What is the normal range of the water temperature gauge during transportation?
2 Answers
During transportation, the reading of the water temperature gauge should be between 80°C and 95°C. The following is an introduction to the water temperature sensor: 1. Introduction: The internal part of the car water temperature sensor is the car water temperature sensor itself. The lower the temperature, the greater the resistance; conversely, the smaller the resistance. It is installed in the water jacket of the engine block or cylinder head, in direct contact with the coolant, to measure the temperature of the engine coolant. 2. Principle: The electronic control unit measures the engine coolant temperature based on this change. The lower the temperature, the greater the resistance; conversely, the smaller the resistance. 3. Structure: The car water temperature sensor is installed in the water jacket of the engine block or cylinder head, in direct contact with the coolant, to measure the temperature of the engine coolant.
Driving a truck for ten years, you gotta keep a close eye on the water temperature. The needle leaning left means it's too cold, around 90 degrees in the middle is just right, like our body temperature at 37 degrees. Once on a long haul, I forgot to check the coolant, and watched the needle climb to 105 degrees—scared me enough to pull into a service area right away. Turned out the thermostat was stuck. If that temperature had hit the red line at 120 degrees, the engine head gasket would've been toast. For long-distance hauling, it's best to keep it between 85 and 95 degrees. When carrying heavy loads, take a break every two hours. If white mist appears on the dashboard, it's already too late.
