Thanks for the suggestions. I have the van up on stands and have been all around underneath with a blacklight. No dye except where some oil came out of the evap core when I was putting it back in. And nothing on the ground. That said, I can't see the underside of the radiator or condenser ... sounds like maybe I should bite the bullet and take off the grill, etc. to get at the condenser?

Also, on your suggestion to put some charge in it and listen for the leak. How much will I need to expect to see dye and or narrow it down by siound? And I have to run the compressor to charge it right? So I'll need to at a minimum put the coolant overflow and battery back in? Is there a way I can accomplish the same thing under vacuum? It's free and I don't have to run the van.

Wondering if I should invest in the $60 HF leak detector ...
