Changing the Coolant
The anti freeze and water coolant solution should be changed every year. The cooling system capacity is approximately 2.4 gallons.
WARNING: It is dangerous to remove the radiator cap when the system is hot. Allow the system to cool before removing the radiator cap.
•Locate the radiator drain cock on the right side od the front axle frame. Place a suitable container beneath the drain cock. See Figure 67.

•Open the radiator drain cock and remove the radiator cap. The radiator cap must be removed to completely drain the radiator.
•Close the radiator drain cock.
•Slowly pour coolant mixture into the filler neck of the radiator until the level reaches the bottom of the filler neck overflow flange.
•Wait a few minutes to allow as much air as possible to escape through the filler neck, then reinstall the radiator cap.
•Fill the overflow reservoir to the "FULL" mark.
•Start the engine and allow it to run for a short period. Stop the engine.
•Recheck the coolant level in the overflow reservoir and refill as needed. Reinstall the reservoir cap.
Dispose of used coolant in an environmen- tally safe manner. If necessary, contact your area EPA office for proper disposal proce- dures and recycling center locations.
Checking the Radiator Hoses
Check the condition of the radiator hoses and the tightness of the hose clamps every 150 hours of operation. Replace a damaged hose and tighten the hose clamps if loose. See Figure 68.
It is recommended that the hoses and, if necessary, the hose clamps be changed every two years.

LUBRICATING THE TRACTOR
After every 50 hours of operation apply Cub Cadet 251HEP grease (or equivalent) to all lube fittings.
Wipe away all old grease and dirt from the lube fittings to prevent foreign materials from entering as the new grease is applied. Use a pressure lubricating gun to force new grease through the lube fittings of the following tractor components:
•Front axle pivot brackets (front and back). See Figure 69.
