
NOTE: A disabled ECT system WILL NOT cause
engine damage; however, a failed ECT system will
have slower throttle response and may produce
slightly less top-end performance.
Testing Exhaust Temperature
Sensor
1. Disconnect the sensor harness; then remove the
sensor from the exhaust pipe.
2. Suspend the sensor (only up to the threads) in a
container filled with automatic transmission oil;
then slowly heat the oil on a hot plate.
3. Using a fluid thermometer, closely monitor the oil
temperature, and using a digital multimeter with
the leads connected to the sensor leads, observe
the resistance reading.
4. The resistance must be within the temperature
range (see chart).
5. If the resistance and temperature are not within
specifications, replace the sensor.

NOTE: Before replacing the sensor, repeat the
test to confirm results.
Handlebar Tilt
The handlebar can be adjusted to the operator’s prefer-
ence. To adjust the handlebar, use the following proce-
dure:
1. Loosen the eight cap screws securing the handlebar
caps to the riser and the riser to the steering post.
SNO-2236
2. Adjust the handlebar up or down to operator’s
desired tilt, tighten the cap screws evenly to 15 ft-
lb, and check steering for maximum right/left turn-
ing capabilities.

NOTE: Do not adjust the handlebar to a position
that allows the brake fluid to be below the low
mark on either side of the master cylinder.
Rear Bumper
The rear bumper can be removed and replaced. To remove/
install a rear bumper, use the following procedure.
1. On the inside of the tunnel, drill out all rivets and
remove both screws and nuts securing the rear
bumper to both sides of the tunnel.
2. Remove the existing bumper and install the new
one aligning the holes with the holes in the brack-
ets; then rivet the rear bumper to both sides of the
tunnel. Secure the front of the bumper using the
existing machine screws and nuts.
Exhaust System
The exhaust system is designed to reduce noise and to
improve the total performance of the engine. If any
exhaust system component is removed from the engine
and the engine is run, severe engine damage will result.
Liquid Cooling System
The cooling system should be inspected daily for leak-
age and damage. Also, the coolant level should be
checked daily. If leakage or damage is detected and the
operator does not feel qualified to service the cooling
system, see an authorized Arctic Cat Snowmobile
dealer for this service.
When filling the cooling system, use a coolant/water
mixture which will satisfy the coldest anticipated
weather conditions of your area in accordance with the
coolant manufacturer’s recommendations. While the
cooling system is being filled, air pockets may
develop; therefore, fill the bottle and run the engine for
five to ten minutes after the initial fill (until the ther-
mostat opens); then add more coolant if necessary. Fill
the coolant tank and take the snowmobile for a test
ride. Let the engine cool down; then recheck the cool-
ant level and add if necessary.

NOTE: Use a good quality, glycol-based, automo-
tive-type antifreeze.

! WARNING
Tighten cap screws according to specifications to pre-
vent unexpected “fold-down” of the handlebar during
operation over rough terrain. DO NOT offset the han-
dlebar so steering capabilities are altered or throttle
and brake controls will be affected.
CAUTION
After operating the snowmobile for the initial 5-10 min-
utes, stop the engine, allow the engine to cool down,
and check the coolant level. Add coolant as neces-
sary.
