There is no drain plug. You have to use the radiator hose as your drain. Disconnect it from the bottom.
Just below the lower radiator hose is the drain plug. Be careful and do not use force as it is plastic. jd
Many vehicles no longer use a radiator drain plug, since so many of them are corroded shut by the time you need to use them. But if your vehicle DOES have a radiator drain plug it will be somewhere on the bottom, usually facing the engine side of the radiator. BTW, if you can't find a working radiator drain plug, just remove the bottom radiator hose. Apparently who ever wrote this answer didn't read the question. The question is about a AC drain plug not a radiator drain plug. I am looking for the same thing so please can someone correct this answer.
I'm not sure about this particular car but not all radiators have a drain plug. If you cannot locate the drain plug then simply remove the bottom radiator hose to drain the radiator. Keep in mind that you may need to replace the hose clamp if it has the one-use factory style clamp. The drain plug is directly below your upper radiator hose at the bottom of the radiator.
The radiator drain plug is on passenger side of the radiator tank at the bottom. You can use pliers to loosen it. Be careful that it does NOT come out, only loosen it enough to drain the anti freeze.
Under the radiator just use some pliers
The drain plug is on the bottom of the radiator on the drivers side. It is small white plug, and can easily break, so use care when removing.
The Oil Drain Plus is on the back of the oil pan. If you lift the car, look underneath, just behind the front passenger (assuming Left-Hand drive!) wheel. You'll see the oil pan and the drain plug. If you're looking for the Radiator Drain Plug, lift the car, and look just underneath behind the bumper. There is an oval hole about 2" long on the large plastic splash pan. You can use a Phillips head screwdriver to remove the radiator plug.
front splash shield has to come off! then you can see the drain on the right bottom of radiator looking at it from front of car. you can use a Allen wrench to loosen the drain plug.
I had to use an oil sucker that sucks the engine oil out from the dipstick hole. I could not locate the drain plug under this car.
For a 1998 with 4.0L V8, it's located on the driver's side of the radiator. There is a hole about 1- 1/2" in diameter through which you can use a 19mm socket and extension to turn the plug CCW to open.
The drain plug on the radiator of a 2002 Cavalier is located on the front of care through the lower front air dam area. You will find it's on the right and you should use 1/4" ratchet and extension to open it.
