Just put a new compressor on mine and I think it took 6-7 cans for get it full and I have rear air too.

Thats the incorrect way to do it also, u may get the compressor to come and and blow SOME cool air but it will never be as cold as its suppose to be and ull cause ur compressor to go bad prematurly.
