first.
1. If hose clamps are loose or water leaks, tighten hose
clamp securely.
2. Replace hoses and tighten hose clamps securely, if
radiator hoses are swollen, hardened or cracked.
BPrecaution at overheating
The event that the coolant temperature is nearly or more
than the boiling point is called "OVERHEATING".
While running, make the following checks to see that all
parts are working correctly. If anything is unusual,
inspect it, referring to the relevant description in.
"MAINTENANCE".
C Coolant
If the coolant temperature warning lamp lights up or if
steam or coolant does not stop squirting from the radiator
overflow pipe, turn off the load and keep the engine
idling (COOLING-DOWN) for at least 5 minutes to let it
cool down gradually. Then stop the engine and take the
following inspection and servicing.
1. Check to see if the coolant runs short or if there is any
coolant leak;
2. Check to see if there is any obstacle around the
cooling air inlet or outlet;
3. Check to see if there is any dirt or dust between
radiator fins and tube;
4. Check to see if the fan belt is too loose; and
5. Check to see if radiator water pipe is clogged.
