ac recharge procedure???

[rnj]

I was wondering what I need to do to recharge the ac on my 1997 olds 88. Not sure if it has r134, or r12. Or does that matter???

You have r134, the system should be leak tested first, then evacuated , the system is drawn down and checked to see if it holds vacuum for 30 minutes, if all is ok then it is recharged, usually this is not a dyer type job if done properly. You could buy a Walmart recharge kit, but you can easily overfill they system doing this, and there is no leak test performed.
