My 00 LS V-6 has just started to run hotter than normal when at highway speeds (60+ mph). It goes to midpoint between normal and hot. Then when I come to a stop it cools down to normal. no coolant leakage, cooling fan does come on. Replaced a funky looking degas bottle cap with a Motorcraft one today. Will test it tomorrow. Anyone else experience this condition? Possible causes/solutions?
