RE: IML: Smoke on Dash equals Heater Coil leak

["Dick Benjamin" <dickb@xxxxxxxxx>]

The only way I have had these repaired is to replace the core element with
new material.  The old end caps (the miniature tanks that go over each end
of the core material) have to be re-used, however.  A good radiator shop
does this every day, they are really good at it.  They will pressure test it
when they are done, you just bolt it back in and hook up the hoses.

To Dick and list,
dick when you speak of rebuilding a heater core I think you imply that the 
core itself is replaced although soldereed onto the housing????, as opposed 
to soldered to repair the leak?  I had 2 bad experiences with "repair" of 
core and of radiator and have never done anything but replaced with 
newsince, though I am aware that "new" for some of these old gems is near 
impossible.    Please comment.
Regards
JH
