Last year I replaced my radiator.
I had it checked since then, and was told that a pressure test showed no leaks or anything.
I check my coolant, both in the reservoir and in the radiator, and they are both full.
But I noticed (and this happened last year) that driving around town doing errands and there are lots of traffic lights, the temp gauge shows the line at halfway between cold and hot.
It hasn't done that in a while, but then, it has been cold/winter.
Today it is warmer, say 45-50 degrees out. And it did it today.
Is this a problem? Or is this normal?
Given there doesn't seem to be a leak, what would make the engine run so hot? Shouldn't it be at worst, maybe a quarter or a third of the way (the line on the gauge, I mean)?
There wasn't even really traffic, just stopping at lights and stuff.
Thoughts?
