Question about 1989 Cadillac Seville
I had the same issue and I flushed and drained my old coolant and added a premix 50/50 coolant that does not require you to mix, just add. I replaced my thermostat with a new one and most important I replaced my water pump and put a new gasket. once that was complete it ran fine. also I noticed that if I raised the temperature on my heater above 72 degress, the car starts to overheat. might want to check and see if yours does the same???
good luck and hope this helps.

I feel for ya' , been there done that. The problem seems to be the head gaskets which fatigue from
the head bolts stretching, causing combustion gases to enter the cooling system. The pressure buildup of hot exhaust gas boils out the coolant causing an overheat condition. The "ONLY" solution
is a pressure bleed-off device used on hot water boilers, which is not a permanent fix, but you will get
quite a few thousand miles out of it. Second and final solution replace the head gaskets with the updated ones and be sure to include NEW HEAD BOLTS. Have Fun !!!!!!
