I have an old post on this somewhere.
Everyone who has a LWB Chrysler minivan should take note, that these things need to be inspected regularly, and you should plan to replace them probably every three years. The last time you replace them, if the van is really old, you can just plug up the heater hoses behind the engine compartment and save yourself the trouble.
I was shocked to learn in about 1998 that the rear heater tubes in my 95 were almost rusted through. The shop that had it, let me know that this was happening, and replaced them for me. In the 2nd gens they were MUCH shorter than these ones, and it still ran me upwards of $200 for the part. They came as a unit, I think they are connected to each other with the piece of metal that connects to the underbody.
Last year, I observed that the rear heater was leaking. PRobably because the hose between these troublesome tubes and the rear heater core was the original. This hose is impossible to get to. One of those areas where they designed it well, for assembly, but not for service. So I just looped the heater hose around rather than running heat to the rear. I could drive the van with much more peace of mind after that.
My other post, I think is in the Wishing Well, from months ago--to make these rear hoses out of something that will not corrode away. DUH!!!!! Or at least shield it somehow with a hunk of thick plastic.
