Review on 🌡️ HOTSYSTEM Universal Water Temp Gauge: Electronic Blue Digital LED DC12V 2inches 52mm for Car Automotive (Fahrenheit) by Ron Thomas

I like this product because it gives me instant feedback on a specific temperature. I installed it on a 1929 Ford Model A and these cars can easily overheat on long drives. With this digital gauge I can see which way the temperature is going and I can instantly adjust my driving to check the temperature of the engine. With an old needle you will not notice the slightest change in temperature. If the arrow position shows a change, you actually need to change your driving style to avoid the problem. With this sensor, the passenger doesn't even notice that I've changed my driving style.
