Cooling System; Recovery Bottle Coolant - Polaris Sportsman 400 H.O. Owner's Manual

MAINTENANCE

Cooling System

The engine coolant level is controlled, or maintained, by the recovery
system. The recovery system components are the recovery bottle, the
radiator filler neck, the radiator pressure cap and the connecting hose.
As coolant operating temperature increases, the expanding (heated)
excess coolant is forced out of the engine, past the pressure cap, and into
the recovery bottle. As engine coolant temperature decreases the con-
tracting (cooled) coolant is drawn back up from the bottle, past the pres-
sure cap, and into the radiator.
NOTE:
Some coolant level drop on new vehicles is normal as the system is
purging itself of trapped air. Check the coolant level and maintain as
recommended by adding coolant to the recovery bottle.
Polaris recommends the use of Polaris Premium 60/40 anti-freeze/cool-
ant 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 121 for the part
numbers of Polaris products.
NOTE:
Always follow the manufacturer's mixing recommendations for the
freeze protection required in your area.

Recovery Bottle Coolant

The recovery bottle is located
under the front storage box cover
near the radiator cap. Maintain
the coolant level between the
minimum and maximum marks
on the bottle (when the fluid is
cool).
1. Position the vehicle on a
level surface.
2. Open the front storage box
cover.
3. View the coolant level.
