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.
On the Utility, the cooling system capac-
ity is approximately 1.4 L (1.5 U.S. qt);
on the DVX, the cooling system capac-
ity is approximately 0.776 L (0.81 U.S.
qt). 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 cool-
ant level should be checked periodically.
NOTE: High engine RPM, low vehi-
cle speed, or heavy load can raise
engine temperature. Decreasing
engine RPM, reducing load, and
selecting an appropriate transmis-
sion gear can lower the temperature.
The engine coolant will expand in the
radiator as the temperature increases.
Excessive coolant will flow to the cool-
ant overflow tank; then as the system
cools, coolant will be drawn back into
the radiator. The coolant level in the
overflow tank should be maintained
between low and full marks on the tank.
KM136
When filling the cooling system, use a
coolant/water mixture which will sat-
isfy the coldest anticipated weather
conditions of the area in accordance
with the coolant manufacturer’s recom-
mendations. While the cooling system
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.
NOTE: Use a good quality, biode-
gradable glycol-based, automo-
tive-type antifreeze.
SHOCK ABSORBERS
Each shock absorber should be visibly
checked weekly for excessive fluid
leakage (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 con-
ditions is detected, replacement is nec-
essary.
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 nozzle at normal
tap pressure.
CAUTION
Continued operation of the ATV with
high engine temperature may result
in engine damage or premature wear.
! 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 ini-
tial 5-10 minutes, stop the engine,
allow the engine to cool down, and
check the coolant level. Add coolant
as necessary.
