Liquid Cooling System
NOTE: Debris in front of the engine or packed between
the cooling fins of the radiator can reduce cooling capa-
bility. Using a garden hose, wash the radiator to remove
any debris preventing air flow.
The cooling system capacity can be found in the specifi-
cations chart. The cooling system should be inspected
daily for leakage and damage. If leakage or damage is
detected, take the ATV to an authorized 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. Decreasing
engine RPM, reducing load, and selecting an appro-
priate transmission 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 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 system to the bot-
tom of the stand pipe in the radiator neck.
Checking/Filling
1. Locate the coolant reservoir on the right side behind
the radiator.

2. Remove the cap and fill with the appropriate coolant
until coolant level is between the LOW and FULL
lines. Do not overfill.
3. Install the cap on the reservoir.
Muffler/Spark Arrester
At the intervals shown in the Periodic Maintenance
Chart, clean the spark arrester using the following proce-
dure.
1. Remove the cap screws securing the spark arrester
assembly to the muffler; then loosen and remove the
arrester.

2. Using a suitable brush, clean the carbon deposits
from the screen taking care not to damage the screen.
NOTE: If the screen or gasket is damaged in any
way, it must be replaced.
3. Install the spark arrester assembly with gasket; then
secure with the cap screws. Tighten to 48 in.-lb.

Adjusting Throttle Cable
To adjust the throttle cable free-play, follow this procedure.
1. Slide the rubber boot away; then loosen the jam nut
from the throttle cable adjuster.
CAUTION
Arctic Cat does not recommend using a pressure washer
to clean the radiator core. The pressure may bend or flat-
ten the fins causing restricted air flow, and electrical com-
ponents 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 temper-
ature may result in engine damage or premature wear.
! WARNING
Wait until the muffler cools to avoid burns.
