ENGINE RADIATOR
(Fig.22/D Pos.“1”)
- CAUTION -
These procedures must be carried out when the engine is cold.
Cleaning the radiator grille
The radiator grille (fig.22/D Pos.“2”) must be kept as clean
as possible to allow the best heat exchange between the
radiator and the air circulating around it. To remove impurities
use a jet of low pressure air from outside in towards the ra-
diator (that is from the air outlet towards the engine (g.22/D).
Then blow the jet of air over the parts inside the engine
compartment that come in contact with dirt. Clean the gap
between the radiator and the air intake (g.22/D Pos.“3”) with
a cloth. If the dirt has become particularly compact, it is advi-
sable to loosen it with a jet of water at low pressure from insi-
de the engine compartment outwards before using the air jet.
- CAUTION:
Before subjecting the engine to jets of air or water, consult
the relative use and maintenance manual.
- CAUTION:
The heat exchanging ns are very delicate, do not clean with
cloths or brushes. Water and air jets must be aimed horizontally.
Checking the coolant level.
During normal machine use, the water level must be kept 3
cm below the radiator cap (g. 23/D Pos. “1”).
To ensure the coolant level is correct, proceed as follows:
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. Remove the lid on the bonnet (fig.24/D Pos.“1”) by un-
screwing the screws (fig.24/D Pos.“2”) and access the
radiator cap (g.24/D Pos. 3”).
4. Slowly unscrew the radiator cap (g.24/D Pos.“3”)
anticlockwise until you reach the safety limit stop.
5. Release the pressure and steam.
6. Remove the cap.
7. Check the coolant level. If necessary top up by introdu-
cing a mixture of water and antifreeze.
8. Reverse the procedure to reinstall the cap.
- CAUTION:
If it is necessary to top up the radiator frequently in normal
working conditions, ensure there are no leaks in the cooling sy-
stem. If there are any problems, contact a DIECI service centre.
- CAUTION:
Use demineralised water to top up the cooling system.
Hard water causes scale and reduces the system life span.
