Thanks for the info Manny. I knew someone had to rebuild those old heater cores.

 

New to this forum. Has anyone used a rebuilt heater core from Lefty's? I have this same issues and have been quoted the same kind of prices and don't really want to go through the entire conversion to new system if the rebuilt option works fine. Appreciate any feedback on results of rebuilt cores from Lefty's. Thanks.

 

I haven't. So far the 97 has hung in there. Maybe someone else on here has as it is a common problem.

 

I have done both on my 94, Lefty's and the late model upgrade. On the first failure the Lefty's unit started leaking so I had a local guy take it apart (which is not an easy thing) and repaired it. The a year or so later I did the nice upgrade while I had the truck apart for an engine transpant.

The original HVAC units in the 94-97s are complete JUNK. I have nothing bad to say about Lefty's or the unit I got from them, but... in my 16 years experience as a rebuilder, no matter how good you are, you just can't make sh*t shine.

So really your choices are this:

1) Spend under $1k and repair a system that really doesn't work very well even in its best condition and will very likely go out again at some point;
2) Spend big bucks for the ugrade system which works much better, is more reliable, and easier to repair.

I took the cheap route the first two times and for me it didn't work out.

Something else to consider is if/when you sell your truck, knowledgable lookers will be checking for the upgrade and will value your truck accordingly.

 

Hi Scot. Good to see you here.
