Beware of overheating
The event in which the temperature of the coolant approaches or exceeds the
boiling point is called "OVERHEATING".
During operation, perform the following checks to verify that all parts are
working properly. If there is anything unusual, carry out the inspection
referring to the relative description given in the "MAINTENANCE" and
"PERIODIC MAINTENANCE" section.
6.2.13.3.4 Coolant
If the coolant temperature warning light comes on, or if the steam or coolant
continues to escape from the radiator hose or cap, stop loading and keep the
engine idling (COOLING) for at least 5 minutes to allow its gradual cooling.
Then stop the engine and perform the following inspection and maintenance.
1. Check to see if the coolant is absent or if any coolant leak is present;
2. Check that the cooling air inlet or outlet is not blocked;
3. Check that there is no dust or dirt between the cooling fin and its pipe;
4. Check to see if the ventilation belt is too loose;
5. Check to see if the radiator water pipe is blocked.
6.2.13.3.5 Radiator cleaning (outdoors)
If dust is deposited between the tube fin, wash it under running water.
IMPORTANT:
• Do not clean the radiator with solid tools such as spatulas or screwdrivers. These could
damage the fin or pipe in question, and this could result in coolant leakage or decreased
cooling capacity.
6.2.13.3.6 Radiator cleaning (internal)
1. Clean the inside of the coolant line in the following cases:
• As shown in the PERIODICITY OF MAINTENANCE list;
• When the coolant is replaced.
2. Use a radiator cleaning agent. This helps to eliminate deposits of encrustations.
