ENGINE COOLANT TEMPERATURE GAUGE1. The magnetic engine coolant temperature gauge consists of three primary coils, one of which is wound at a 90-degree angle to the other two. The coils form a magnetic field which varies in direction according to the variable resistance of the Engine Coolant Temperature (ECT) sensor, which is connected between two of them.
CAUTION: Do not remove pointers; they cannot be recalibrated.
2. A primary magnet, to which a shaft and pointer are attached, rotates to align to this primary field, resulting in pointer position. The bobbin/coil assembly is pressed into a metal housing which has two holes for dial mounting.
3. There is no adjustment, calibration, or maintenance required for engine coolant temperature gauge.
