Wait until it is 95 F or more before you expect it to not cycle.

The last time I bought R12 was this summer from a fellow forum member on one of the sites I go to. It was a 54 lb bottle with about 50lbs left. I also bought a r12 can off of craigslist awhile back.

I got my 609 certificate about five years ago which enables me to buy R12 and I had to use it when I bought some R12 on Ebay to recharge my 92 Cavalier.

Check your system by pressures to see if it is low. Continuous cycling usually does mean the system is low but you need to check pressures to be sure.

If possible I would also keep your truck R12 if at all possible if it does need to be recharged or repaired because you won't get the same performance with R134a.

No! Theres no refrigerant that can be added to a system that already contains R12.

The low pressure cycling switch cuts the compressor off @ around 25psi to prevent the evaporator from freezing up. On a cool day it may cycle quite often, on a hot day it may never cycle off.

Also the fan speed has much to do with cycling. Low fan = more cycling and high fan speed = less cycling.

You heard wrong. Nothing has changed and you still need a cert to buy it (legally).

Use gauges like these, mine from the 80's



Your fine for now. Wait till it get in the 90's. Like others said don't screw w/it. Better know A/C, frostbite can happen

Where would I get the guages though. I noticed the line gets cold but when clutch kicks on it gets even colder and when you shut it off it makes the equalizing pressure noise. My Saturn doesn't cycle when it turns on its on. The truck is every 7-10 seconds . I may end up converting all the r12 stuff seems hard to get a hand on

Is it still cold in the cab? It needs to cycle to not freeze up!

Yes it is still cold. Why would it cycle every few seconds and the Saturn didn't do it in 3 minutes? I imagine the system is low. That's what I'm thinking. If I convert it I will do it myself. Will I need to drain the oil and put in new? Or just replace refrigerant?

Your saturn has a variable displacement compressor . It won't cycle like your truck with its r4 compressor does. Completly different compressor designs.

Your over thinking it. My '89 Olds uses schaving (sp) extra gasses routed. Never cycles, always on. Don't use the modern for your older truck.

As too R12 I bought before the ban. Only used 15lb in 20 years. 3 R12 users. Wish I never had a garage sale of my R12 cans.. Only got $7 a piece back in 1998.

So its normal for it to cycle every 7-12 seconds? In 50 -60 degree weather.
