[QUOTE="tJKrider, post: 463655, member: 25640"] Have you re-geared? If not, you're operating your engine in a low rpm/high load map running down the highway. Lower engine rpm also means lower water pump flow. This all equates to higher heat soak. 6th not helping makes since as it puts the engine into an even lower rpm. If all was fine before the t-stat swap then it may be a low quality stat that is not functioning quickly enough. Replace with OEM or equivalent and give that a try. You should also be sure all the air is burped from the coolant system... [/QUOTE]
