I just got my freeze 12 a couple days ago, and I wanted to use it, but it didn't come with any instructions. Can anybody help me? I got a kit that has 3 12oz cans of freeze 12, 1 4oz can of oil charge, 1 4oz can of stop leak, 1 Duct discharge air temperature thermometer with pocket clip, (0 to 220 deg. F.), 1 can taper with a inline gauge.

i found those videos when i was trying to figure out how to recharge the a/c. They're basic but I found them helpful as I had never done work with and a/c system. The videos use r134a but its the same process with freeze 12.
Oh and good choice going with freeze 12. I've been very pleased with it so far.

How do you know how much freeze 12 to put in, and what about the stop leak and oil charge? How much of those would you need to put in?

also, the kit came with a freeze 12 to r12 adapter, but the adapter is too big for the r12 low side thing on the car.

should be listed in FSM available in the FAQ.

Also a good practice is to replace the o rings in the entire system

Got a question, Do you have to have a license to buy Freeze 12? There is only one place in my town that sells it, and he said that I have to have a license to buy it?? Is this true?

why does it look like there are two different low side valves? upper left and lower right in the pic. both are same type of valve.

porsche4786

you can buy freeze 12 legaly except in wisconsin i believe. i got it off ebay. the guy also sells r12 but you have to give him your license number.

tinvestor

yeah pay like $75 per pound

The thin line is high side.

Is the system empty?

porsche4786

no, the air is still cold, but mostly just on the freeway when i'm crusing. probably a little low.

edit: now why would they go and put the same valve for high and low. seems like that is a dangerous thing to do.

People are expected to be certified to handle refrigerant and a certified person knows which side is which.

I am not all that familiar with freeze 12 make sure to read the directions it needs to be a direct replacement, I am pretty sure it is but read. Before you can add the appropriate amount you need to reclaim the system and add the right amount you can use a scale to add it if you find how much is needed. Obviuosly it must be a very accurate scale. Or you need gauges and thermometers including a wetbulb thermometer to calculate superheat to properly charge the system.

Quite a few people on here have used freeze 12 from when I can see, but not much info on actullay putting it in. I see in the fsm 14-24psi, but the guy I got the stuff from says 35-45psi. it does have a gauge on the line. and the kit did come with a thermometer. i think i'm going to see if i can get a reading on how much pressure is in it right now. What is the point in having the car running? In the FSM they use R12 and I dont' see anything about having the car running. Is this because they have professional equipment?

Secondmessiah

my adaptors for freeze12 are different for highside-lowside, the threading is even in opposite directions

do you really have to change hte reciever dyer when converting?

tinvestor

Yes you should change the receiver

I didn't check the psi yet, but I just checked the temps with the engine idling in my driveway. with just ac on i got 56 degrees F, and then I closed the windows and put it in recirculate and got 50 degrees F. Maybe that's just how it is.

edit: i just checked the temp on our 2004 chevy pickup and got the same temps

tinvestor

The operating pressures of different refrigerants vary that is why 12 (with the car running) should be 24 and freeze 12 is 35-45 however that is a REALLY big range the best bet would be to run the car charge to 35 check the thermometer in the vent and add (very slowly) till the temp goes up instead of down you must wait 3-5 minutes between chinging pressure by one pound.

I ordered freeze 12 and just attached i to the high side against the firewall. It too less than 1/2 a can to fill and my car has been blowing cold erver since. this was 3 weeks ago and no problems. Just let the car warm up and then put the frreze 12 in slowly. All i did was attach it to the fitting and let her go until it was blowning cold. Hope this helps and you can PM me if you have aqny questions.

sounds like a diff process, guess that why I never bothered to refill my a/c. Would be nice to have being its been 97 degrees and humid here in Vermont. On hot days I just drive my other car that has a/c :p

tinvestor

I think 50 degrees is well within factory specs so I would not open a system that is in good condition. This just opens the door to problems.

To my knowledge Freeze12 is a direct replacement. You shouldn't have to change the reciever/drier, thats just with r134 conversions. I had a shop fill mine up with freeze12 in my MX-3 (it was already in for A/C problems) and they said it was a direct replacement.
Its not a difficult process to add refrigerant. From what I remember, you basically clamp on the bottle, start the car, and fill to the desired pressure.

I think it just took a few times of use for it to get back to normal.
