The alarm sounded, giving him enough time to pull over and let the engine cool before any damage occurred. A quick check revealed a minor coolant leak he could fix on the spot. Without the gauge, he might have driven until the engine overheated, leading to a costly repair in the middle of nowhere.\u003c\/p\u003e\n\u003cp\u003eMicro Comparison\u003c\/p\u003e\u003cp\u003eMany single-function gauges only show one reading at a time, forcing you to install multiple units or switch between displays.
