Section 09 COOLING SYSTEM
Subsection 01 (CIRCUIT, COMPONENTS AND CARE)
Refill cooling system as described below.
COOLANT REPLACEMENT
Recommended Coolant
Useablendof50%antifreezewith50%deminer-
alized water. Premixed antifreeze/water is avail-
able test (P/N 293 600 038).
NOTE: Using a blend of 40% antifreeze with 60%
demineralized water will improve the cooling effi-
ciency when watercraft is used in particularly hot
weather and/or hot water condition.
To prevent antifreeze deterioration, always use
the same brand. Never mix different brands
unless cooling system is completely flushed and
refilled.
Do not reinstall pressure cap.
CAUTION: To prevent rust formation or freez-
ing condition in cold areas, always replenish
the system with 50% antifreeze and 50% dem-
ineralized water. Pure antifreeze will freeze
at a higher temperature than the optimal wa-
ter/antifreeze mix. Always use ethylene glycol
antifreeze containing corrosion inhibitors
specifically recommended for aluminum en-
gines. Using water tap instead of demineral-
ized water, would contribute to make deposits
in cooling system and to reduce antifreeze effi-
ciency. This could lead to engine overheating.

Coolant Replacement Procedure
WARNING
To prevent burning yourself do not remove
the expansion tank cap or loosen the ride
plate drain plug if the engine is hot.
Completely drain the system and clean as de-
scribed above.
Watercraft should be level, engine cold and drain
plug removed for refilling.
Place a container under drain plug to collect an-
tifreeze.
Ask someone to pour antifreeze in expansion tank
while watching antifreeze and air bubble flowing
out through drain hole. When no air bubbles
escape, reinstall drain plug. Torque to 8.3 N•m
(73 lbf•in).
