Engine cooling system - Check
WARNING
Burn hazard!
Hot coolant can spray and scald if you remove the radiator or deaeration tank cap while the system
is hot. To remove the cap: allow the system to cool, turn the cap to the first notch, and wait for all
pressure to release. Remove the cap only after all pressure has released.
Failure to comply could result in death or serious injury.

Cooling system
The tractor engine must operate at the correct temperature to obtain maximum efficiency and service life. This is
dependent on the cooling system.
Only check the cooling system when the engine is “OFF” and the cooling system is cool. Never add coolant to a
hot cooling system. Never remove the radiator cap when the cooling system is hot.
Always fill the system with a 50/50 solution of

antifreeze and water.
NOTE: Your tractor was shipped with conventional ethylene glycol coolant. If you wish to change to a different
coolant type see page 7-2 .
Checking the coolant level
1. Only check the coolant level when the engine is cold.
2. Visually inspect the coolant level in the coolant recov-
ery tank (1) . The coolant level should be at the full mark
on the tank.
3. If the coolant level is below the full mark, add a 50/50
antifreeze/water solution as necessary, to the recovery
tank.
NOTICE: The cooling system already contains antifreeze,
add only an antifreeze solution of the correct water/an-
tifreeze mixture. Pure water will dilute the solution and
weaken its protection.
4. If there is not coolant in the coolant recovery reservoir
remove the cap (2) from the radiator.
5. Add enough coolant to the radiator so the coolant level
is even with the bottom of the filler neck.
6. Install the radiator cap.
