This machine's radiator has a surge tank. There is no top tank in this cooling system. The surge tank has a filler cap and a sight glass. It is not necessary to remove the filler cap in order to check the coolant level. The sight glass is inside the engine compartment on the front left side of the machine. The filler cap is beneath access door (1) that is on the top left side of the radiator guard.

Observe the sight glass in order to verify the level of the coolant. If the coolant completely covers the sight glass, the coolant level is okay. If the coolant level is visible in the sight glass, the coolant is low.
If it is necessary to add coolant, remove the radiator cap slowly in order to relieve the pressure.
Fill the cooling system to the bottom of the filler tube. Adding coolant above the bottom of the filler tube will cause the coolant to overflow the cooling system.
Maintain the coolant level between the top of the sight glass and the bottom of the filler tube. If you need to add coolant daily, check the cooling system for leaks.
Inspect the radiator cap and the radiator cap seal for debris, for foreign material, or for damage. Clean the radiator cap with a clean cloth. Replace the radiator cap if the radiator cap is damaged.
Install the radiator cap.
Inspect the radiator core for debris. Clean the radiator core, if necessary.Use compressed air, high pressure water, or steam to remove dust and debris from the radiator core. However, the use of compressed air is preferred.
