Changing the Engine Coolant
POTENTIAL HAZARD
Coolant is hot and pressurized.
WHAT CAN HAPPEN
Discharge of hot pressurized coolant can
cause severe burns.
HOW TO AVOID THE HAZARD
Do not remove the radiator cap when the
engine is hot. Always allow the engine to
cool at least 15 minutes or until the
radiator cap is cool enough to touch
without burning your hand before
removing the radiator cap.
1. Park the machine on a level surface, lower the
loader arms, and turn the ignition key to "OFF"
to stop the engine. Remove the key.
2. Allow the engine and radiator to cool, then
remove the radiator cap (Fig. 12).

Note: If you wish, you can attach a 3/8 ID
hose to each of the two drain valves.
3. Open both coolant drain valves at the bottom of
the radiator and allow coolant to flow into a
drain pan. When coolant stops flowing, close
the drain valves.
4. Slowly fill the radiator with a 50/50 mixture of
water and permanent ethylene glycol anti–freeze.
Fill the radiator completely,.8 gal. (3.1 l) Install
the radiator cap.
5. Slowly fill the radiator until the level reaches the
upper line. DO NOT OVERFILL. Install the
radiator cap.
6. Start the engine and operate it until it is warm.
Recheck the coolant level in the reserve tank
after the engine has cooled down and replenish,
if required; refer to Check the Cooling System,
page 12.
