Cooling System Bleeding
WARNING: This page is about a different car, the 2002 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
Air can only be removed from the system by gathering under the pressure cap. On the next engine heat up cycle, the air will be pushed past the pressure cap into the coolant recovery bottle by thermal expansion of the coolant. The air then escapes to the atmosphere in the coolant recovery bottle and is replaced with coolant on cool down. To effectively deaerate the system, multiple thermal cycles of the system my be required. Deaeration does not occur at engine idle. Higher engine speeds are required. Normal driving will deaerate cooling system.
CAUTION:
Manufacturer recommends using only Mopar Extended Life Coolant with a 50/50 concentration coolant and distilled water. This coolant contains corrosion inhibitors that permit extended service drain intervals. DO NOT mix coolants. If coolant other than Mopar Extended Life Coolant is used, service drain interval will be reduced.
