[AJD] Rust scales in block - Help???

[Karl Olmstead]

I've had fairly good success directing the high pressure spray from a
pressure washer into engine coolant openings, Dean.  The impact of the water
breaks up a good share of the rust and scale.  Make sure you have all other
coolant connections open so that the water and rust has some place to go.
Even a flush with a garden hose is better than nothing.  Don't do use the
pressure washer on the radiator!
