Overheating -- Corrective measure questions.

I don't know if this is even posable but back in the day when SB Ford's went from v belts to serp belts they did not change how the water pump bolted to the front of the engine they just changed the direction the impeller should rotate and the internal pathways for the coolant to travel.

Everything else would just bolt up, fan, pulley etc

If one bought a serp pump and put it on a v belt engine the pump would be run backwards. That would cause all kinds of issues
