I charged my A/C system and it leaked out over night. I put UV dye in the system and found it was the low pressure side Schrader valve. I put a new valve in so do I need to vacuum the system again or just put refrigerant in?

Yes,

I would vacuum it again, at least for thirty minutes.

Better to do it right the first time, or you might get to do it a second time.

Just here to give some help.

Let us know how cool you are riding around when you get it all done.

Soon as I get my new water pump on 'Willy' (below) I will be pretty cool once again also! (Wife has been in the hospital for three weeks with exhaust issues. Time has not been easy to find).

Did you bleed it down slow?

Did you lose much?

It leaked out over night the compressor would not kick in. Will I have to get the oil/dye injector or is there another way to add PAG46?

If there was not evidence of oil leakage, gas it back up.

The oil that you already installed is distributed throughout the system.
