As trucks get more sophisticated, the monitoring of these complex machines becomes more important. It is our belief that within the next decade, dash gauges will be replaced with microcontroller displays which can evaluate the conditions and provide both visual and audible alarm when conditions warrant. For now, though, you had better understand all these gauges.
We aren’t going to treat you like a fool and explain what the speedometer, temperature gauge, and oil gauges do. But we will explain what range most readings should be within, and we will explain those gauges which aren’t normally found on cars.
The following gauge readings and purposes are typical. For your truck, consult the manufacturer’s manual for exact parameters:
