Fuel System; Coolant Level; Spark Plugs - Arctic Cat 2010 Crossfire 600 Operator's Manual

The snowmobile should be taken to an
authorized Arctic Cat Snowmobile
dealer at the end of each snowmobiling
season for general inspection and for
off-season storage servicing. This
inspection and servicing is at the
expense of the snowmobile owner.

FUEL SYSTEM

! WARNING
Whenever any maintenance or
inspection is made on the fuel sys-
tem in which there may be fuel
leakage, there should be no weld-
ing, smoking, open flames, etc., in
the area.
Gasoline Additives
Fuel de-icer can be used for all models.
Also, periodic use of an injector
cleaner is recommended especially in
the last tank of gasoline before storage.
Arctic Cat Fuel Stabilizer (p/n 0436-
907) should also be added to the last
tank of gasoline before storage.
Fuel Pickup Valves
All models are equipped with fuel
pickup valves in the gas tank. If ever
there is a restricted fuel flow and a
pickup valve is suspected, take the
snowmobile to an authorized Arctic
Cat Snowmobile dealer for this service.
If not under warranty, this service is at
the discretion and expense of the snow-
mobile owner.

COOLANT LEVEL

 NOTE: Use a good quality, ethyl-
ene glycol-based, automotive-type
coolant.
 NOTE: Always check the coolant
level with the engine cold.
Locate the appropriate FULL mark on
the coolant reservoir. If coolant is
below the FULL mark, add coolant to
the FULL mark.
MAINTENANCE

SPARK PLUGS

 NOTE: Always use the recom-
mended spark plugs in the engine.
See the appropriate specifications
chart for correct spark plug gap.
Varying terrain conditions and operat-
ing usage may require spark plugs of a
different heat range. For example, sus-
tained cross-country riding will usually
require colder heat-range spark plugs
while trail riding or other continual
slow speed operation will usually
require hotter heat-range spark plugs.
Removing/Installing
Spark Plugs
1. Remove the springs securing the
expansion chamber to the exhaust
manifold and resonator; then move
the expansion chamber out of the
way to access the spark plugs.
2. Remove the spark plug caps from
the plugs.
3. Using a spark plug wrench,
remove the plugs.
4. Install the plugs and finger-tighten.
5. Tighten the spark plugs to 19 ft-lb;
then install the spark plug caps.
6. Place the expansion chamber into
position and secure to the exhaust
manifold and resonator with the
springs.
Checking Spark Plugs
To see if the spark plugs being used are
of the proper heat range (after the
snowmobile has been operated under
normal driving conditions), remove the
spark plugs and examine the condition
of the center electrode insulator of each
spark plug.
