Polaris 800 INDY XC 129 2019 Owner's Manual page 113

FLUSHING THE COOLING SYSTEM
To ensure that the coolant maintains its ability to protect the engine, we
recommend that the system be completely drained every five (5) years and fresh
Antifreeze 50/50 Premix added. This service must be performed when the
engine is cold. Your POLARIS dealer can check the coolant when performing
the fall tune-up on your snowmobile.
BLEEDING THE COOLING SYSTEM
Steam and hot liquids will cause burns to your skin. Never bleed the cooling
system or remove the pressure cap when the engine is warm or hot.
Use of a non-standard pressure cap will not allow the recovery system to
function properly. If the pressure cap needs replacement, contact your dealer for
the correct part.
Severe engine damage may occur if the cooling system becomes restricted or
Perform this procedure in a well-ventilated area. Use the recommended coolant.
See page 110.
