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 is approxi-
mately 1.4 L (1.5 U.S. qt). The cooling
system should be inspected daily for
leakage and damage. If leakage or dam-
age is detected, take the ATV to an autho-
rized Arctic Cat ATV dealer for service.
Also, the coolant level should be checked
periodically.
NOTE: High engine RPM, low
vehicle speed, or heavy load can
raise engine temperature. Decreas-
ing engine RPM, reducing load, and
selecting an appropriate transmis-
sion gear can lower the tempera-
ture.
The engine coolant will expand in the
radiator as the temperature increases.
Excessive coolant will flow to the cool-
ant overflow tank; then as the system
cools, coolant will be drawn back into the
radiator. The coolant level in the over-
flow tank should be maintained between
low and full marks on the tank.

When filling the cooling system, use a
coolant/water mixture which will satisfy
the coldest anticipated weather condi-
tions of the area in accordance with the
coolant manufacturer’s recommenda-
tions. While the cooling system is being
filled, air pockets may develop; there-
fore, run the engine for five minutes after
the initial fill, shut the engine off, and
then fill the cooling system.
NOTE: Use a good quality, biode-
gradable glycol-based, automotive-
type antifreeze.
Shock Absorbers
Each shock absorber should be visibly
checked weekly for excessive fluid leak-
age (some seal leakage may be observed
but it does not indicate the shock is in
need of replacement), cracks or breaks in
the lower case, or a bent shock rod. If any
one of these conditions is detected,
replacement is necessary.
NOTE: When the ATV is operated
in extremely cold weather (-23°C/
-10°F or colder), a small amount of
leakage may be present. Unless the
leakage is excessive, replacement
is not necessary.
CAUTION
Arctic Cat does not recommend
using 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
pressure.
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
necessary.
