Review on Auto Meter 6937 Cobalt Digital Water Temp Gauge, 2 1/16 Inch by Andrew Webster

If you own a Ford pickup, you probably know that the factory temperature sensor is practically useless. This gauge does exactly what I need - shows exactly how hot my engine coolant is - and is pretty easy to install. I especially like how the numbers get darker and the "WATER temp" label lights up when the headlights turn on. Nice gesture. The Autometer is also right that the numbers don't change too quickly, which doesn't bother you while driving.
