Something sounds wrong with your engine overheating situation. You say the
block has been flushed twice?
A couple years ago when I had my block flushed, I checked the water jackets
before doing any rebuilding. I was shocked to find pieces of metal casting
inside the jackets. Some of these pieces were several inches long. I fished
them out thru the freeze plug holes. You can imagine that metal debris like
this can impede the flow of coolant in the engine, and that other gunk can
build up behind it creating a blockage. (After assembly, the engine never
This was no fault of the block tank flushing. It was a by-product of the
manufacturing process. A long time ago another 2000 engine block of mine had
a constricted passage, and I opened it up by breaking off the metal casting
that constricted the flow of coolant from the block into the cylinder head.
The engine ran cooler after that.
Not saying that this is the situation with yours, just a possibility to
