What Impact Do Insufficient Coolant Levels and Air Entrapment Have on Heater Core Efficiency and Engine Temperature on 2003 Chrysler Voyager?

The position of the rear heater core can lead to coolant problems and air entrapment, which can result in overheating and poor performance. To avoid this, fill the core with coolant before reconnecting hoses. After refilling the engine cooling system, make thermal cycling and check rear heater performance, make sure air temperature is between 57deg to 63degC.
