Maintenance

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
Coolant specification: 50/50 mixture of water and ethylene
glycol antifreeze
Cooling system capacity: 8.5 L (9 US qt).
1. Carefully remove the radiator cap.
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.
