Question about 1993 Oldsmobile Cutlass Supreme
Already changed thermostat but still blows cold air
If the heater hoses are getting hot, and the radiator is full of coolant, it could be a faulty blend door under the dash.

after replacing the thermostat and when you refilled th radiator did you make sure you got all the air out of the cooling system? if so my guess would be you got a head gasket problem.In the long run take it to a shop ,have them check it out and giveyou a estimate.

as long as the engine temperature is normal, i would suspect a clogged heater core, the dex-cool antifreeze is notorious for building up deposits in cooling system. have heater core flushed first to see if it makes any difference

See my posted question under 2001 Mercury Villager: "HEAT BLOWS COLD WHEN CAR IS IDLING" I got an answer from chuck943 about air pockets and it was very helpful.
