216° is getting pretty warm. Make sure the radiator fans are working.

The correct thermostat temperature for your Buick is 195°F. This may be the beginning of a water pump failure or the intake manifold gaskets may be beginning to leak. If you're between 90,000 and 120,000 miles the intake manifold gaskets are definitely suspect! HTH. -Jim

I agree that 216° is a little too warm. A 195° t-stat and the engine probably wants to be at 200° or so. It is possible that you have some dirt or debris in front of the radiator and condenser or the radiator has some internal corrosion. In addition we have no way to determine the accuracy of the temperature readout. 216° likely won't hurt it though.

GM (and probably others) run the fans at 1/2 speed to keep the noise down. However as the temp creeps up, there is a preset (tempature) in the ECM that switches the fans to full speed. A GM Power train engineer told me they ran the 3800 for hours at 130 and the engine apprarantly loved it........the good news is you are watching your temp. As noted make certain the fans are working and the coolant is full.
