filling A/C from empty

I need to recharge my A/C system after an O ring crapped out. How much r-134a do I need and is there anything special I need to do when filing it up?

Several cans. But - you NEED to pull a vacuum on that system before you charge it. Leaving even that small amount of atmosphere air in there can creat too high of a head pressure and prematurely wear out the system. You will want gauges and add enough refridgerant to get about a 35 -38 degree coil (low pressure side, blue gauge).

Do it right - or you will do it over, and next time be replacing the compressor and maybe more....

Thanks. I kinda figured there would be something special I would have to do other that hook up a can. After a little more research I see what you're talking about.

It's also recommended that the orifice tube and accumulator be replaced when the system has been opened to the atmosphere
