The last check on the coolant system is to pressure-test for leaks, and the cap vent pressure (6psi = FAIL). The overnight pressure test revealed that the upper radiator hose top clamp was slightly loose, and there's a tiny leak in the timing cover gasket - probably not worth fixing right now, if the coolant is changed & maintained on-schedule (every 3 years regardless of miles).

Pressure-test coolant system $20 DONE
R&R coolant $50 (includes concentrate & distilled water)
MotorCraft RS62 radiator cap ~$15 locally
