If the engine has been running, the pressurized, hot
coolant can escape and 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 radiator and surrounding parts
that are hot.
• Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.

Service Interval: Before each use or daily
Clean any debris off of the screen, oil cooler, and front of the
radiator daily and more frequently when operating conditions

The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol antifreeze. Check the level
of coolant in the expansion tank at the beginning of each
day before starting the engine.
The coolant level should be up to upper line mark on the
expansion tank (Figure 36).

If the coolant level is low, complete the following procedure:
1. Remove the coolant expansion tank fill cap (Figure 36).
2. Add coolant into the expansion tank until it reaches the
upper mark on the expansion tank.
3. Install the expansion tank cap.
Changing the Engine Coolant
Have an Authorized Service Dealer change the engine coolant
yearly.
