MAINTENANCE
Cooling System
Operation
The engine coolant level is controlled or maintained by the recovery
system. The recovery system components are the overflow bottle, radia-
tor 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.
Tip: 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.
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 is already premixed
and ready to use. Do not dilute with water. See page 136 for the part
numbers of POLARIS products.
Tip: 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.
