The above info, came from the AZ site, they try to cover a bunch of years with their info. Can you locate your cabin filter? Some of my info shows it under the center of the dash.

I'd probably check vacuum source at the valve, first. If you take anything loose, it looks like coolant may try to run everywhere.
