The 1990 Buick LeSabre oxygen sensor is located on the outside of the air cleaner housing. The oxygen sensor will be on the back side of the housing.

99 Grand Prix Coolant Sensor InfoThe coolant level sensor on this car in called a "coolant level indicator module" and is a small square box attached to the RH (pass.)side of the rad,engine side(rear)of the side tank,about 1/2 way down.The wiring plugs in from the bottom. It is held in by a snap clip and seals with an o-ring.Submitted by Andrew at Zippy's Auto in Edmonton Alberta Canada
Its the bleeder screw, its used to let air pockets out the coolant system.
Is the question how to bleed a Buick 3800 cooling system? I would say open that little petcock by the themostat housing and release all the air as you fill the system with coolant. When coolant comes out instead of air all the air is out.
look under the throttle body on the front of the engine there s a sensor with 3 wires going to it that is the engine coolant temperature sensor
Should be a plastic key shaped thing. bottom of tank, corner, engine side.
Alot of buick regals and lesabre's came with the 3800 engine
