- This is not a how to vid. Im just showing you where im at with the truck. Even tho im going to swap out the engine later on, I still want to clean up the old 20r for the future owner.
I had a 1980 Toyota Pickup for a couple years (2015-2018). The ac system was an original R12 unit. It was not working when I got it (no refrigerant in the system). The few things I did was replacing the o-rings on the fittings that had them, buy the R134 adapters and installed it on the ac compressor, and I also replaced the drier. I rented an ac gauge and a vacuum pump from AutoZone. I used that to pull a vacuum on the system to see if there were any leaks. Everything checked out fine. I kept in mind that this ac system may have residual R12, so I ended up buying the small can of R134 ester oil charge. I used the whole can and then I filled the rest of the system with R134 until the pressure in the system was in range. It ran cold for a couple years until one of the metal lines on the condenser decided to crack.
Same. Previous owner swapped the fittings to the r134 , the fittings were leaking everything else seemed to be ok. I know he didn’t do it the right way which I still need to do that lol,
@@luckycarguy Yeah, I found the r134 adapters would do that. I ended up going to Home Depot and bought the yellow teflon tape meant for gas fittings and wrapped those on the threads before putting on the adapters.
