uhh hope this is in the right section, anyways going to get the engine running tomorrow and i dont know how much to put in the A/C system, like what all do i need cause ive never done a recharge on my neon. keep in mind im still running my stock lines not srt-4 lines. well LMK as its hot hott this week and i wanna get it charged if everything else turns out fine tomorrow.

If you care about your A/C system, it's always best to take it to a place that does A/C work and let them do it. I've used the recharge cans before, but it's always been on old vehicles that I don't really care about. A/C systems are pretty delicate....and even though you might get cold air for a couple weeks recharging it yourself, you almost always hurt it for the long run. The whole thing needs to be pumped down, so there is NO air inside the lines. That's the part you can't do yourself....that really needs done for the health of all the components.

This.

the system to needs to be pumped down to a positive vacuum before a recharge. This is needed to, remove air and water from the system. It is also adviseable to to replace the receiver/dryer if the system has been open to the air for an extended time. The system can also be checked for leaks as it is requires to hold vaccuum for a specified time.

Positive vacuum is kind of a conflicting term.

A near* total vacuum may be a better way to put it.

The vacuum for a few hours is to evaporate all the moisture from the system. If you had it apart, this is a must. The moisture (humid air) in the system, and what the accumulator/drier may have absorbed, will corrode the internals of the system.




*A perfect vacuum is not possible while in the earth's atmosphere.

Thank you Bill, you are correct. Dang these brain farts! LOL

Dayum. Okay guys. I just don't like taking my car to shops. The only tme its in a shop is like once a year & that's when I go to the performance shop where they do my alignment.

I'm with you there, but sometimes you have to bite it, and pray for the best.
