This is my first year winterizing my 1997 400EC. I have 7.4L MPI's with closed cooling systems. I am wondering what precautions need to be taken to insure enough antifreeze (pink) is run through the raw water portion of the engine cooling system to insure protection of the water cooled manifolds and the exhaust mufflers. The exhaust mufflers look huge and it looks like that might take a lot of "pink". Can anyone help this first timer?
