FWIW: If you happen to see see another "orange colored leak" on your garage floor you may have the same thing I experienced.

It appears that after an extensive pressure test they found that the upper hose clamp on the upper hose crossover was loose.

This left a dinner plate size of orage stuff on the floor near the left front fender.

I had already done the radiator thing so it was a surprise.

All is good now.
