Where are the back freeze plugs located on a 1991 Buick Roadmaster?

On a 1991 Buick Roadmaster, the back freeze plugs are located on the rear side of the engine block, typically near the bell housing of the transmission. There are usually two freeze plugs positioned on the back of the engine, allowing coolant to circulate and prevent freezing. Accessing them may require removing components like the transmission or exhaust system for better visibility and reach.
