You shouldn't mix different kinds of antifreeze. They have different chemicals that may cause other problems when they're mixed together. Your tester with the little balls is probably calibrated for ethylene glycol antifreeze, and when you mix the two types together the tester won't give you accurate results! Does the tester say on it what type of antifreeze it's made for? What chemicals are in the green and the orange antifreezes? Ethylene glycol or propylene glycol?

The water will flow the same direction thru the engine whether the belts are the standard "V" belts, or the serpentine belt. The internal design of the waterpump will be different because of the reverse rotation of the impeller, but the water will still flow the same direction.
