Oil Level Check
NOTE: Read the entire oil check procedure before checking the oil
level.
The oil level will rise as engine temperature increases. The oil level
will be lower when the engine is cold. To obtain a proper oil level
reading, the snowmobile must be on a level surface, and the engine
coolant temperature must be between 145 and 160 degrees F. (63-71
degrees C). Never add or remove oil if the engine coolant temperature
is not within the specified range.
NOTE: Always check the oil level before operating a snowmobile
that has tipped over.
CAUTION
Severe engine damage may occur if procedures for checking the
oil level are not followed precisely. Always check the oil with the
snowmobile positioned on a level surface. Always check the oil
when the coolant temperature is within the specified range.
1. Position the vehicle on a level surface.
2. If the engine is cold, start the engine and allow it to idle until the
engine coolant temperature reaches the specified range. Proceed to
step 4.
3. If the engine has been running, stop the engine and verify that
coolant temperature is within the specified range for performing
the oil check. Allow the engine to cool if necessary. When the
coolant is within the specified range, restart the engine and allow it
to idle for no more than 20 seconds to circulate the oil back into
the tank.
4. Turn the engine off.
NOTE: Check the oil level within
three minutes, before the
coolant temperature (and
oil level) begin to drop.
5. Remove the dipstick (L)
from the oil tank.
