where is the drain plug for the radiator on a 1992 buick regal custom
You can find the 1991 Buick Skylark radiator drain plug on the bottom of the radiator. The radiator drain plug will be in the center of the radiator bottom.
If you can't find drain plug, just disconnect lower radiator hose.
There is none. You will need to remove the lower hose.
Bottom of the oil pan.
It seems these 2007-2013 GM lambar do not have drain plug.
Look at the bottom or rear of the radiator
on the bottom of the engine's oil pan
The drain plug is on the bottom of the oil pan on the bottom of the engine.
There is no drain plug for air conditioning. All is done through the service ports with a recovery / charging station machine. Some gm compressors have a crank case plug, but that is not a drain plug; it is to add oil when servicing the compressor.
