Chrysler Repair: Rust/corrosion on rear heater coolant tubing: 99 van, plymouth voyager, postal mail

Question
Hello Roland,

I have a 99 3.3L Plymouth Voyager. This past Sunday after church I came out to find a giant puddle of anti-freeze and just hoped it was not mine, hehe. Anyway after driving off to our home 5 min away, I noticed I had no heat, GGRRrr! It was me. I got home just before the needle reached the red zone. I Drove it up on ramps.

I added water and checked under to see where the leak was. It was the metal tubing that connects to a rubber hose just under the pass door, it was corroded. I picked at it and saw it was frail. I decided to hack off 3", removed the rubber hose & replaced it with a bit longer one & used 2 screw on clamps.  

Hesitant about loosing expensive anti-freeze I added water again to test the repair. 20 sec's after I started the engine it began to pour cats & dogs! I dropped down and looked up, it was now coming from the metal tubing further up just behind the engine. A rip in the rusted line.

I was searching online for an idea on how to replace these two lines, as I saw it seemed very difficult to do.

What method from any two, would you advise me to use, to replace these lines? I'm also trying to find a schematic or photo of this work area, do you know of any? Thank you.

Answer
Hi Johnny,
My '98 shop manual shows the connections up front and has a short section that describes replacing parts in that area. I would be glad to xerox copy and postal mail those couple of pages to you if you will give me a postal mailing address via the "thank and rate" tab where there is a place for comments. Additionally if you went to a dealer parts department they will no doubt show the area in detail in their parts catalog from which they can easily print out the schematic views because the entire catalog is on their parts computer. With all that as resource it should be possible to buy the replacement parts and install them to original.
