Clean the radiator hourly if conditions are extremely
dusty and dirty; refer to

The cooling system is filled with a 50/50 solution
of water and permanent ethylene glycol anti-freeze.
Check the coolant level at the beginning of each day
before starting the engine.
The capacity of the cooling system is approximately
5.7 L (6 US qt).
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 coolant level in the expansion tank
(Figure 57).
Note:
With a cold engine, the coolant level
should be approximately midway between the
marks on the side of the tank.
