The 87 bird is much much cooler now. Poor mans A/c overhaul.

After all my troubles I wanted to get the A/c working in my 87. I dug into what the car had in found the HR980 compressor was locked up. Checked and found some charge on the system. Checked at 5psi. So I unhooked everything and removed it and the compressor. Then I took some A/c system flush stuff poured it in and blew it threw all parts. I took one of my many spare compressor J/Y units and checked it out. Swapped out the pulley from the serp belt to the V belt one from the cars compressor. The clutch face was nice and smooth so should work just fine. I bought a Green O-ring kit for R134a and replaced all of the seals. Installed everything in the car. Hooked up a Vacuum pump and sucked the system down. Everything showed good so I took and added oil and then charged it up with 2 cans of Freeze12.  WOW its nice and COLD now. I also don't seem to have any of the warm up in slower in town driving like I've had with R134a in an R12 system.  Total cost $43; the cold air it blows, Priceless in this Humidity!

Loving the Cold air in the 87 Bird.

Just for the record Freeze 12 is 80% 134A and 20% 142B. The pressures are fairly similar and the stuff acts almost identical to reformulated 134A. Just my $.02


@40* R12 is 34 lbs  Freeze 12 is 37 LBS.  And 134A  Is 35 LBS
 So the difference between the freons are absolutely so close it is not even worth talking about. 134 A Has a better oil retention value than Freeze 12. With that said 134A is a better freon in my view. Freeze 12 is just a Blend.

i started from scratch on the Sport and had it converted to 134, glad I did. It works great,and is easy for any shop to tend to in case of an issue down the road. I need it highly functional, yet easy to maintain.

Actually you made the correct decision. We as licensed AC repairers are responsible for the freon we RECYCLE. With all the VOODO freons on the market today we have to be extremely careful. The Fines are outrageous for us. We have to have special tools to sniff out blends and even PROPANE. Yes people actually put PROPANE in AC systems. Vinnie you are 100% correct and RA134A is the best freon for Mobil AC systems at this point. That will change with the new 1234A as it becomes more popular with car companies. RA134A is being phased out as we SPEAK.

It is MIKE the pressure temp tables says it all. Their is actually no difference in temps that could possibly make a difference. Freeze 12 is no longer available. Some may have lingering stock but it has already been reformulated. The best bet is to use RA134A and be dunn with it. People like me that are licensed must recycle this stuff and once again with all the different blends its a NIGHTMARE. If i cross contaminate freons on recovery i have to pay tuns of money to recycle it. If its R12 OR 134A i can recycle it on site and reuse it. Stick with the 134A The other blends are a SCAM. Just my $.02

R407C pressure-enthalpy diagram, isotherms between the two saturation lines

    * R-401A is a HCFC azeotropic blend of R-32, R-152a, and R-124. It is designed as a replacement for R-12.[10]
    * R-404A is a HFC "nearly azeotropic" blend of 52 wt.% R-143a, 44 wt.% R-125, and 4 wt.% R-134a. It is designed as a replacement of R-22 and R-502 CFC. Its boiling point at normal pressure is -46.5 °C, its liquid density is 0.485 g/cm3.[11]
    * R-406A is a zeotropic blend of 55 wt.% R-22, 4 wt.% R-600a, and 41 wt.% R-142b.
    * R-407A is a HFC zeotropic blend of 20 wt.% R-32, 40 wt.% R-125, and 40 wt.% R-134a.[12]
    * R-407C is a zeotropic hydrofluorocarbon blend of R-32, R-125, and R-134a. The R-32 serves to provide the heat capacity, R-125 decreases flammability, R-134a reduces pressure.[13]
    * R-408A is a zeotropic HCFC blend of R-22, R-125, and R-143a. It is a substitute for R-502. Its boiling point is -44.4 °C.[14]
    * R-409A is a zeotropic HCFC blend of R-22, R-124, and R-142b. Its boiling point is -35.3 °C. Its critical temperatiure is 109.4 °C.[15]
    * R-410A is a near-azeotropic blend of R-32 and R-125. The US Environmental Protection Agency recognizes it as an acceptable substitute for R-22 in household and light commercial air conditioning systems.[16] It appears to have gained widespread market acceptance under several trade names.[17]
    * R-500 is an azeotropic blend of 73.8 wt.% R-12 and 26.2 wt.% of R-152a.
    * R-502 is an azeotropic blend of R-22 and R-115.

any idea where I can get a rebuilt compressor for my '85 tc?  It seems all the chain stores come up with the wrong part.  I have the round pancake like compressor, almost like the old GM style.  they keep getting me the big old square comp. like off a mid '70's full size Ford.

Not sure where to tell you to find one, but you need the HR980 compressor. They also made a retro fit kit that swapped to a newer style compressor. You could always try E-bay

Hope this helps
