Shock Absorbers - Arctic Cat 650 2011 Operator's Manual

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.
7. 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
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
four machine screws securing the
protective screen to the front of the
radiator and move it forward to
properly flush the radiator core.
Make sure to secure the screen to
the radiator 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
CF142A
air flow, and electrical components
on the radiator could be damaged.
Use only a garden hose with spray
nozzle at normal tap pressure.

Shock Absorbers

Each shock absorber should be visibly
checked weekly for excessive fluid leak-
age (some seal leakage may be observed
but it does not indicate the shock is in
need of replacement), cracks or breaks in
the lower case, or a bent shock rod. If any
one of these conditions is detected,
replacement is necessary.

NOTE: When the ATV is operated in
extremely cold weather (-23°C/-10°F or
colder), a small amount of leakage may
be present. Unless the leakage is
excessive, replacement is not neces-
sary.
The shock absorber has a spring force
adjustment sleeve with five adjustment
positions to allow the spring to be adjusted
for different riding and loading conditions.
If the spring action is too soft or too stiff,
adjust it according to the chart.
