coolant temperature sensor
I have a 94 XJ 4.0HO. There's a temperature device on the top corner of the head (close to the driver side). Is this the coolant temperature sensor or a temperature switch? I looked for the part on autozone and they both have the same appearance. And if this a sensor, is this the sensor for the temperature indicator on the dash? Mine reads 0 most of the time. I'm sure I damaged that sensor/switch when I reassembled my engine and that's also the same time the indicator stopped working.
