The original temperature gauge stopped working last summer, and he worried about overheating while towing a trailer up mountain roads. He installed this 2-in-1 LCD gauge in about an hour using basic tools. Now he can see both his battery voltage and coolant temperature on the same screen. On a recent trip, the flashing alarm caught his attention when the temperature climbed during a steep climb. He pulled over, let the engine cool, and avoided a potential breakdown.\u003c\/p\u003e\n\u003cp\u003eMicro Comparison\u003c\/p\u003e\u003cp\u003eMany analog gauges are hard to read at night and only show one measurement.
