I use Simple Green Pro HD. It's non-corrosive and can be used on aluminum items like the radiator , CAC,etc. I clean the engine/tranny once a year, a week or 2 prior to doing the annual chassis service. That way I have a clean work area and if there are any leaks, I'll see them.

Same here except I use the degreaser at the car wash.
