2003 Grand Caravan Sport 3.3, rear heating system tubing

Hi
When my Van was on the lift (50000 miles, in Canada lots of salt on the
road), the mechanic noticed that the two metal tubes that carry the
antifreeze coolant to the back heater is starting to rust , especially were
the are there is a little bracket welded to hold the two tubes together. I
am thinking of replacing this before it starts leaking. Any body has gone
through this, and how big of a job to replace. I was also thinking maybe
just cutting off that portion and putting some rubber hoses.
Appeciate any suggestions

Tx

 

Hello:
have it done now, i had a 97' GV and had to have the same thing done
which was causing me to lose coolant.

 

Is it the coolant lines or the refrigerant lines? Neither is
particularly difficult, but the hose patch would not be an option with
the refrigerant lines.

 

How long of a job was it

i have done many rubber hose repairs on those behind the engine with alot less
costly repairs for the customer

 

So i assume you cut off the metal tubing section and replaced it with rubber
hoses
Thanks again

 

yep
in some cases i put split loom plastic tubing over it just to make sure it won't
rub thru
