I changed the alternator yesterday. To access the belt, I had to remove the air cleaner filter box. When I went to put things back in, there was a hose on the back side of that box that was unhooked and I couldn't find where to attach it to, can you help?

Hello COACHLEE17,

Looks like this hose goes from the Air Box to the Positive Crankcase Ventilation valve (PCV) located on the intake manifold at the rear of the left cylinder head.

It is called a "Makeup" Air Hose and provides fresh filtered air to the PCV system.

I have included a couple diagrams for you.

I also found the Dodge part number for the hose for you in case you need a new one.
Part number: 53013886AB

If you need or want to replace the PCV valve as well, here is the part number for that:
53034065AA

Let me know if I can provide any additional information.

Thank you,
Brendon
