URabbit, do you know what your coolant temp is cruising on the highway? I donít care what the gauge looks like, Iím looking for a digital number from a scanner / code reader / scangauge, or if there is a digital readout in a driver information center.

If youíre running slightly cooler than you should, there wonít be many symptoms. You would have reduced heater performance and fuel economy, but either of these could be minor enough a lot of people wouldnít notice
