The ECT(engine coolant temp) sensor has been the same for almost 30 years!!
Almost all cars use this sensor until the late 90's, even the same color wire- GREEN.
The values are:
110ohm = 60C
67ohm = 80C
38ohm = 100C
BY these figures the gauge is incorrect!!
The sending unit is telling the gauge to read around 86C the way I figure it.
Possibly could add a 10 ohm resistor to the circuit.
