I have an AUII November 2001 build and there was a recall to drill the hole in the thermostat for them as well. I purchased a thermostat from ford and no hole, drilled it myself. Generally speaking, if you run 50% anti freeze anti boil in conditions that don't require it you may find your engine (inline 6) will run unnecessarily hotter.
