On all 3.8 engines that I have worked on, the thermostat was under the metal fitting where the top radiator hose connects to the engine.
Good luck, be carefuland don't get burned.

Not very easily if at all, and why would you want to?
The thermostat on a 1991 Buick Skylark is located near the engine. To find the thermostat, follow the top radiator hose directly to the thermostat.
right where the coolant hose enters the engine block
The hose that goes in the top of the engine, the thermostat is in the hose.Unscrew the hose take the thermostat out and replace,Very easy
Follow the top radiator hose back to the engine. The thermostat is behind the housing that connects the top hose to the engine block.
The thermostat is usually located in the housing where the upper rad hose is clamped to the engine.
below the inlet hose on the engine block
depends on the engine size

Where is the thermostat located on a 1987 Buick LeSabre?
where is the thermostat located on 95 buick regal
It's on the drivers side of the engine, right near the air cleaner. There's a hose going into the pipe that has to be removed on the upper part of the engine. The thermostat is in there.
