Coolant Strength / Type; Cooling Hoses; Radiator; Cooling System Pressure Test - Polaris 2007 SPORTSMAN X2 800 Service Manual

Coolant Strength / Type

Test the strength of the coolant using an antifreeze
hydrometer.
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 water, straight antifreeze, or
straight water in the system. Tap water contains
minerals and impurities which build up in the
system.
• Straight water or antifreeze may cause the system
to freeze, corrode, or overheat.

Cooling Hoses

Inspect all hoses for cracks, deterioration, abrasion or leaks.
Replace if necessary.
Upper Radiator Hose
Lower Radiator Hose
1. Check tightness of all hose clamps.
2. Do not over-tighten hose clamps at radiator or radiator
fitting may distort, causing a restriction or leak.

Fan

Radiator

1. Check radiator external air flow 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

See Chapter 3 for pressure test procedures.

Reservoir Level Inspection

WARNING
Never remove the radiator pressure cap when the
engine is warm or hot. Escaping steam and fluid
can cause severe burns. The engine must be
allowed to cool before removing the pressure cap.
Remove any obstructions with compressed air or low pressure
water.
With the engine at operating temperature, the coolant level
should be between the upper and lower marks on the coolant
reservoir. If it is not:
1. Remove reservoir cap. Verify the inner splash cap vent
hole is clear and open.
2. Fill reservoir to upper mark with Polaris Premium 60/40
Anti Freeze / Coolant (PN 2871323) or a mixture of
antifreeze and distilled water as required for freeze
protection in your area.
3. Reinstall cap.
NOTE: If overheating is evident, allow system to
cool completely and check coolant level in the
radiator. Inspect for signs of trapped air in system.
