CHANGING A CHARGE valve core. After vac/down, how much freon is to be put back?

 

There should be a sticker under your hood that has the oz of R134a.

17.6 to 19.4 oz is the spec in the shop manual.

 

Thanks for the simple answer without a lot of criticism

 

No worries. I am sure there is a regulation requiring car manufacturers to put the amount of R134a in the system somewhere on the vehicle. Put that information for others who may need to quickly find out how much r-134a required for their car.

I have an electronic copy of your shop manual, so I could look it up.
