Thread: Need some A/C advice

Got all the parts to re-install my A/C system. What I'm wondering is; do I need to pull vacuum on the system before charging? I know some people do it this way, but I've heard some people just start filling. I know one of the reasons for pulling vacuum is to check for leaks. I can get a set of gauges, no problem. Finding a vacuum pump is a different story though.

Any answers or advice guys?

A/C what??? our cars have that stuff. lol



yes from what i understand vacuming the system if in not mistaken will prevent moisture from entering the system apon fill... but i could be wrong. either way vac the system 1st.

Definitely pull the vacuum. It removes the air from the system. Air contains moisture which can freeze in the evaporator and block the flow, or worse.

Thanks guys. That's all I needed to know. Now I just need to find a vacuum pump. :/
