Okay, have a 2000 deville base. It's overheating. No leaks, not losing any

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
