Recharged the AC in my 08 RL with 395k KM

Have had my RL about a month and it has approx 395k km. AC blowing hot air.

I watched a bunch of videos and was almost scarred off by Scotty Kilmer (I'm a big fan for years) but decided to take the risk.

Drained one bottle (425g) with the engine running, AC on blast with the can connected to the low pressure, service port. AC is blowing cold now.

The guy at the parts counter sold me two cans and the connector. I decided to not add any more than the one can because I can't really tell how much is actually in the system and if I'm not mistaken, Scotty said that most AC units in cars hold 450g. I didn't want to risk anything else. I did notice that one of the fans (AC compressor fan?) kicked on about a minute or so into the procedure.

When I unhooked the connector, a little bit of green (refrigerant?) pop-fizzed out of the port kind of like cracking a fresh soda, which I quickly wiped away. (I was wearing my safety sunglasses).

So far so good but I was just curious, does anyone have any experience with this and offer me any tips, advice or what to expect in the future?

Thank you kindly!

Who knows what was put in there…
the green may be pag oil uv dye, stopleak…etc… who knows..
you more than likely have a leak.
you can rent gauges From parts stores..that is best to know what pressures are..
cannot see what you put in if its pure 134 or does it say with oil, stop leaks etc …
you should only add freon unless you know.what it needs..use gauges get pressures right and see what happens.
.or vacuum use dry compressed air and check for leaks.
or pull vacuum, flush system ( not compressor just drain and flush with correct oil) add by weight and gauges refrigerant and oil amount prior.
I can see the can now r12A ?.??? You should add 134..
again try it and see what was done already anddrve it..but if goes out again i would fix leak flush reset..while you still have good compressor.
Think 12a is basically propane and flammable
