on a 1994 Buick le sabre, the temperature sensor is on driver's side of engine. remove the air box hose, the flexible one from the throttle body/mass air flow and put your head down there and you can see the temperature sesor underneath the throttle body. follow the two wires on the back of the motor on the manifold (maybe in a wire loom) and the two will run together under that point of the throttle body. remove the clip connector, it's a little tough if you have sausage links for fingers. after you remove the clip, a deep well metric socket should fit over it with some socket extensions on the socket and do it to it. i forget which size it was but you could just size it on your new one. good luck
Normally 180 On hot days it might go to 200
On a 1995 Buick LeSabre, the temperature gauge is located on the instrument cluster, which is situated on the dashboard behind the steering wheel. It typically appears as a dial or indicator, showing the engine coolant temperature. If you're looking for the actual temperature sensor, it is usually found near the engine, typically on the cylinder head or intake manifold.
