ESU12043
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 (PZ50 / PZ50RT /
PZ50GT / PZ50MT) or open the shroud
(PZ50VT), and then remove the right up-
per cover. (See page 49 for removal pro-
cedures.)
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 soft water until it reaches the
“COLD LEVEL” mark. (See the following
section “Replenishing the coolant” for
more details.)
NOTICE:
Hard water or
salt water is harmful to the engine
parts. You may use boiled or distilled
water, if soft water is not available.
Tap water can be used temporarily in
an emergency.
[ECS00491]
4.
Install the right upper cover, and then in-
stall the top cover (PZ50 / PZ50RT /
PZ50GT / PZ50MT) or close the shroud
(PZ50VT).
Bleeding the cooling system
The cooling system must be bled if the cool-
ant reservoir becomes empty, if air can be
seen in the cooling system, or if there is a
cooling system leak. Consult a Yamaha deal-
er.
NOTICE
ECS00500
Operating the engine with an improperly
bled cooling system can cause overheat-
ing and severe engine damage.
Replenishing the coolant
1.
Remove the top cover (PZ50 / PZ50RT /
PZ50GT / PZ50MT) or open the shroud
(PZ50VT), and then remove the right up-
per cover. (See page 49 for removal pro-
cedures.)
2.
Remove the coolant reservoir cap, add
the recommended coolant until it reaches
the “COLD LEVEL” mark, and then install
the cap.
