MAINTENANCE
Cooling System
The engine coolant level is controlled or maintained by the recovery system. The recovery
system components are the overflow bottle, radiator filler neck, radiator pressure cap and
connecting hose.
As coolant operating temperature increases, the expanding (heated) excess coolant is forced
out of the radiator, past the pressure cap, and into the overflow bottle. As engine coolant
temperature decreases, the contracting (cooled) coolant is drawn back up from the tank, past
the pressure cap, and into the radiator.
Some coolant level drop on new vehicles is normal as the system is purging itself of trapped
air. Observe coolant levels and maintain as recommended by adding coolant to the overflow
bottle.
Adding or Changing Coolant
To ensure that the coolant maintains its ability to protect the engine, we recommend that the
system be completely drained every two years and a fresh mixture of antifreeze and water
added.
NOTICE: Do not mix different types of coolant in the cooling system when adding coolant. Mixing
types can result in damage to the cooling system.
POLARIS recommends the use of POLARIS Antifreeze 60/40 Premix or a 50/50 mixture of
high quality aluminum compatible anti-freeze/coolant and distilled water. POLARIS
antifreeze 60/40 is already premixed and ready to use. Do not dilute with water.
Always follow the manufacturer's mixing recommendations for the freeze protection
required in your area.
Any time the cooling system has been drained for maintenance or repair, replace the coolant.
If the recovery bottle has run dry, the level in the radiator should be inspected. Add coolant
as needed.
Radiator and Cooling Fan
Always check and clean the screen and radiator fins at the intervals outlined in the Periodic
Maintenance Chart beginning on page 73. Do not obstruct or deflect air flow through the
radiator by installing unauthorized accessories in front of the radiator or behind the cooling
fan. Interference with the radiator air flow can lead to overheating and consequent engine
damage.
NOTICE: Washing the vehicle with a high-pressure hose could damage the radiator fins and impair
the radiator's effectiveness. Using a high-pressure system is not recommended.
