For the longest time I wondered if my temperature gauge was broken since I've never seen it go any higher than the half-way point. Well yesterday, for the first time in about 147K miles, it moved up a little higher than the 3/4 mark trying to keep 65mph going up some hills on Route 80 in New Jersey with gobs of other traffic in 100+ temps. I think I'll check the coolant level, just to make sure it's not just low.
