Polaris 400 H.O. Offroad Vehicle User 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.
CAUTION! Escaping steam can cause 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 box cover.
2. Remove the access panel
screws. Squeeze the outer
edges of the panel inward to
remove the panel.
3. Remove the pressure cap.
4. Using a funnel, slowly add
coolant through the radiator
filler neck.
5. Reinstall the pressure cap.
Use of a non-standard pres-
sure cap will not allow the
recovery system to function
properly. Contact your dealer
for the correct replacement part.
6. Reinstall the access panel and secure the front box cover.
