Liquid Cooling System
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 ser-
vice. Also, the coolant level should be
checked periodically.
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 to the bottom
of the stand pipe in the radiator neck.
NOTE: Use a good quality, biode-
gradable glycol-based, automo-
tive-type antifreeze.
NOTE: High engine RPM, low
vehicle speed, or heavy load can
raise engine temperature.
Decreasing engine RPM, reducing
load, and selecting an appropriate
transmission gear can lower the
temperature.
To check/add coolant, use the following
procedure.
1. Remove the two reinstallable rivets
from the front of the radiator access
panel.

2. Lift the front of the access panel;
then slide the panel forward to dis-
engage the two rear tabs.

3. Move the panel rearward until free
of the rack.
4. Carefully rotate the radiator cap
counterclockwise to release pres-
sure; then remove the cap.

5. Add coolant as necessary; then
install the radiator cap and access
panel.
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.
! WARNING
Never check the coolant level when
the engine is hot or the cooling sys-
tem is under pressure.
