How much freon?
I have a 76 f150 2wd super cab with a 360 and factory ac. It apparently has a leak. When I purchased it the previous owner said it had worked, but recently began blowing hot air. I am in California and will be trying to find someone that can work on, repair and recharge the r12 system. I have 6 small cans of r12. What I am wondering is if anyone knows what the system should hold. Is 6 enough or do I need more?
It is freaking hot, over 100 this week

I cant remember off the top of my head but i know there is a tag (sticker) on the core support that will tell u how much. I'll try to remember to look at mine in the morning for you.
I'm thinking its a little over two pounds.

Keep in mind that if you charge it with 2.75 lbs. of r134a your pressures will be way higher than Fomoco recommended for your system.
I just installed a new compressor on my Crew and recharged the system with r134a. It took 2 lbs. to get the pressures to maximum. I was told by two mechanics that a good rule of thumb is to multiply the recommended amount of r12 by .80 to get a close estimate of how much r134a to put in.
I called and talked to Redtek recently and I'm thinking about ordering some of their r12a to try out.

It's supposed to cool better than either r12 or r134a and run lower head pressures.

That's a good point VocaTexas, but he said he had R12 so I didn't mention it.
I'm thinking about changing out my condensor for a bigger one (maybe upgrade to a parallel flow one), the product you linked too looks pretty interesting.

Ah, I read too fast. In my mind I changed it to 134. I didn't catch that he had r12.
If I were in Kalifornia, I wouldn't tell anybody I had r12 in my possession until I found out if it was legal to have it. They've got some crazy laws out there. Having r12 might be worse than drug possession.

Thanks for the info...yea I am not even sure if I will find anyone to search out the leak, make repairs and recharge the unit, but I at least wanted to know how much it would take if a guy was able to find some.

I need to do some reseach on the law our her in Kalifornia as well. I haven't charged my 87 E-250 for several years due to the price of the stuff. My father-in-law passed away last year and I was told to rummage through his garage and take anything that I thought I could use. I found two 30 pound jugs of R-12 ... one is full and the other is about half. Couldn't find the gages. I'll probably sell the full one and use the rest of the other.

California Police State, Really?
I have lots of R12 and buy it at the old car swap meet all the time. The police are actually there, just to make sure all are safe while us old car folks meander through the rows of used and if lucky, NOS truck parts. I usually find old Freon cans for $10 to $15 each there. No police have ever snuck up on me for buying it and nobody every says anything to the sellers about it. No Police or BAR or CARB have ever followed me home to stake out my place, search it and arrest me for having it.
BTW, I am an auto tech instructor and have had my A/C license since 1992. I am proud to live in CA, where I can come up behind newer diesel trucks and not get choked out of my Shelby convertible.
I also belong to organizations like SEMA and Hagerty who work with government agencies to help keep our old trucks on the road and I write letters and talk with elected officials when issues come up, like trying to move the smog exempt date up to 1981 or so (we lost the last time but it will happen, oh, and I have my CA smog license too).
So peace to all with the goal of more focus on keeping our trucks on the road, no matter what state or country they are in.
