Question about 1997 Oldsmobile Achieva
If thermostat was re-installed correctly then I'd say, remove rad cap, start engine, turn heat on & let coolant circulate for a while with cap off to remove air-locks in system. Rev the engine up slightly, once in a while to increase the flow through the system. I usually let the rad fan come on 2 or 3 times before I put cap back on, just to be sure all air is out of the system. Let me know if that does it.
