Cooling System Safety

CAUTION
Discharge of hot, pressurized coolant or
touching a hot radiator and surrounding parts
can cause severe burns.
• 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.
• Do not touch the radiator and surrounding
parts that are hot.
DANGER
Swallowing engine coolant can cause
poisoning.
• Do not swallow engine coolant.
• Keep out of reach from children and pets.
Checking the Cooling
System
Service Interval: Before each use or daily
Check the coolant level at the beginning of each day.
The capacity of the system is 8.5 L (9 US qt).
1. Carefully remove the radiator cap and
expansion-tank cap
2. Check the coolant level in the radiator.
Note:
The radiator should be filled to the top
of the filler neck and the expansion tank filled
to the Full mark.
(Figure 88).
1. Expansion tank
3. If the coolant is low, add a 50/50 mixture of water
and ethylene glycol anti-freeze.
Important:
Do not use water only or
alcohol/methanol base coolants, as this may
cause damage.
4. Install the radiator cap and expansion-tank cap.
Servicing the
Engine-Cooling System
Service Interval: Every 100 hours
Every 2 years
This machine is equipped with a hydraulically driven
fan-drive system that automatically (or manually)
reverses to reduce the radiator/oil cooler and screen
debris buildup. While this feature can help reduce
the time required to clean radiator/oil cooler, it does
not eliminate the need for routine cleaning. Periodic
cleaning and inspection of the radiator/oil cooler is
still required.
1. Shut off the engine and raise the hood.
2. Clean the engine area thoroughly of all debris.
3. Clean both sides of the radiator/oil cooler area
thoroughly with compressed air
Note:
Start from the fan side and blow the
debris out toward the back. Then, clean from
the back side and blow toward the front. Repeat
this procedure several times until all chaff and
debris is removed.
Important:
Cleaning the radiator/oil cooler
with water can promote premature corrosion
and damage to components.
