5. Separate the front of the snorkel
housing from the rear; then remove
the snorkel housing.
6. Remove two reinstallable rivets and
remove the splash guard. The radiator
cap can now be accessed in front of
the snorkels.
7. Carefully rotate the radiator cap
counterclockwise to release pressure;
then remove the cap.
8. Add coolant as necessary; then install
the radiator cap and access panel or
snorkel housing.

NOTE: Use a good quality, biode-
gradable glycol-based, automotive-
type antifreeze.
! 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
MP007A
coolant level. Add coolant as necessary.
Maintenance (Mud Pro)
When operating in muddy conditions, it is
extremely important to clean the radiator
core frequently. Arctic Cat requires
inspecting and/or flushing the radiator
core before each use to prevent overheat-
ing resulting in severe engine damage.
After cleaning, shine a light through the
radiator core while observing from the
opposite side to determine if all dirt and
debris have been removed.

NOTE: It is necessary to remove
MP003
four machine screws securing the
protective screen to the front of the
radiator and move it forward to prop-
erly flush the radiator core. Make
sure to secure the screen to the radi-
ator after cleaning.
CAUTION
Failure to remove dirt and debris
from the radiator prior to operating
the ATV may cause overheating
resulting in severe engine damage.
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
CF142A
nozzle at normal tap pressure.
