FOR ARCTIC CAT ATV DISCOUNT PARTS CALL 606-678-9623 OR 606-561-4983
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 pressure.
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.
CAUTION
Continued operation of the ATV with high engine temper-
ature may result in engine damage or premature wear.
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.
