    Heater pipe under van rusted out! Arrrrgh!!!

    The freakin thing blew out on me going home tonight. We were almost home when I noticed the temp. gauge hovering just below the red, but not climbing any more, yet. At home, popped the hood and both fans going to beat the band. Crawled around underneath with my flash light, and there it was horror of horrors, anti-freeze still kind of pumping out the hole in the steel pipes at the location around the welded on bracket. Shut off the engine, still not in the red yet, check coolant resevoir, bone dry. CRAP!
    Does any one know the approx. cost of these pipes (in Ontario Canada)! Has anybody ever had the pleasure of replacing them. I do need the rear heat for the little tykes on the long winter trips up north to -40 Deg. Celsius land. Any info would be appreciated. It is my 2001 Grand Caravan by the way. Thanks. I am almost too petrified to call the stealer for pricing.

    Repair

    I had that happen to me, I replaced bad section of metal pipe with high quality heater hose and 4 screw clamps.
    Not hard to fix.

    While it is strange that it happened on that new of a vehicle, Bernard hit it on the head. Just make sure it is connected to the underbody correctly so it does not droop or fall.
    Do they salt the roads where you live, during the winter?

    By the amount of salt they use here, you'd think the automobile manufacturers likely pay for the salt to generate revenue. Most new vehicles are beginning to rust before they leave the dealer's lot.

    Salt, yes they love the stuff hear. I am a little leary of non OEM fixes, especially for the enviroment this will be used in, the north country is hard on vehicles up there. I will call the dealer today to get a price on the replacement tubes for the shock of my life. Thank you for the input so far, it is appreciated.

    Uh-oh, I'm getting plenty nervous. There's more salt on the roads around here during the winter than there is pavement...I'd better have a peak underneath the Caravan...

    The rubber hose suggested might actually outlast the metal pipe that is currently being used. Metal will rust again. I'd certainly make sure that your new pipe is insulated with rubber or something that will not let the salt through.

    Those pipes down there are just BARE STEEL? I always made the assumption that they were stainless or aluminum or something other than bare steel. Even though we live in North Carolina, I'll keep up my underbody inspections. Thankfully they're pretty modest with salt around here. We get a lot of ice, but they typically sand before they salt.

    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.

    The rust on the underside of my 02 T&C is out of control. The pipes, rear axle,springs and all hardware are rusted to the max. It reminds me of a sunken ship wreck on tv. I have never owned a vehicle or seen one that is this bad for rust build up. My seat tracks are even covered with rust. I am having second thoughts in keeping the van because of the rust buildup. If you remember from old post I had to replace the tailgate for rust problems. If I replace the pipes and keep the van I will check into getting them power coated before I install them on the van.
