I was trying to find the radiator drain plug. I do not see it. Am I suppose to remove the cover under the bumper? I'm trying to do a flush and replace my faulty thermostat in the meantime. Have anyone done it?

Never mind, I found the answer. I got my car on jack stand. Looked under and there is a two piece noise encapsulation I had to remove the bolts. I see a red plastic screw plug that's directly the botttom right side of the radiator. Unscrewed it and the coolant was coming out of the spout. It was coming out clear like water. When i looked in the bucket, it was brownish color. What color is the MB coolant suppose to be? I haven't put the fresh coolant since I am doing a deep clean flush and while I am at it, I have to replace the thermostat which should be an easy task.
