I think I will likely change the tstat, and do the coolant flush/change out at the same time. I figure it certainly won't hurt, can only help. Since getting the Scangauge, I don't remember seeing over about 182, so I have my doubts that it is working correctly. When I reviewed the Scangauge, it gives a max *F for ECT, and it read 186, never saw that so it must have only blipped by.
Thanks for the input, guys.
Just read another post pointing out the high frequency of failed oil coolers after the coolant flush and change. Should I just change the oil cooler, too or hope it doesn't happen to me? Sounds like the flush is what brings about an early demise of the oil cooler. Is Restore the Grim Reaper of oil coolers?
