As he requested. Info on Substitutes, i steered him away from the blends.
I also stated that the system needs to be Diagnosesd first to determine why it's not coming on or not blowing cold.
I also informed that R12 is the most effective for his vehicle but obsolete. Also that the shop he takes it to does not have to replace all kinds of things just to change to R134.
R134 is the currecnt freon used in Todays vehicles at this time. The japaneese systems
have no problem being changed to R134, they work quite effective.
The advice is given because the obsolence of R12. He has stated that he does not mind spending extra money on R12. Thats fine, but he also mentioned that he heard there may be concerns about R134a. Fact is there are no concerns about using R134a in his particular vehicle.
It is also true that no one was able to refer a shop. Maybe that is because no one has found or feels comfortable with one in the area. However thats all he has to do is look in the phone book under Automotive. Find someone that has a huge ad on A/c. Call up, ask some intelligent questions and determine what course of action you want to pursue.
Calling a member retarded is asking for a major flame job.
What's wrong with us guys statement. Excuse me,"what the hell is wrong with you guys".
I guess we are so used to trying to "Help" our fellow members save money and advise them on "Current" procedures and the benefits. We forgot to be a "A___hole!!!!
I recommend that you turn your A/c on Max air and chill in your Smokey and the bandit
vehicle and save your hostility and energy towards something constructive. Like coming up
with some new mod for our 7's. Otherwise Doc is going to have to prescribe a Extra dosage of Prozac for you.

 

The whole conversion takes about 5 minutes. Just screw a nipple on, and your ready to go. Also I went to one of our local shops and they said it would be between 700 and 800 dollars to recharge my car with r12. What a joke. Just by the kit. It is super simple take about 20 minutes and you will have ac again.

 

R134a is not as efficient a refrigerant as R12. Your stock A/C setup is not meant to use R134a, therefore it will not blow cold. R134a has a lower critical temp than R12. R134a is 214F and R12 is 234F. I don't think I would want R134a especially on a rotary. It liquefies at that temp. And you don't think your car does that in standing traffic? Being the A/C is next to the radiator? If you are in 90-100 deg temps, it will hardly cool you off. Maybe 60 deg F blowing out at best. R134 conversions are crap on stock R12 A/C systems. A larger condenser for a R134a charged system might cool it down better, but it still won't be as cold as a R12 charged system.



I converted my truck to R134a and I will never do that conversion again. The A/C sucks now. R134a is an inferior refrigerant than R12.


If you want to save money and have crappy A/C, then so be it.

 

if you use 134, throw in about 2-3 oz of propane...it gets that **** COLD

 

Just open the freaking windows. It will benefit you both ways. loose some weight and saves gas at the same time.

 

actually, having the windows down uses more power than the a/c at freeway speeds because of the extra drag.

you want that f10? it's got the msd boxes and coils...ready to go.
it's a dinosaur, so i figured you'd be down.

 

not ready for that yet. Im working on my blow-thru and my son's FB so we can terrorize the Silverlake area with our loud cars.

 

any time you're ready for it pops.

i need monies.

 

I've purchased a new compressor as a back up. My 94 currently does not blow any cold air....(more like warm)~ on the new denso compressor made in japan showed model number HFC134 and said use only ND oil 9. Would someone explain this? Does that mean this compressor is ready for R134?

 

Well, that local shop was trying to rip you off (or else they were not certified to recharge with R12 and wanted you to convert). A full R12 recharge should be about $150 inlcuding labour and the R12 itself.

There is this persistent myth that R12 is really hard to find and super expensive. It is not. Cans can be readily be found eBay, for example. Yes it costs about $20 per can versus $3 or so for R134a, but you probably only need a single can to top up - at most an entire refill of an FD will be three cans, which is $60. On an FD $60 is noise.

There are several other myths:

. If a shop finds a leak in an R12-equipped system, then they have to drain all the R12 and convert it to R134a. This is hooey.

. If the shop finds a leak in an R12-equipped system, they are not allowed to recharge it. Again, hooey.

There is no good reason to convert an R12 system to a R134 system.
