15. Start the engine, warm it up for several

cedure.)

●
When adding the engine oil, be careful
not to fill above the “H” level mark on the
dipstick.
●
Use only 4-stroke engine oil.
●
Make sure that no foreign material en-
ters the engine oil tank.
17. Start the engine, and then let it idle for
several minutes while checking it for oil
leakage. If oil is leaking, immediately turn
the engine off and make sure that the en-
gine oil drain bolt, oil tank drain bolt, cyl-
inder head cap, and the oil filler cap are
installed correctly.
18. Turn the engine off, and then connect the
oil level gauge coupler.
CAUTION:
ECS00470
If oil is leaking or the oil level warning indi-
cator comes on when the engine is run-
ning, immediately turn the engine off and
have a Yamaha dealer check the snowmo-
bile. Continuing to operate the engine un-
der such conditions could cause severe
engine damage.
19. Install the bottom panel, the right lower
cover, and the left lower cover.
20. Install the right side cover, the left side
cover, and the shroud.

Cooling system
The coolant level should be checked before
each ride. In addition, the cooling system
must be bled of air at the intervals specified in
the periodic maintenance and lubrication
chart.
WARNING
EWS00390
Do not remove the radiator cap when the
engine is hot. Scalding hot fluid and steam
may be blown out under pressure, which
could cause serious injury.
When the engine has cooled, place a thick
rag or towel over the radiator cap, and
slowly rotate the cap counterclockwise to
the detent. This procedure allows any re-
sidual pressure to escape. When the hiss-
ing sound has stopped, press down on the
cap while turning counterclockwise and
remove it.
