This happened to me. I used to be at dead 80 most of the time, a little higher for a bit after coming off a highway. Changed water pump, hoses, belts (belts tightened exactly with a Krickit); was green antifreeze now correct mix of MB antifreeze. Now I see 85-87. I'm quite certain that I don't have an air pocket.

Two things:

1. I don't know the tolerances that thermostats are built to; my first one was a Behr, this one is a Wahler (sp?). My readings would fall into 5-10% tolerance. And who knows if the dash gauge is exact in the first place?

2. I also got a new pressure cap for the overflow tank. It was very tight, and in the process of changing it the neck weakened and now bubbles and leaks (new one arrives Tuesday). This amounts to a pressure leak (not a lot, but it is something), and this will cause temps to go up. I'm not driving on any significant trip until this is replaced, and I'm watching temps like a hawk.
