Well now I’m totally stumped. Shop called, it is still overheating and did it on them as well. But all the tests came back good, it’s holding 17.8 PSI, it’s flowing. It’s not got any gasses or foreign material in the coolant, his compression tests and leak down tests numbers were identical to mine. Fan relay and fans operating per specs. Radiator is flowing air across all 9 check points .
