Cooling System
Maintenance
Servicing the Cooling System
Coolant specification: a mixture of 50% ethylene glycol
and 50% water
Note: An antifreeze having a mixture of 50% ethylene
glycol and 50% water will protect the engine to -37°C (-34°F)
throughout the year.
Engine and radiator coolant capacity: 18.5 L (19.5 US qt)
Important: Using over-concentrated or high-silicate
antifreeze can damage the engine.
WARNING
If you remove the recovery-tank cap from a hot
engine, hot coolant could spray, causing scalding.
• Wear face protection when opening the radiator
cap.
• Allow the cooling system to cool down to below
50°C (120°F) before removing the recovery-tank
cap.
• Follow the instructions for checking and
maintaining the engine cooling system.
WARNING
Coolant is toxic.
• Keep coolant away from children and pets.
• If you are not re-using the coolant, dispose of it
according to local environmental regulations.
Checking the Coolant Level
Service Interval: Every 50 hours
WARNING
If the engine has been running, the radiator will be
pressurized and the coolant inside will be hot. If
you remove the cap, coolant may spray out, causing
severe burns.
• Do not remove the recovery-tank cap to check
coolant levels.
• Do not remove the recovery-tank cap when the
engine is hot. Allow the engine to cool for at
least 15 minutes or until the radiator cap is cool
enough to touch without burning your hand.
1. Park the machine on a level surface, stop the engine,
and remove the ignition key.
2. Allow the engine to cool.
3. Remove the left side panel; refer to
Panels (page
44).
4. Check the coolant level by looking at the sight gauge in
the side of the surge tank
Note: You should see that the coolant level is above
the midpoint of the sight gauge.

5. If the coolant level is low, preform the following:
A. Remove the 2 hex-head bolts that secure the to
the hood of the machine, and open the reservoir
door
(Figure
B. Remove the recovery-tank cap from the recovery
tank, and add coolant until the level is up to the
midpoint of the sight gauge
Important: Do not overfill the surge tank
Note: If coolant level is low, check for leaks in
the hoses, radiator, and the recovery tank.
C. Install the recovery-tank cap, ensuring that it is
tightly sealed.
D. Close the reservoir door and secure it with the 2
hex-head bolts that you removed in step A.
6. If the air temperature is below 0°C (32°F), mix the
ethylene glycol and water completely by running the
engine at operating temperature for 5 minutes.
7. Install the left side panel; refer to
Panels (page
45).
