Liquid Cooling System - Arctic Cat 500 Operato's Manual

Liquid Cooling System


NOTE: Debris in front of the engine
or packed between the cooling fins of
the radiator can reduce cooling capa-
bility. Using a garden hose, wash the
radiator to remove any debris pre-
venting 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 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.
CAUTION
Continued operation of the ATV with
high engine temperature may result
in engine damage or premature wear.

NOTE: High engine RPM, low vehi-
cle speed, or heavy load can raise
engine temperature.
engine RPM, reducing load, and
selecting an appropriate transmis-
sion gear can lower the temperature.
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
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.
