1994 Thermostat housing sensor
My 1997 NAS D-90 has an unused thermostat housing sensor. It looks like the sensor/sender was used at one point but that's neither here nor there. I'd like to use this location for another sensor and was wondering if anyone could confirm the thread size. It looks to be very close to 3/4" npt but I don't think it is. The threads are different it would appear and the diameter is slightly larger than 3/4" I have attached a picture of the removed sensor next to a 3/4" NPT bushing for comparison.
