Hi, today while installing a couple things I accidentally loosen this bolt attaching to this pipe that label "H" and as soon as the bolt was loosen air compress was shooting out and I immediately close the bolt. I want to know what is this bolt and pipe? And what is the air shooting out after I loosen it? Did I damage anything? Thanks for your help.

Engine is stock ka24de, bolt and pipe is right next to intake.

That's your high pressure refrigerant line for your AC system. I'd put a little more R134a in from a can. Won't need much, but probably good to make sure it's charged well (run it for a minute full blast, get a can with one of those dummy gauges - connect it to the LOW pressure side, the other cap with an L on it, probably by the AC compressor).

But your car is fine as long as you closed it back up quickly and put a little more refrigerant in.
