What is this sensor?

This is on the passenger side on the bottom of the block, above the oil pan. The wire coming out of it burned in half on the header and I can't find the other end.

It appears to be a temperature gauge sending unit. What engine do you have make model and year.

there is a few threaded plugs into the block cooling jacket on that side and looks like a PO put in a temp sensor there but a bad spot as the majority of Engine Heat is in the Head , a sensor there would not be accurate for running temp.

Unscrew it out of the block if it is in the water jacket it will allow coolant to escape. It does appear to be a capillary style temp gauge (mechanical as opposed to electric).

Yes, the TBI coolant sensor uses the front right coolant port on the intake manifold. If your CJ is running a mechanical coolant gauge then the block drain plug port would be where it was moved to. If your CJ has the electrical gauge hooked up it uses the small coolant port on the front left of the the intake. Do you have the stock intake manifold or an Edelbrock?

Stock manifold I guess. And it's the stock temp gauge in the speedo cluster.... Which always reads the same.
