R152a - A/C alternative fill... (Page 2/6)

I still don't know why you need A/C in Canada. Too used to cold I guess.

As much as I hate walmart, they have 134a right now for $4.88 a can, that's cheaper than the flammable duster spray.

I still say if you are going to risk a high flammable refrigerant may as well use propane/butane (butane is needed to carry the oil as propane won't do it alone.) and works as good as R-12.

Been 75°F - 85°F since about the beginning of May or so in my neck of the woods - only the very odd time has it been below that during the day time. Sure maybe not Nevada hot during the summer, but I hate it when the igloo melts. lol

It is all what you are accustomed to.

Not even available at Canadian Walmarts. R134a is not available at retail in Canada.
Only "certified technicians" at a shop have it because of its GWP (Global Warming Potential).
That's why R134a will be phased out...

I am somewhat embarrassed to admit after *years* of thinking about that Envirosafe stuff I finally gave it a go in my 1993 motorhome. That system uses R12 but I needed a quick, cheap fix and since the system was already questionable, Envirosafe got the green light.

Three years later it's still in there and the system works great. I don't have any other R12 systems - the Fiero, Saab, and XR4Ti have all had their AC systems removed, everything else I have is R134a - but if I did, I'd use it again.

Every quantitative test I've ever read shows that HC-based refrigerants are no more susceptible to burning than R134a in real life. Turns out the entire R134a sales pitch - won't burn, won't deplete the ozone - was grossly overstated. No surprise, it was a pitch to the US Government and I'm sure Dupont Corp. had a lot of cash to grease the system. They stood to make a lot of money with the approval. And they'll make all that money again with R1234yf. Lame.

Daimler Group will not be using R1234yf. They contend it is flammable.

I'm not sure if this is their test video. It's German, and R-1234yf is the subject.
It appears in a car fire, the compressed A/C gas can then be explosive when heated.

I believe that the stuff that the online hawkers sell as an R-12 replacement is called Enviro"safe" which is butane. Butane is an efficient refrigerant and works well until it ignites. There are some very nice fires in cars using butane A/C systems on YouTube. That plant hat canned "envirosafe" blew up. The side of a factory with brick walls was blown off as was the roof. That's on You Tube as well . As for R-152 is that LP gas as well???

Yahoo! A/C system still working fine.
It is blowing SO cold it can freeze you out of the car…
It appears I had finally fixed ALL the leaks once and for all.

When I dropped the cradle to replace clutch/transmission,
I found a cracked tube in the hose at the compressor end. Got that welded.
And I replaced all the O-rings in the system with the correct ones this time.

Many thanks to RWDPLZ for the part numbers

134 has been selling at Walmart for $3.55 a can for the past month here. might be the time to stock up. Even if the 152 CAN be used in older cars, you KNOW the price will be way Up.

A 30lb cylinder of R134a costs $69.99 at my local Rural King (farm store). That equates to $1.75 per 12oz.

I've run R134a in my Fiero for years. Blows 34 deg F out the vents - verified by a thermometer. Why would I replace it?

R152a, as it boils - is easily ignitable, producing a very large blast of flame and extremely toxic gases such as hydrogen fluoride and carbonyl fluoride as combustion products. Keep in mind the refrigerant in your Fiero boils off in the evaporator core, which is inside the car with you. You can run it if you want, but I won't.

Furthermore, if you put that stuff in your car and don't tell a shop you are running it and they service your system with R134a equipment - YOU are going to be on the hook for decontaminating their servicing equipment, and paying for the disposal of their contaminated holding tank. Have fun paying that bill!

I suppose we could use this product like this with HFC-134a

Or this...
