MAINTENANCE AND LUBRICATION
Engine Cooling System
Oil Cooler (ATP 330)
The oil cooling system requires little maintenance other than to make
sure the cooler is kept free of mud and debris. Change the engine oil
as recommended in the maintenance schedule.
Cooling System Operation (ATP 500)
The engine coolant level is controlled or maintained by the recovery
system. The recovery system components are the recovery 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 recovery 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.
NOTE:
Some coolant level drop on new machines is normal, as the
system is purging itself of trapped air. Observe coolant
levels and maintain as recommended by adding coolant to
the recovery bottle.
Coolant (ATP 500)
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 Premium 60/40 anti-freeze/coolant or a 50/50 mixture of
high quality aluminum compatible anti-freeze/coolant and distilled
water. Polaris Premium 60/40 is already premixed and ready to use.
Do not dilute with water. See page 119 for the part numbers of Polaris
products.
NOTE:
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.
