Just got dash put back in and ready to charge up the ac. Do I need to add any pag oil, looked like some ran out of the old core? Thanks.

IIRC the evaporator holds 1 oz oil approximately.. Pretty sure I saw that on something that @IBMobile or @Mopar1973Man posted here. I do you should add some oil after the replacement. If it has been leaking a while maybe more. Those 2 are more versed in it than I am.

I would add just about 1 or 2 ozs of PAG 100 just for safety.

Thank you. The vacuum is holding so maybe the leak is fixed.

Can you get pag 100 mixed with a/c refrigerant in a 12oz can. That would make the oil easy to put in sense the vacuum is already pulled. I should have asked this question before I put it all back together. Thanks.

I found some on amazon. Maybe napa will have it. I will check tomorrow.

I know I you can buy a small can with 1 oz of pag oil with an oz or 2 of 134a and some of fancy 134a or stop leak. I have a can at home and just cant remember what the 3rd part is. Wal mart has them. So do other places but for double or triple the price. Not the biggest fan of WM but somethings I cant pass on.
