Liquid Cooling System; Shock Absorbers - Arctic Cat XC 450 Operator's Manual

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.
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.
The cooling system capacity can be found in the specifications chart. The
cooling system should be inspected daily for leakage and damage. If leak-
age or damage is detected, take the ATV to an authorized Arctic Cat ATV
dealer for service. Also, the coolant level should be checked periodically.
CAUTION
Continued operation of the ATV with high engine temperature
may result in engine damage or premature wear.

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.
When filling the cooling system, use a coolant/water mixture which will
satisfy the coldest anticipated weather conditions of the area in accor-
dance with the coolant manufacturer's recommendations. While the cool-
ing 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 to the bottom of the stand pipe in the radiator neck.
Checking/Filling
1. Locate the coolant reservoir on
the right side behind the radiator.
2. Remove the cap and fill with the
appropriate coolant until coolant
level is between the LOW and
FULL lines. Do not overfill.
3. Install the cap on the reservoir.

Shock Absorbers

Each shock absorber should be visi-
bly 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 conditions is
detected, replacement is necessary.

NOTE: When the ATV is
operated in extremely cold
weather (-23°C/-10°F
colder), a small amount of
leakage may be present.
Unless leakage is excessive,
replacement is not necessary.
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.
