IMPORTANT
●Decrease the load on the tractor:
• when the coolant temperature warning light
illuminates
●To lower the coolant temperature:
• idle the engine until the coolant temperature
warning light turns off
• shut off the engine
• allow the engine to cool down
●After the preceding actions, check the following:
• the coolant level in the radiator and in the
reserve tank are adequate
• the radiator and radiator screen are free from
dust deposits
• the alternator/fan belt tension is correct
●For details, see “Chapter 14. PERIODIC
SERVICE” on page 14-1.
●If the coolant temperature warning light
illuminates again:
• shut down the engine
• immediately contact YOUR LOCAL YANMAR
TRACTOR DEALER for technical assistance
Avoid injury!
●Before checking always allow the radiator to
cool down:
• the radiator is hot and can cause burns
• the build up pressure in the cooling system
can cause the coolant to spray out
explosively during removal of the radiator
cap
●Always shut off the engine.
●Allow the engine to cool down.
●Remove the radiator cap only when:
• the radiator and the engine are sufficiently
cooled down that can be touched with bare
hands
●When removing the radiator cap, always:
• loosen the radiator cap to the first stop
• the preceding action releases excessive
pressure on the radiator
• fully remove the radiator cap once the
pressure has been released completely
●For tractors equipped with a coolant reserve
tank:
• add coolant or water to reserve tank, not to
the radiator
