What is the normal water temperature for a BMW 750?
1 Answers
Not only for BMW models, but for any fuel-powered vehicle, the normal water temperature should be 90 degrees. Introduction to the Automotive Water Temperature Sensor: The interior of the automotive water temperature sensor contains the water temperature sensor itself. The lower the temperature, the higher the resistance; conversely, the resistance decreases. It is installed in the water jacket of the engine block or cylinder head, in direct contact with the coolant, thereby measuring the temperature of the engine coolant. Principle of the Automotive Water Temperature Sensor: The electronic control unit measures the temperature of the engine coolant based on this change—the lower the temperature, the higher the resistance, and vice versa. The electronic control unit uses this variation to determine the engine coolant temperature, serving as a correction signal for fuel injection and ignition timing.
