How much R12

[LewG]

I'm ready to charge my 86' El Camino's A/C system but the previous owner removed all the labels on the system. Does anyone know what the correct amount of R12 is? It was a v-6 originally but I think the v-8s hold the same amount.

My 1986 Pontiac manual calls for 3.25 lbs for the "G" model. No engine difference.

Yep, 3.25# for R4 compressor, 3.5# for A6 compressor in a G body

Thanks.
