can you say radiator??? After exhausting all avenues. It was a recoring of mine. New stat, water wetter, sealing up the front end to push all air coming through the grill into the radiator, new fan. The core was pretty corroded up. I had (4 rows) 3/8" tubes
they installed (4 rows) 5/8" tubes. problem solved.
