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.
