Periodic maintenance and adjustment NOTICE: If oil is leaking or the oil level warning indicator comes on when the engine is running, immediately turn the engine off and have a Yamaha dealer check the snowmobile. Continuing to operate the engine under such conditions could cause severe engine damage. [ECS00471] ESU12047 To check the coolant level 1. 2. Place the snowmobile on a level surface and apply the parking brake. Remove the top cover (PZ50RT / PZ50GT / PZ50MT) or open the shroud (PZ50VT), and then remove the right upper cover. (See page 49 for the procedures.) Check the coolant level in the coolant reservoir when the engine is cold. If the coolant level is below the "COLD LEVEL" mark, add coolant until it reaches the "COLD LEVEL" mark. (See the following section "Replenishing the coolant" for more details.) NOTICE: If coolant is not available, use distilled water or soft tap water instead. Do not use hard water or salt water since it is harmful to the engine. If water has been used instead of coolant, replace it with coolant as soon as possible, otherwise the cooling system will not be protected against frost and corrosion. If water has been added to the coolant, have a Yamaha dealer check the antifreeze content of the coolant as soon as possible, otherwise the effectiveness of the coolant will be reduced. [ECS00492] Cooling system The coolant level should be checked before each ride. In addition, the cooling system must be bled at the intervals specified in the periodic maintenance and lubrication chart. EWS00380 3. WARNING Do not remove the coolant reservoir 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 coolant reservoir cap, and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual pressure to escape. When the hissing sound has stopped, press down on the cap while turning counterclockwise and remove it. 1 1. Coolant reservoir cap 1. "COLD LEVEL" mark 4.

NOTICE:
If oil is leaking or the oil level
warning indicator comes on when the
engine is running, immediately turn
the engine off and have a Yamaha
dealer check the snowmobile. Con-
tinuing to operate the engine under
such conditions could cause severe
engine damage.

Cooling system
The coolant level should be checked before
each ride. In addition, the cooling system
must be bled at the intervals specified in the
periodic maintenance and lubrication chart.
WARNING
EWS00380
Do not remove the coolant reservoir cap
when the engine is hot. Scalding hot fluid
and steam may be blown out under pres-
sure, which could cause serious injury.
When the engine has cooled, place a thick
rag or towel over the coolant reservoir
cap, and slowly rotate the cap counter-
clockwise to the detent. This procedure al-
lows any residual pressure to escape.
When the hissing sound has stopped,
press down on the cap while turning coun-
terclockwise and remove it.
To check the coolant level
1.
Place the snowmobile on a level surface
and apply the parking brake.
2.
Remove
the
top
cover
(PZ50RT /
PZ50GT / PZ50MT) or open the shroud
(PZ50VT), and then remove the right up-
per cover. (See page 49 for the proce-
dures.)
3.
Check the coolant level in the coolant
reservoir when the engine is cold. If the
coolant level is below the “COLD LEVEL”
mark, add coolant until it reaches the
“COLD LEVEL” mark. (See the following
section “Replenishing the coolant” for
more details.)
NOTICE:
If coolant is not
available, use distilled water or soft
tap water instead. Do not use hard wa-
ter or salt water since it is harmful to
the engine. If water has been used in-
stead of coolant, replace it with cool-
ant as soon as possible, otherwise the
cooling system will not be protected
against frost and corrosion. If water
has been added to the coolant, have a
Yamaha dealer check the antifreeze
content of the coolant as soon as pos-
sible, otherwise the effectiveness of
the coolant will be reduced.

4.
Install the right upper cover, and then in-
stall the top cover (PZ50RT / PZ50GT /
PZ50MT) or close the shroud (PZ50VT).
