Radiator Coolant - Polaris Sportsman 400 H.O. Owner's Manual

Cooling System

Radiator Coolant

To ensure that the coolant maintains its ability to protect the engine,
Polaris recommends that you drain the system completely every two
years and add a fresh mixture of antifreeze and water.
Replace the coolant any time the cooling system has been drained for
maintenance or repair. If the recovery bottle has run dry, check the level
in the radiator. Add coolant as needed.
Escaping steam can cause severe burns. Never remove the pressure cap
while the engine is warm or hot. Always allow the engine to cool before
removing the pressure cap.
1. Open the front storage box
cover.
2. Remove the pressure cap.
3. Using a funnel, slowly add
coolant through the radia-
tor filler neck.
4. Reinstall the pressure cap.
5. Secure the box cover.
NOTE:
Use of a non-standard
pressure cap will not
allow the recovery system
to function properly.
Contact your dealer for
the correct replacement part.
