Liquid Cooling System
NOTE: Debris in front of the engine or packed
between the cooling 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 can be found in Section 1.
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. Remove the four screws securing the radiator access
panel.

2. Move the panel forward until free of the ATV.
NOTE: Steps 3-5 are for Mud Pro models; for other
models, proceed to step 6.
3. Remove four cap screws securing the snorkel hous-
ing to the front inspection panel; then remove two
cap screws from the rear of the snorkel housing.

4. Separate the front of the snorkel housing from the
rear; then remove the snorkel housing.
MP003
5. Remove two reinstallable rivets and remove the
splash guard. The radiator cap can now be accessed
in front of the snorkels.
6. Carefully rotate the radiator cap counterclockwise to
release pressure; then remove the cap.
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 dam-
aged. Use only a garden hose with spray nozzle at nor-
mal tap pressure.
CAUTION
Continued operation of the ATV with high engine tem-
perature may result in engine damage or premature
wear.
