Question about 1997 Oldsmobile Aurora
It appears we have an Air lock scenario and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
If persistent boil ups/over attention must made in the cylinder head
or gasket area, or possibly water pump?

Onyeredson has a great write up, no doubt.
But this is a lot of steps to take when considering that jmh didnt mention a leak or that he ever opened up the cooling system, thus how did the air lock get there?
I also would check the thermostat, besides if you never changed it on a 97 automobile, it time to anyway. they are only a couple of $. the thermostat is bolted onto the front of the motor, three bolts. it has a large aluminum knuckle looking thing with a flange and your three bolts. a large rubber hose is attached to the other end of the knuckle....hope this helps....if its not the thermostat, or blocked heatercore....reread onyeredson.
