Cooling System Deaeration

DIAGNOSIS AND TESTING - COOLING SYSTEM OPERATION
Air can only be removed from the system by gathering under the pressure cap. On the next heat up it will be pushed past the pressure cap into the coolant recovery bottle by thermal expansion of the coolant. It then escapes to the atmosphere in the coolant recovery bottle and is replaced with coolant on cool down.

To effectively operate the system, multiple thermal cycles of the system may be required.

NOTE: Operation does not occur at engine idle- higher engine speeds are required. Normal driving will operate cooling system.
