Sub dual a/c problem
 

My 72 sub dual a/c system won't hold freon. Leaks out in 2 -4 weeks. Used dye. No leaks found. Anyone had a similiar problem? Is there a "likely" place to look? This things got me frustrated!

did you check all along the hoses going to the back? Rubber hoses run under thet ruck and then up through the paneling on the passenger side

I found a leak in one of the hoses running underneath, the "holding" clamp weakened and had rubbed against the drivshaft. I probably would of noticed the sound except my stereo's too loud:uhmk:

Thanx for the info, but I've checked the lines as much as is accessible. Thanx to some one else's problem that I read about, I am familiar with the routing of the lines. I don't look forward to having to replace those lines.

I replaced my lines a couple years ago. It is not very hard.Remove the door panel and side panel,and you will have no problem.

Who makes the lines runnin to the back?

Id like to replace mine!!

Re: Sub dual a/c problem
 

I bought mine online from ackits.com. You buy it in bulk. I reused the factory hose ends and clamps. I also used Nylog O-Ring Lubrication to coat the fittings and orings. It helps to seal them. I have not had any problems with leakage.

If you cant's find a leak with the dye it may be one of the evaporator cores leaking inside the a/c boxes. best to access the boxes and make sue it is not an evaporator. The dye will find it's way out with the freon.
