NOTE: The access panels and
hood must be removed for this pro-
cedure.
1. Remove the filler cap from the cool-
ant reservoir.
2. Verify the coolant level is at the bot-
tom of the tab in the filler neck.
0746-117
3. If the coolant is below the tab, add
coolant to the reservoir until at the tab.
Spark Plugs
NOTE: Always use the recom-
mended spark plugs in the engine.
See the appropriate specifications
sheet for correct spark plug gap.
Varying terrain conditions and operating
usage may require spark plugs of a differ-
ent heat range. For example, sustained
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.
NOTE: Spark plug maintenance
may be done by the snowmobile
owner if qualified to do so. If the
owner does not feel qualified, take
the snowmobile to an authorized
Arctic Cat Snowmobile dealer for
this service. This service is at the
discretion and expense of the snow-
mobile owner.
NOTE: For this procedure, the
hood and side panels must be
removed.
1. On the 7000/9000, remove the spark
plug end caps; on the 5000, remove
the two cap screws securing the igni-
tion coils to the cylinder head cover.
2. Using a 3/8-in. drive ratchet,
adapter, and a 5/8-in. spark plug
socket, remove the spark plugs.
NOTE: Prior to installing the spark
plugs, check the gap between the
electrode and ground strap. The clear-
ance should be 0.9 mm (0.035 in.)
(5000/9000) or 0.7-0.8 mm (0.028-0.031
in.) (7000).
3. Install the spark plugs. Tighten to 96
in.-lb.
4. On the 5000, install the ignition
coils onto the cylinder head making
sure they are fully sealed. On the
7000/9000, install the spark plug
end caps.
CAUTION
If the coolant is below the neck and if
coolant has been added, immediately
inspect for leakage and/or damage. If
leakage or damage is detected, take
the snowmobile to an authorized Arc-
tic Cat Snowmobile dealer for ser-
vice. If not under warranty, this
service is at the discretion and
expense of the snowmobile owner.

CAUTION
If adjusting spark plug gap is neces-
sary, do not use the center electrode
as a leverage point. Damage to the
plug may occur.
