Engine Coolant Inspection / Change Procedure - Polaris msx 110 Service Manual

Engine Coolant Level
The engine, oil cooler, and turbine bearing housing are cooled by an internal cooling system. A 50 / 50 mixture
of propolyne glycol (environmentally safe coolant) and distilled water must be used in warm--weather states. A
60 / 40 mixture of propolyne glycol and distilled water can be used in cold--weather states and where the tempera-
ture can drop below freezing.
The internal cooling system is a self--bleeding design. The lowest point in the circuit is located just below the water
pump housing.
1. The coolant level must be maintained between the
MIN and MAX marks on the side of the coolant
expansion tank. (Never overfill the expansion tank.)

Engine Coolant Change Procedure
1. Remove the hose that connects the coolant expansion
tank the water pump cover. The engine coolant will
drain into the engine compartment bilge.
2. Re--attach the hose. Open the two hull bilge plugs.
Place two containers directly under the bilge plugs.
3. Carefully lift the front of the boat to about 15 degrees
up. Allow all of the coolant to exit the engine
compartment.
4. Flush the bilge with clean water, and secure bilge
plugs.
5. Obtain new engine coolant, and slowly fill the
expansion tank to the MAX mark. Allow the system to
purge the air out of the circuits. (Level will go down
over short period of time.)
6. Repeat process two to three times. Never fill level
above MAX mark.
NOTE: The coolant level will drop after the first several operation cycles.
