Cooling System
Maintenance

Cooling System Safety

•
Swallowing engine coolant can cause
poisoning; keep out of reach from children and
pets.
•
Discharge of hot, pressurized coolant or touching
a hot radiator and surrounding parts can cause
severe burns.
– Always allow the engine to cool at least 15
minutes before removing the radiator cap.
– Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
Checking the Cooling
System
Service Interval: Before each use or daily—Check
the level of coolant in the expansion
tank and clean debris off the screen,
oil cooler, and front of the radiator.
The cooling system is filled with a 50/50 solution of
water and permanent ethylene glycol antifreeze. The
capacity of the cooling system is 9.5 L (10 US qt).
DANGER
The rotating fans and drive belts can cause
personal injury.
• Do not operate the machine without the
covers in place.
• Keep your hands and clothing clear of the
rotating fan and drive belt.
• Shut off the engine and remove the ignition
key before performing maintenance.
CAUTION
If the engine has been running, the
pressurized, hot coolant can escape and
cause burns.
• Do not open the radiator cap when the
engine is running.
• Use a rag when opening the radiator cap,
and open the cap slowly to allow steam to
escape.
1. Check the level of coolant in the expansion tank
(Figure 81).
