2008 GT500 refrigerant capacity?

[Smokinstang65]

so, realized that the sticker on the radiator cover has fallen off on my hotrod and now i have no clue how many pounds of refrigerant it is supposed to have. Anyone out there have a picture of the sticker or knowledge of the info? Also, anyone know where i could get a new sticker for the car?

You really ought to go by the gauges when recharging rather than the sticker.

I've got an issue with the high side surging. Idling it surges up to 300 and then the fan kicks on and brings the pressure back down to 125. Fan kicks off, and it surges back up again. Obviously not an issue while driving as it'll maintain but at idle it's causing some issues with not putting out cold air. Was gonna evacuation the system and refill using the machine we have on base however no clue if what is in the system that gets recovered is the correct amount or not.

While the fans are cycling, so is the a/c clutch. When the compressor is not cycling, that's where you're seeing your spikes.
