Is It Normal For The Digital Temp Readout On A 97 Deville To Move Up And Down From 197F To 212F? It Will Move All Around And Like To Stay On 208F Or 212F.I Just Tried To Change My Coolant And Did Not Successfully Drain But About A Gallon Of My Coolant Then Added A New Gallon Of DEX - Cool And Six GM Tabís!

My '97 Deville rarely moved much. It ran 206 in the summer and 213 in the winter.

You should have gotten more coolant than that out of it. Did you pull the lower hose?
