Engine Coolant

Recommended Engine Coolant
Always use ethylene-glycol antifreeze
containing corrosion inhibitors specif-
ically formulated for internal combus-
tion aluminum engines.
NOTE: When available, it is recom-
mended to use biodegradable an-
tifreeze compatible with internal com-
bustion aluminum engines. This will
contribute to protect the environment.
Fill cooling system with BRP PRE-
MIXED COOLANT (P/N 219 700 362),
or with a water and antifreeze solution
(50% distilled water, 50% antifreeze).
NOTE: Using a blend of 40% an-
tifreeze with 60% demineralized wa-
ter will improve the cooling efficiency
when watercraft is used in particularly
hot weather and/or hot water condi-
tion.
To prevent antifreeze deterioration, al-
ways use the same brand. Never mix
different brands unless cooling system
is completely flushed and refilled. Re-
fer to an authorized Sea-Doo dealer.

TYPICAL
1. Expansion tank cap
With watercraft on a level surface,
coolant level should be between MIN.
and MAX. marks on coolant reservoir
when engine is cold.
TYPICAL - COOLANT EXPANSION TANK
1. Level between marks when engine is cold
NOTE: The watercraft is level when
it is in water. When on a trailer, raise
trailer tow pole and block in this posi-
tion when bumper rail is level.
Add coolant/demineralized water to
adjust coolant level between marks
as required. Use a funnel to avoid
spillage. Do not overfill.
Properly reinstall and tighten filler cap,
then reinstall ventilation box and close
compo-
seat.
NOTE: A cooling system that fre-
quently requires coolant is an indica-
tion of leaks or engine problems. See
an authorized Sea-Doo dealer.
