Cooling System Flushing - Polaris 2003 Genesis i Owner's Safety And Maintenance Manual

MAINTENANCE AND LUBRICATION

Cooling System Flushing

The watercraft uses water for propulsion and for cooling. Flushing the
cooling system with fresh water (never anti-freeze) will neutralize the
corroding effects of salt water or water with impurities like silt, sand,
alkali and other particulates. Flushing will also clean out other residue
left in the water passages of the watercraft cooling system. Flush the
water passages every day the watercraft is used, any time the craft has
been beached and before storing the craft for an extended time.
Failure to follow the recommended flushing procedure or flushing
the engine while it's hot could result in serious engine damage.
Always follow the recommended flushing procedures. Always
allow the engine to cool sufficiently before flushing. Always flush
the cooling system any time the watercraft has been beached.
Polaris recommends the use of Flush Kit PN 2871443 (carb models) or
Flush Kit PN 2873623 (DI models) when flushing the cooling system.
1. Attach a garden hose to the female coupler/hose attachment.
2. Snap the male and female coupler together.
3. Start the watercraft engine and immediately turn on the water
faucet.
4. Rev the engine intermittently for one minute to completely flush
the cooling system.
5. Turn off the water faucet.
6. When all water has exited the cooling system, turn off the engine.
NOTE: This step should not take longer than 10 seconds.
7. Press the button on the female coupler/hose attachment and
separate from male coupler.
