all of this is not needed.. all you have to do is remove the compressor and drain the mineral oil out,, then add 4 oz of PAG oil.. vacuum system down, leak check. then get an r12 to 134a hose adapter, and fill it with 134a ,, the oil change may nor even be totally needed.. when r134a first came out I put it in a freezer that took r12.. the freezer has been running flawlessly for 17 years now.. alot of things in the refrigeration industry is scammy.
Pag oil actually evaporates and mixes with r134a and moves through the system. Where is mineral oil does not and doesn't mix with r134a. In a small AC system there's not much distance that the oil needs to move to keep things lubricated, but in a vehicle AC system that oil has to move throughout the whole system past the compressor converting back into a liquid to lubricate the compressor. With mineral oil it will not reach the compressor
Thank you, that was a very good video. Answered all my questions about parts needed to finally do the job right. Badass job describing the parts and what the install process would be like. Will look for a Drier that is forward facing. I have a 1993 Chevy S10 Blazer Tahoe LT w/4.3 Vortec.. good engine, just has the damn R12 components. I Was going to try a kit that's supposed to let you recharge w/out replacing parts, some kind of R12 to R134a kit, but you inspired me to just do it right. Good camera shots and talking points too 👍
Thank you for the kind words and for the viewership. I didn’t find any videos that tickled my fancy when I was going through the process so I had a duty to make as good of one as I could.
I ended up having to convert my 97 dodge to carb because they don’t make a proper crank sensor for the 5 speed stick model v8s anymore and had to relocate the a/c compressor. I ended up fab’in up an idea to run the compressor off a 5amp Clothes dryer motor, mounted remotely. Cool part is I can run it without the engine running. Engine bay is huge so I could mount the remote compressor on the passenger side of the engine compartment.
Could i get a complete parts list for this, please!!! It's hot here in Texas lol, and my 88 on r12 aint doing it. Just like you, im having a hard time finding trustworthy info on the internet, but seeing what you did actually works, I'd love to do the swap the right way on my truck as well, please!! Thank you!

@@udumkopf8217 I do not have the truck in front of me but I will check on that I’m still pretty sure it has a switch on it. The dryer didn’t come with a switch I do remember having to reuse the old one
hey dude, where did you bought your parts.I'm having a hard time to get this refrigerant hose and a/c receiver drier for those parts # for my 1993 gmc K2500
We thought this also but we went to the junkyard to see some factory ones and they all look the same so we just left it. Thanks for watching and commenting.

I have a 92 k1500 and my uncle has a 93 k1500, all he did was change the oil to pag and the adapters for 134a, he has cold air with the old system, I'm fixing to do the same.

What year truck did you did this on ?

You also forgot to replace the expansion orifice that's located inside one of the evaporator tubes

Sounds awesome! If it fits it ships brother man!
I would like parts list/ numbers if you still have them as I’m doing same thing to a 88’

I noticed that the outlet line from the dryer/accumulators doesn't have a switch. When you change it over do you eliminate the switch
@@udumkopf8217 I do not have the truck in front of me but I will check on that I’m still pretty sure it has a switch on it. The dryer didn’t come with a switch I do remember having to reuse the old one
Could I get the parts list and numbers for the R134 upgrade, I have a '89 C1500 with the 5.7. Thank you
They are all on a post that someone already asked on! Thanks for watching
I know the video is old but do you happen to have the part numbers for all the parts?
@@dyllongarner7409 I don’t anymore I’m sorry but everything for the conversion I got through rock auto
I heard you could reuse the condenser? True or false
True but at the cost of a new one no need to take a chance
hey dude, where did you bought your parts.I'm having a hard time to get this refrigerant hose and a/c receiver drier for those parts # for my 1993 gmc K2500
Rock auto
If you need anything else just leave a comment
Didn't you miss the orifice tube?
It was pre installed but they make specific ones so if you are doing this conversion you’ll need a r-134A one
Is condenser upside down?
We thought this also but we went to the junkyard to see some factory ones and they all look the same so we just left it. Thanks for watching and commenting.
Yes it is upside down
How much oil did you have to put in to the total system ?
6-8 ounces I have 6 in it but the internet has a lot of different people saying different things.
Would this info be comparable to an 88 Caprice?
Most likely not. Thanks for watching man!
They're banning 134a, so you'll be doing this again with some other refrigerant soon.
@@craig7350 ill do another conversion video when it happens 🤷♂️thanks for stopping by!
I’m looking to do this on my 93 K2500. So you have part numbers?

@@Levisbackyardperformance thanks !
So what happens if you just put R134a in an R12 system without changing anything?
Same thing i wanna kno too
Same thing i wanna kno too
Ever figured it out

Heater core??
Evap core
Lol I was just like brain dead
Evaporator is inside, condenser is outside. I always have to stop and think or I'll get the two mixed up.
