I usually like OEM thermostats. My Explorer never runs at the right temperature. Never hot, but 1/4-1/2 zone. Moves around, and the dash gauge is accurate. ECT says low 170s to mid 180s, so it follows the scan tool. In essence I'm running a 180 stat. Many cooling parts were changed over the years, the green coolant is on a 3 year change interval. 4.0 OHV engines have weird cooling, there is no bypass. Running cooler is good and bad, less wear and tear on the engine but probably more fuel used.
It will never enter the thermometer icon, which is 190-200. Ford stat is supposed to be a 192. Seems the 4.0 had a few temperatures in the 190 range and it was consolidated to one part number.
I'm thinking of trying a superstat, 195F. Says it uses a design that keeps a constant temperature. The Ford stat has a bleed hole. Superstat has the v notch.
It its cheap, under $10 for the stat and gasket, but still it has to be drained and burped.
Any good feedback on Stant stats?
