Cooling System - Arctic Cat 2008 300 DVX Owner's Manual

MAINTENANCE IN DETAIL

COOLING SYSTEM

n
NOTE:
Debris in front of the engine or packed between the cooling fi ns of
the radiator can reduce cooling capability. Using a hose, pressure-
wash the radiator to remove any debris preventing air fl ow.
The cooling system capacity is approximately 1.4 L (1.5 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 coolant level should be checked
periodically.
Continued operation of the ATV with high engine temperature may
result in engine damage or premature wear.
n
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.
The engine coolant will expand in the radiator as the temperature
increases. Excessive coolant will fl ow to the coolant overfl ow tank;
then as the system cools, coolant will be drawn back into the radiator.
The coolant level in the overfl ow tank should be maintained between
low and high marks on the tank.
When fi lling the cooling system, use a coolant/water mixture which
will satisfy the coldest anticipated weather conditions of the area in
accordance with the coolant manufacturer's recommendations. While
the cooling system is being fi lled, air pockets may develop; therefore,
run the engine for fi ve minutes after the initial fi ll, shut the engine off,
and then fi ll the cooling system.
n
Note:
Use a good quality, biodegradable glycol-based, automotive-type
antifreeze.
Never check the coolant level when the engine is hot or the cooling
system is under pressure.
