My 92 chevy truck has r12 and boy o boy does she get ice cold. My problem is the ac clutch cycles every 20 seconds or so. I assume it needs freon. Now I really dont want to convert it:( 134 sucks. Isn't there a can of freon made that can be bought by a regular Joe and is compatible with r12?

I think ebay would be a good choice for cans of r12, they can be pricey though.

Craigslist normally has a few. The price has really come down now that most cars on the road take R134a.

everytime I buy r-12 from ebay the seller wants to see a copy of my license first.

I got cans R-12 off of Craigslist. Keep checking. They come up here in Spokane all the time. My 93 is ice cold too.

R12 hasnt been manufactured for over 10 years now.You need a licence to buy it.They dont want you purging it into the atmosphere,you need the reclaiming equipment and licence to deal with it properly.

You need to go by the pressures, not if it cycles every 20 seconds. What temperature are you running when testing it?

Leave it alone! Overpressure can make the clutch cycle just like under pressure. You say it's cold. Don't touch it!

A gauge set might be useful, but every time you connect one you vent a smidgen of that precious R12.

If it is ice cold, leave it alone. You do not need a recharge IMO. The clutch is designed to cycle. You are lucky your '92 Chev is still tight. These systems were designed for R12 and to convert it when it is still working is a waste on money. FWIW--Oldtommy

Don't mess with it. If it's cold leave well enough alone. As was said, when you connect to the system you lose some refrigerant. Not a lot, but since auto A/Cs contains little to begin with it makes a difference.

Wait until it is a hot humid day and run it for a while. If it is cold, and the suction line is real cold then it is full charged, and you do not want to mess with it. On cold days like not the clutch should not say in. The clutch should stay in on hot days.

Last I heard, you don't need a license to buy it anymore.

Even if you do, the online test takes like 5-10 minutes and you instantly are "licensed". Did it myself some years ago.

Its about 60 degrees outside and it cycles about every 10 seconds. It seemed like longer. Its very cold colder than my Saturn and I know it works correctly
