    1996 Marathon over the road air

    Posted by Kenneth on February 25, 2023 at 4:39 pm

    I have a 1996 XL Marathon, The coach has their version of over the road air. There is a device in the engine bay above the doors. This device connects the high side and low side Freon lines together. I think it is some kind of metering device? Does anyone know what this device is called a part number and the purpose for it?

    Thanks Ken Murphy

    That looks alot like a POA valve GM used in the 70’s.
