Got another benz, 79 300D with a 134a conversion, yuk! Compressor is noisy just like normal. Getting ready to vent the 134a and convert it over to freeze 12 and BG compressor oil.

The 134a system works but does NOT even come close to the cooling of the freeze 12 I did on the last car.

Stay tuned for more pictorials.....

If I were planning on violating Federal law by venting R134a to the atmosphere, I really don't think that I would announce it on a public forum.

Have a great day,

This thread has been dead for over two weeks but old firestarter is back I see, and now doing other peoples cars or ones to sell. I feel sorry for the owners and techs when they foul up their expensive a/c equipment when servicing the unknown refrigerant thinking it is R134A or R12.

Yes James you're exactly right. I have two recovery machines and it upsets me every time I hear of such activity. There are too many people in this world, however, who look out for their own interests and just figure the devil with everyone else. I can't do such things because I like to sleep at night.

Have a great day,

Not to mention a violation of SNAP.

You guys are really pathetic

Do you really think I will vent the freon into the air???

Of course I WON'T!

I will use the appropriate EPA approved recycling station, just like I did on the other unit. Yes is is UL approved also. Conforming to all applicable laws Federal, State and Local.

So just relax and take a deep breath, it will all be ok.

The idea of converting to freeze12 makes me sick; but it is his car.
I am considering the option of sending him R-12, but will not debate the technical damage that conversion does.
Sad as it is; we must admit he has the right to do anything with the car, even set it on fire if he wants.

Diesel Giant, suggest you ease up on the defense, and do not take it personal.
There are very STRONG technical reasons people are against conversions.

..........why not?

This thread has attacked Diesel Giant for one reason only:

The fact that future service and evacuation of the Freeze-12 is a dicey prospect due to the limitations of suitable Freeze-12 equipment and the potential for contamination of a shop owner's R-134 recovery machine.

There was never any discussion of technical damage to the system using Freeze-12.

If there is a potential for such damage, I'd sure like to be made aware of it, because, AFAIK, the SD has Freeze-12 in the system.

Also, I understand that the pressures of Freeze-12 are slightly lower than R-134A, so, I remain confused as to the technical damage of Freeze-12 when compared to R-134A.

I've got Freeze 12 in my system (it was converted prior to my purchase). With the fan on low speed, the temp is down to 41 degrees (85 degrees outside). When I turn the blower on high, the temp goes up to about 58 degrees....and it has to run constantly on high to try to keep up. Is this typical of Freeze 12?

Thanks..
Keith

Leathermang and LarryBible have said enough in the archives I have read to convince me to forgo the alternatives and use only R-12. The real stuff. But thats a choice I have made based on two guys who have seriously earned my respect over the last couple years here.

You will have to make up your mind for yourself however.

I had to point the vents away from me too. But that was to keep the HOT air off me.

As I have stated over and over, I would have used R-12 if available. I think that given the choice to use 134a or Freeze 12, I will take Freeze 12 anyday.

Now if the naysayers have actual evidence that Freeze 12 is HARMFUL to the a/c system, I will be glad to listen. But my purpose is to get really cold temps at the vent, and 134a is NOT the best substance to use.

I want to be comfortable and have a climate control system that keeps the car cold. I have had many cars with 134a in them, both conversions and factory. My 98 Jetta Tdi came with 134a in it stock and has the coldest a/c I have EVER felt, but it was designed to work on 134a, hence does it well.

I am convenced having worked with both R-12 and 134a systems, that R-12 will cool better faster. So the idea of putting a less efficient 134a substance in an R-12 designed system without making significant condensor/hose changes etc, is not smart. Freeze 12 works great in R-12 systems. Period. There may even be a better substance than Freeze 12 (besides R-12) but I don't know about it.

No intent to rag on anyone.....I just plan on doing this job only once...and I am willing to do the extra work, and the extra expense, and time to get the R-12. Its a personal decision I have made. Just as tire brand and oil type and brand is.

whunter.

Don't send him any of the can I lent you.

Diesel Giant,

Having read all 12 or so pages of this thread, I don't think anybody is having an issue with your putting Freeze 12 in your car. You don't have to change it back.

Just make sure it has the proper sticker, and the correct fittings.

But if you call R-134a toxic sludge, then you put toxic sludge in your system as Freeze 12 is 80% R-134a.
