temperature gauge dropping slightly at highway speeds
ive noticed when driving at 60 mph that insted of temp gauge being in the middle, it will drop slightly. Any ideas of what it could be. Truck has 13,000 miles on it.

Sounds normal to me. Getting better air-better cooling.

Its normal, your forcing more cold air at the Radiator. As long as the gauge doesn't get to the extremes you are ok.
