You hear that guy's accent? You should avoid doing anything shady in that video if you can avoid it.

You really want that vacuum as far as possible, close to 30 in-hg, and it doesn't look like the engine vacuum pulls to that level. You not only need to evacuate all air out of the system, but you need any moisture that got in to boil off and that takes time and really low pressure. If you're in the US, the pumps aren't that much online and if you don't do it right you'll have to replace the compressor before long because the oil will turn to shit.

Good to know satan. My work used to have some vacuum pumps laying around but I'll do another check since I've not seen them around lately.

>>2991663
do you have an air compressor?

the moisture really is the problem because it gums up the oil which makes it coat everything inside the system
replacing the dryer goes a long way to help

all the cool kids use propane

>>2991751
I tried it once in a 134a system and wasn't too impressed by it's cooling abilities. May have had other shit wrong with that system at that time though too... Might have to try again someday.

Would intermittent hot and cold another car is having likely be the expansion valve? Also I know pic related is far from professional grade but will it get the job done?

I got the vacuum pump and the manifold gage for $66 on Alibaba. I'm not sure if those cheap leak detectors are worth it.

Also is you are on the US those can valves don't work great on the self sealing R134a cans. They work but not great and are only $3 on sale on Aliexpress.
