where is the drain plug for the radiator on a 1992 buick regal custom
Drain plug is located right on top the right side of the engine where the radiator hose connects to the manifold. That is also where the thermostat is located.
It's on the Driver's side near where the headlight is.
It is the 13mm bolt on the front of the oil pan, just below the oil filter.
If the radiator is original, LEAVE DRAIN PETCOCK ALONE !! You may NOT be be able to close it completely due to rust. Disconnect lower radiator hose instead.
