Liquid Cooling System

NOTE: Debris in the engine com-
partment 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.
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.
The cooling system capacity can be found
in the specification charts. The cooling sys-
tem should be inspected daily for leakage
and damage. If leakage or damage is
detected, take the vehicle to an authorized
Arctic Cat dealer for service. Also, the cool-
ant level should be checked periodically.
CAUTION
Continued operation of the vehicle
with high engine temperature may
result in engine damage or premature
wear.
NOTE: High engine RPM, low vehi-
cle speed, or heavy load can raise
engine temperature.
engine RPM, reducing load, and
selecting an appropriate transmis-
sion gear can lower the temperature.
When filling the cooling system, use a
coolant/water mixture which will satisfy
the coldest anticipated weather conditions
of the area in accordance with the coolant
manufacturer's recommendations.
While the cooling system is being filled,
air pockets may develop; therefore,
remove the bleed plug on the coolant
pipe at the front of the engine allowing
trapped air to escape. When pure coolant
(no air) flows from the bleed hole, install
the bleed plug, tighten securely, and then
fill the cooling system to the bottom of
the stand pipe in the radiator neck. Run
the engine for five minutes after the ini-
tial fill; then shut off the engine and
recheck coolant level.

NOTE: Use a good quality, biode-
gradable glycol-based, automotive-
type antifreeze.
Never check the coolant level when
the engine is hot or the cooling sys-
tem is under pressure.
After operating the vehicle for the ini-
tial 5-10 minutes, stop the engine,
allow the engine to cool down, and
check the coolant level. Add coolant
as necessary.

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 vehicle is oper-
ated 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.
This vehicle is equipped with adjustable
shock absorbers in the front and rear to
Decreasing
allow for different driving and loading
conditions.
The front shock absorbers have an adjust-
ment sleeve with five preload adjustment
positions that can be turned with a special
spanner wrench to increase or decrease
coil spring tension. The rear shock
absorbers combine fixed pre-load springs
and a variable air assist to provide adjust-
ment allowing for differing driving and
loading conditions.
1. To adjust the spring force on the front
shock absorbers, rotate the pre-load
adjustment sleeve with a suitable
spanner wrench until desired spring
tension is achieved.
