2005 Chrysler Sebring
Low heat out of vents (80). Just did a motor swap not sure if all the air was bled out of system. All inside controls seem to be working like normal. Temp into heater core 156/ temp coming out of core 136 with a new 190 thermostat. Is there a special procedure to bleed the air out of cooling system.

  1. Not really special but it does sound like your thermostat is either stuck open or you may have an air pocket as you stated. Run the engine until it gets hot and the thermostat opens. Then you can top off the coolant level. I show that the 2005 came with a 3.0L V6 not a 2.7?

  2. The thermostat is new and the car does have the 2.7. The car runs at normal operating temp when warmed up. I have flushed the heater core both direction and the water runs clear with no restrictions. I have replaced the control unit because the temp knob was working the blen door acuator. But still only about 80 degrees of heat coming out of the vents with engine at operating temp. I,m told that this is a commen problem with these cars. I thinking about an air block in heater core but don,t know the procedure to bleed it.

  3. Now I see. Let me get you what you need to take care of that.

    Bleeding procedure for Chrysler Sebring – 2.7L cooling system

    1.Close radiator draincock by turning clockwise.
    NOTE: IT IS IMPERATIVE THAT THE COOLING SYSTEM AIR BLEED VALVE BE OPENED BEFORE ANY COOLANT IS ADDED TO THE COOLING SYSTEM. FAILURE TO OPEN THE BLEED VALVE FIRST WILL RESULT IN AN INCOMPLETE FILL OF THE SYSTEM.

    2.Open cooling system bleed valve (Cooling System Filling – 2.7L).

    1 – SPECIAL TOOL 8195
    2 – COOLING SYSTEM BLEED VALVE
    3 – PINCH OVERFLOW HOSE
    4 – COOLANT PRESSURE CONTAINER

    3.Attach a 6.35 mm (0.250 in.) inside diameter clear hose that is 120.0 cm (48 in.) long to the bleed valve. Route the hose away from accessory drive belts and radiator fan. Position the other end of hose into a collecting container. The hose will prevent coolant from contacting accessory drive belts and other components.
    4.Remove cooling system pressure cap. Attach Special Tool 8195, Filling Aid Funnel to coolant pressure container filler neck.
    5.Use the supplied clip to pinch overflow hose that connects between the two chambers of the pressure container (Cooling System Filling – 2.7L).

    4 – COOLANT PRESSURE CONTAINER

    6.Pour coolant into the larger section of Filling Aid Funnel (the smaller section of funnel is to allow air to escape).
    7.Slowly continue filling until a steady stream of coolant flows from attached hose on bleed valve.
    8.Close bleed valve and continue filling system to top of Filling Aid Funnel. DO NOT overtighten. TIghten to 12.4 N·m (110 lbs. in.).
    9.Remove clip from overflow hose.
    10.Allow coolant in Filling Aid Funnel to drain into overflow chamber of pressure container.
    11.Remove Special Tool 8195, Filling Aid Funnel and install pressure cap on pressure container.
    12.Remove hose from bleed valve.
    13.Start engine and allow to run until thermostat opens and radiator fans cycle.
    NOTE:

    The engine cooling system will push any remaining air into the pressure container within about one half hour of normal driving. As a result, a drop in coolant level in the pressure container may occur.

    If the engine cooling system overheats and pushes coolant into the overflow chamber of the pressure container, this coolant will be sucked back into the cooling system ONLY IF THE PRESSURE CAP IS LEFT ON THE PRESSURE CONTAINER. Removing the pressure cap breaks the vacuum path between the two chambers of the pressure container and the coolant will not return to the cooling system.

    14.Shut off engine and allow it to cool down. This permits coolant to be drawn into the pressure chamber.
    15.With engine COLD, observe coolant level in pressure chamber. Coolant level should be within MIN and MAX marks. Adjust coolant level as necessary.
