I run the eninge for a few min to get it a little warm. Then with the hose wide open I just soak it down. Then spray down with simple green. After being sparyed down I take a soft brush and just go over the enigne. Let it sit for how ever long it states on the simple green bottle (i can not remember). Then just hose down the engine bay and wipe down the heavy water. Then just start up the engine and let it try the rest of the way.

It is nice and simple and I do it about once a month now.
