Question about 1996 Cadillac Seville CA Value
Same problem with my 96 cadillac, don't be a fool like me, or anybodyelse and replace things such as RADIATOR, THERMOSTAT, WATER PUMP, HEATER CORE, HOSES, RADIATOR CAPS, RADIATOR FANS, And don't waste all of your money on coolant like i did. It is either Head Gasket, or Head Bolts pulled. I have replaced everything above and more, and still overheats, just as other people said and told me HEAD GASKET and i did not listen, now i wasted all of my money on stuff that did not need to be replaced. I'm sure you have a Northstar? Like me? One of the worst engines ever built in my book. Sell it quick if you do not have the money to fix it with, which is very costly. Or get a 4.9 which is more stable.

Sounds like it could be one of the head gaskets. does coolant belch out if you hit the gas pedel like if you were going to pass someone on the hiway. if it does, exhaust gases are presurizing the cooling system beyond the max. presure of the cap...

You didn't mention, but did you replace the thermostat? If not, please do. It's inexpensive and easy enough to do.
Hope this helps... Good luck!

The head bolts tend to pull out of the block, a GM design flaw. Engine replacement is the only solution.

Check your thermostat

Possible thermostat. Try removing it and see if your car runs cooler and stops overheating. If you don't know where it is, its easy. follow the top thick hose from radiator to where it meets engine. thats where it is. just undo hose at engine, (when cold of coarse) and just use a screw driver and lightly pry it out (very simple) and then just reattach hose. I think the car runs better this way, some mechanics disagree. only prob is in winter time your car engine won't heat up enough to allow heater to work. I live in Arizona so its not an issue for me.
