New temp gauge hookup

Hey guys I'm installing a new temp gauge as well as oil pressure and volt and was wondering if anyone had an idea what size thread is on the fitting where the temp gauge hooks up on the water pump

What engine do you have? The temp gauge sensor is on top of the rear block, right behind the rear end of the valve cover, drivers side. That's the sending unit sensor for the gauge, the one inline of the water pump is the input for the computer. This is for the 2.5L though, not sure about the 6-cylinders.

You can take the sensor off, (recommend look at a new one at the auto-store), and then you'll confirm the thread size, they could vary per engine/year.
