I want to do it for my r33 GTST myself, but I don't know how to start my work....

Anyone can help me?

Need some equipment, when a place Re-gasses they generally empty the system, Vacuum Leak check it.

If it doesnt have any leaks, they top it up slowly, guy said it would take about 30 minutes to charge it up. They do it like that so they dont stress the pipes.

It's not something you can legally do yourself

if you turn on your a/c does a pipe frost in engine bay, if it does then you still have gas in system but low (mech will tell by gauge line). If pressure in system you don't need to dump or vac system workshops do this because there not really ref mechs so it's a fool proof way to get charge right (they charge to sys spec with charging cyl). If you know a frig mech who has 134a refrigerant & access fitting it will cost you much less. I live in Syd & am always doing my mates cars & not very often does any other part of sys leak other than seal. car sys hold very little refrigerant so doesn't take much to leak before sys no cool.

just for some info all car a/c sys leak due to belt drive & mechanical seal which is why as compressor gets older leaks more due to wear on seal with side loading (don't ever over tighten comp belt).
