Does anyone know where it is? I'm doing all of my hoses and a few other PM items want to get all the old coolant out that I can. I read somewhere that the plug is under the turbo and EGR, just above the oil filters kind of in the middle of the block. I do see a bolt/plug there but am trying to figure out if it's the right one. Looks like a 17/19mm or so? TIA
