freezing in the system.
The mixture percentages are indicated on the antifreeze
container.
