Bleeding the Cooling System

WARNING

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.

NOTICE

Severe engine damage may occur if the cooling system becomes restricted or plugged or contains trapped air pockets.

Perform this procedure in a well-ventilated area. Use the recommended coolant. See Coolant.
