Chevy C10 R134a AC Retrofit

In this video I retrofit my 1975 Chevy C10 to convert from R12 to R134a AC refrigerant. The steps involve flushing all the old oil out of the system, installing new o-rings, new drier and orifice tube, adding oil and R134a refrigerant.

You havto take out the Schrader valves from the existing R12 fittings! Good call! Nobody else explains this.

Best of luck!

@@bluesxt went well. I ended up having to replace condenser. But it held vacuum after changing all the orings, and it’s blowing ice cold tonight

@@dakotahcollins1630 glad to hear :)

You need to flush all that old oil out of everything id replace the compressor and condenser and get one for R 134

@@jbncnow I did flush all the old oil out (as much as I could with what I’m working with) :)
A new parallel flow condenser is not a bad idea. But I will say after reusing the existing compressor and condenser, it cools just fine. It’s not ice cold, but it is comfortable

Good video man! Where can i buy the conversion kit for my 1986 c10?

[@bluesxt]

Search for an ac receiver drier kit for your c10. You’ll want a drier, an orifice tube and orings. That is standard stuff for any time you do ac work to your vehicle. The conversion kit you can find on Amazon for cheap, just search for r134a conversion kit. And then of course you’ll need to flush the ac lines and then add some sort of r134a compatible oil

They're banning 134a, so you'll be doing this again with some other refrigerant soon.

not correct that’s a ban for new vehicles 2020 and newer saying you can’t use it on new production vehicles. it’s available anywhere in cans

@@Reaglesracing44_ Banned in Washington state as of 2021, the Home Depot just got fined 1.6 million for selling it over counter. Its banned in other states too. It will be banned in all commercial AC units in 6 months, Jan 1 2025. And it will continue, just like R12 did.

​@@Reaglesracing44_it will be around for a few more years, but yep, it's on the lost to be banned. I thought 134a would stay the r12 replacement, I think it's more about them making money. Starting in 2021, cars had to start using 1234yf. It's much more expensive. Even refrigerators have moved away from r134a. My option it was an ok refrigerant, it was the "safe" refrigerant to replace r12, now they claim the safe refrigerant isn't safe. It's all about money.
