I have some stuff i used in my car it I loved it I want to do it to my friends 2.4 but the guage says their cars already completely full just a hair above full I know how to add it but before i do i gotta figure out how to get the pressure or r134 out I don't see it explained in the haynes manual either just how to add?
technically only illegal if youre epa certified. if youre not, the govt assumes you dont know its bad for the environment. but if you are, you can get like $20k in fines and up to like 10 yrs in prison. at least thats what it was couple yrs ago when i got certified.
