I have a Greddy 52mm(I think it's the same one they still offer, it's about 5years old) water temp gauge, and I want to find out if anyone knows the size/thread pitch of the sensor?

I'm asking because I have it mounted in the upper rad hose, and wanted to change things up a bit and move it to the plug that is on the driver's side of the block where the A/C compressor bolts up. I just thought I would see if anyone knew of this particular sensor before I let all the coolant drain out only to find out I need to get an adapter!

Thanks..

 

Should be 1/8 NPT

 

Thanks.
Does anyone know the size/pitch of the plug on the front iron?
