1. Leak indicator hole
INSPECTION
Check general condition of hoses and clamp tight-
ness.
Pressure Cap
Using a pressure cap tester, check pressure cap
efficiency. If the efficiency is feeble, install a new
90 kPa (13 PSI) cap (do not exceed this pressure).
COOLANT REPLACEMENT
WARNING
To avoid potential burns, do not remove the
expansion tank cap or loosen the ride plate
drain plug if the engine is hot.
Recommended Coolant
Use premixed antifreeze (P/N 219 700 362) or a
blend of 50% antifreeze with 50% demineralized
water.
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.
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 water/
antifreeze mix. Always use ethylene glycol an-
tifreeze containing corrosion inhibitors specif-
ically recommended for aluminum engines.
Using water tap instead of demineralized
water, would contribute to make deposits in
cooling system and to reduce antifreeze effi-
ciency. This could lead to engine overheating.
Draining the System
WARNING
Never drain or refill cooling system when en-
gine is hot.
Remove coolant expansion tank cap.
To drain cooling system, unscrew cooling system
drain plug at the rear of ride plate.
NOTE:
Raising the front of the vehicle will con-
tribute to drain the cooling system.

1. Cooling drain plug
Use an appropriate container to collect coolant.
Dispose coolant as per local regulations.
Do not reinstall drain plug at this time.
Cleaning the System
CAUTION:
Cleaning the cooling system as
per the following procedure is required when
engine overheats (assuming everything else
is operating normally) or each time coolant is
replaced.
