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.
•
Do not operate the machine without the covers
in place.
•
Keep your fingers, hands, and clothing clear of
rotating fan and drive belt.
•
Shut off the engine and remove the key before
performing maintenance.

Checking the Cooling
System and Coolant Level
Service Interval: Before each use or daily Check
the level of the coolant level before
first starting the engine and daily
thereafter.
WARNING
If the engine has been running, the radiator
pressurizes and the coolant inside is 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. Check the level of the coolant in the expansion
tank (Figure 68).
Note:
The coolant level should be between the
marks on the side of the tank.
1. Expansion tank
2. If the coolant is low, add the recommended
replacement coolant as required. Do not use
water only or alcohol-based coolants. Do not
overfill.
3. Install the expansion-tank cap.
