Cooling System - Yamaha VENTURE PZ5NXJ Owner's Manual

Periodic maintenance and adjustment
21. Install the right side cover (PZ5NX), or in-
stall the right side cover and the right up-
per cover, and then close the shroud
(PZ5NT). NOTICE: If oil is leaking or the
oil level warning indicator comes on
when the engine is running, immedi-
ately turn the engine off and have a
Yamaha dealer check the snowmo-
bile. Continuing 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.
EWS00381
WARNING
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
allows any residual pressure to escape.
When the hissing sound has stopped,
press down on the cap while turning coun-
terclockwise and remove it.

Place the snowmobile on a level surface
and apply the parking brake.
Remove the top cover (PZ5NX) or open
the shroud (PZ5NT), and then remove
the right upper cover. (See page 44 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, other-
wise the cooling system will not be
protected against frost and corrosion.
If water has been added to the cool-
ant, have a Yamaha dealer check the
antifreeze content of the coolant as
soon as possible, otherwise the effec-
tiveness of the coolant will be re-
duced.
