i do live in miami, and its not cold at all! i just got the ford focus 2001 diagram and am tracing all the components, relays, and connectors to the cooling system! when the engine gets hot, it turns on one fan or both to keep it under 225 F? or just one fan turns on? I am checking the diagram for engine cooling system for a zetec-e without air conditioning, meaning thats the one that cools down the engine, correct?
