I had a van that did this, my radiator was going bad.

Radiator checked out fine. Have no clue to what it could be. Purged the line. Changed coolant resevoir cap.

Steven, have a combustion leak test done. if there are combustion gasses in your cooling system then you might have a bad head gasket. many shops can do this, or you can buy a kit from the auto parts store for about 50 bucks and do it yourself. lots of youtube videos on the net.

I agree, check for combustion gases in the cooling system. If you have a Northstar it's probably going to be the head gaskets. All Northstar engines blow head gaskets sooner or later!! HTH. - Jim

Can you just trust the Cadillac service mechanic to diagnose it?

On something this old, the Cadillac Dealer may not want to work on it. You can give them a try. I'd recommend a Cadillac Dealer if yours will work on it. If not, try your local Chevrolet Dealer. They tend to be a lot less snooty. HTH. -Jim
