Coolant Level Inspection
With the engine at operating temperature, the coolant level
should be between the upper and lower marks on the re-
covery bottle. If not:
1. Remove recovery bottle cap. Inner splash cap vent
hole must be clear and open.
2. Fill recovery bottle to upper mark with Polaris
Premium 60/40 Anti Freeze / Coolant or 50/50 or
60/40 mixture of antifreeze and distilled water.
3. Reinstall cap.
NOTE: If coolant is excessively low in the radiator, coolant
will not circulate or be drawn in from the recovery bottle.
Coolant Strength
Test the strength of the coolant using an antifreeze
hydrometer. A 50/50 or 60/40 mixture of antifreeze and
distilled water will provide the optimum cooling, corrosion
protection, and antifreeze protection. Do not use tap wa-
ter, straight antifreeze, or straight water in the system. Tap
water contains minerals and impurities which build up in
the system. Straight water or antifreeze will cause the sys-
tem to freeze.
Cooling System Hoses
1. Inspect all hoses for cracks, deterioration, abrasion or
leaks. Replace if necessary.
2. Check tightness of all hose clamps.
Radiator
1. Check radiator air passages for restrictions or
damage.
2. Carefully straighten any bent radiator fins.
3. Remove any obstructions with compressed air or low
pressure water.
Cooling System Pressure Test
Refer to page 3.6 for pressure test procedure.
