I bought the truck used in July with 97k miles on it.
It's at 111k miles now.
I haven't performed any coolant maintenance to it yet, and to my knowledge the EGR hasn't been cleaned.
I let the truck sit overnight, and it was lowish again in the morning when I fired up the truck.
I ended up adding another 3qts to the overflow tank, and it has been running normal temps ever since.
Ran all over creation yesterday with it, never got anywhere above 205*, and the coolant level has stayed the same.
I am off work until the 30th due to vacation and auto industry shutting down during the holidays.
I will check it again in a few when I want to start running errands.
