What pag oil does my car listed above take?
There is no Freon in the AC system. I pulled vacuum for half an hour after waited another half an hour no drops in vacuum. I checked shredder valves they are not leaking.

Good afternoon.

It takes pag 100.

As far as the no Freon, vacuum tests are not always accurate. You need to pressure up the system and look for leaks. Look at all the joints and connections for anything black or green.

I added some AC dye. I let it run for a while today. Tomorrow will check it with UV light.
