I was at the pick n pull last month while visiting Albuquerque New Mexico. There was about 3 q45s in the lot (I must have went back and forth about 5 or 6 times getting all the parts I could think of I needed).

I noticed one had a heater core removed, and it was removed without removing the dashboard. I seen the evap box removed, but looks like it got a little damaged in the process. But atleast now I know where it is exactly, just behind and to the left of the evap box

If anyone out there knows, were you able to re-install the core without removing the dashboard and without breaking the evap box? I ask because my OE core is coming in, and considering I already took the dash out (only to put it back together), I am curious to know if I can get around it.

Never mind...figured it out. Mods can delete if want to

was there a coolant valve on the heater core/ or lines ?
