How do you feel about changing a water pump as preventive measure?

Rock Auto has Motorcraft Gold (= yellow). It had the lowest price I could find on that, so I bought the premix from them. That's what the later Rangers through 2011 took. In a pinch, you could always buy from Rock Auto if you can't find Motorcraft coolant locally. As part of a larger order, the shipping cost was very reasonable.

Dex-Cool = Motorcraft Orange, which replaced Gold in later applications.
