A/C Lines ??
 

With the Chevelle close to actually doing the painting I am wanting to clean up the radiator support. Can't get the pictured A/C line to come apart where the screwdriver is pointing. Have the threaded nut loose and pulled back, problem is the line won't seperate at the connection. Have tried a gentle twisting and tugging motion with no luck. Anyone had this problem with their A/C lines before? Maybe PB Rust Blaster and heat? Not a torch, maybe a blow dryer on the low or high setting? Don't want to melt the line, LOL Any ideas ??

That part of the tube is a formed little collar with part of the tube going in. Put some kind of penetrating oil on there, let it sit and tap with small hammer.......should come out.

Ken, tried using PB Rust Blaster on it, hand tightened the female portion to the male portion of the threaded nut/coupler. Tapped on it with a small 8 oz. ball peen backed up with a 1'' square stock solid bar. No luck at all, can't fit get a thin knife blade between the flanges to start a separation going. Am I hosed on this, alternatives? Need to get this separated to clean up the radiator support for paint. Will try using an actual heat gun next time, ran out of time today.

Finally was able to seperate the A/C lines, don't hink it will help me much tho. Inside of the lines look pretty rusty/crusty/nasty. Not sure they will clean up enough to use after a flush. Also found out I am missing a LH lower condenser to radiator support bracket. Always something unexpected, huh?

Sounds like a log of condensation got into them is why they rusted

Removed all the brackets and such from the OEM 40+ year old condenser today. Just for giggles, blew some compressor air thru the lines and shot a 3' cloud of Sahara or Mojave out the other end, LOL. Thinking this is not going to be good trying to rebuild my original factory AC. Starting to think about going with an aftermarket complete system, Classic Auto Air, Vintage Air or Old Air? Does not have to be a stock look , just don't want a lot of chrome and flash, more OEM looking is fine. Just want good COLD AC, sufficient heat in the fall, (winter, the Chevelle will hibernate in the shop) and the ability to defrost front windshield for a cool fall drive before the long winter's nap.

Thoughts from any and all are appreciated.

A/C condenser
 

I have a working 71 A/C condenser from my 71.Bowtie smiley I removed it when I installed a 70-72 Paralell Flow from the Fla. Guys. It is in the box that the P. Flow cam in. This condenser was clean and working when it came out.

Thanks for the offer but have decided I will replace the entire A/C system with a complete setup from Vintage Air. Probably will do that next year as the wallet is pretty well FLAT from doing the paint/body thing. Restoring this Chevelle is more $$ than when I restored my '71 Chevy 4x4 long bed pickup.
