How do you Clean the Radiator?
I just got done cleaning the Radiator. I use Simple Green and try to soak it as best as I can from the Engine Side. After a few hours I take a garden hose and spray it from the outside in.
i have tried a variety of things. from mineral spirits to simple green.
now i just use simple green the same way you do. it is much less nasty to use.
i also use my pressure washer if i feel like dragging it out

Steve and Tom, I use Simple Green's heavy duty solution (it is actually kind of purple in color) at 50/50, let it soak for a few hours and then spray off from outside to inside just like Steve. This last time I was able to use my friend's commercial pressure washer with a heater to really clean off the inside fins, and get all the gunk that seemed impervious to the Simple Green off completely. Engine is running about 6-7 degrees cooler now.
It does appear that Simple Green is corrosive to aluminum! We had better go to their Aircraft one or choose another detergent!
