NOTE: The cooling system is a closed type. Normally,
to prevent air from entering the system, the radiator cap
should not be removed.

If the overflow reservoir is empty, the radiator cap
should be removed and the coolant level in the radiator
checked before adding coolant to the reservoir. If neces-
sary, first refill the system through the radiator filler neck
as follows:

WARNING: It is dangerous to remove the
radiator cap when the system is hot. Allow

the system to cool before removing the
radiator cap.

1. Turn the radiator cap counterclockwise to the first

stop to release any pressure.

2. Push downward on the cap and turn counter-clock-

wise until the cap stops then lift cap off.

3. Slowly pour coolant into the filler neck until the level

reaches the bottom of the filler neck overflow flange.

4. Wait a few minutes to allow as much air as possible

to escape through the filler neck, then reinstall the
radiator cap.

5. Fill the overflow reservoir to the “FULL” mark.
6. Start the engine and allow it to run for a short period.

Stop the engine.

7. Recheck the coolant level in the overflow reservoir

and refill as needed. Reinstall the reservoir cap.

5. Check O-ring on drain plug and replace if missing or

in poor condition.

6. Install and tighten drain plug.

IMPORTANT:

Dirt and debris in oil may cause damage

to transfer case. Clean area around opening before
removing oil cap.

7. Remove oil cap and add

approximately 64 oz of

80W-90 Shell Dentax Low Foam Oil

NOTE

: If necessary, you may remove the fill level plug to

assist with determining the level to which the transmis-
sion may be filled. See Figure 9. When oil begins coming
out of fill level opening, the transmission is full. Replace
fill level plug when finished.

8. Install oil cap, and lower and latch cargo box.

Checking Engine Coolant Level

Before each use, the engine coolant level in the overflow
reservoir should be checked to ensure it is within the
operating range. Engine coolant absorbs heat from the
engine and transfers the heat to the air flowing through
the radiator. If the coolant level becomes low, the engine
may overheat and could cause severe damage to the
engine.
Use a permanent type antifreeze containing corrosion
and rust inhibitors. Dilute the antifreeze with water at a 1
: 1 ratio to mix the coolant solution (50% antifreeze : 50%
water).

NOTE

: Distilled water is recommended for the coolant

solution IF your tap water has a high mineral content.
Minerals cause scaling in the engine and the radiator
coolant passages. System efficiency will be greatly
reduced over time and severe engine damage may result.
Refer to the antifreeze manufacturer’s instructions for
additional information on dilution procedures.

1. Check the coolant level when the engine is cold and

the utility vehicle is on a level surface.

2. Raise the hood and check the coolant level in the

overflow reservoir on the right side of the engine.

3. If the coolant level is below the “LOW” mark, remove

the cap from the reservoir and add coolant solution to
the “FULL” mark. Refer to Figure 10.
