Liquid Cooling System
NOTE: Debris in front of the
engine or packed between the cool-
ing fins of the radiator can reduce
cooling capability. Using a garden
hose, wash the radiator to remove
any debris preventing air flow.
The cooling system capacity can be
found in the specifications chart. The
cooling system should be inspected daily
for leakage and damage. If leakage or
damage is detected, take the vehicle to an
authorized dealer for service. Also, the
coolant level should be checked periodi-
cally.
NOTE: High engine RPM, low vehi-
cle speed, or heavy load can raise
engine temperature. Decreasing
engine RPM, reducing load, and
selecting an appropriate transmis-
sion gear can lower the temperature.
When filling the cooling system, use a
60/40 coolant/water mixture or one
which will satisfy the coldest anticipated
weather conditions of the area in accor-
dance with the coolant manufacturer’s
recommendations. While the cooling sys-
tem is being filled, air pockets may
develop; therefore, run the engine for
five minutes after the initial fill, shut the
engine off, and then fill the cooling sys-
tem to the bottom of the stand pipe in the
radiator neck.
Checking/Filling
1. Remove the rubber access plug from
the front fender.

2. Carefully rotate the radiator cap
counterclockwise to release pressure;
then remove the cap.

3. Add coolant as necessary; then install
the radiator cap and access plug.
NOTE: Use a good quality, biode-
gradable glycol-based, automotive-
type antifreeze.
Maintenance
When operating in muddy conditions, it is
extremely important to clean the radiator
core frequently. The manufacturer
requires inspecting and/or flushing the
radiator core before each use to prevent
overheating resulting in severe engine
damage. After cleaning, shine a light
through the radiator core while observing
from the opposite side to determine if all
dirt and debris have been removed.
CAUTION
Do not use a pressure washer to
clean the radiator core. The pressure
may bend or flatten the fins causing
restricted air flow, and electrical
components on the radiator could be
damaged. Use only a garden hose
with spray nozzle at normal tap pres-
sure.
CAUTION
Continued operation of the ATV with
high engine temperature may result
in engine damage or premature wear.
! WARNING
Never check the coolant level when
the engine is hot or the cooling sys-
tem is under pressure.
CAUTION
After operating the ATV for the initial
5-10 minutes, stop the engine, allow
the engine to cool down, and check
the coolant level. Add coolant as nec-
essary.
