Does anyone know the thread size/pitch for the STOCK coolant temperature sensor under the oil filter pedestal on a 1985 12a? For example these:

More Information for AIRTEX/WELLS 1T1122

I searched the forums and internet and came up with just about nothing. I know its metric.

 

There are two different sensors depending on if the engine has a reman iron or not. Reference here: https://www.mazdatrix.com/79-85Electrical-Engine.htm

Not sure of the thread pitch.

 

I think it is a 1/8 BSPT (British Standard Pipe Thread) which is close to 1/8 NPT but there is a little play when screwing it in. I think I still have my temp sensor in my old 12A at home and can check later tonight.

 

I'm pretty sure I found my answer after a few hours of Google searching and using actual Mazda part numbers.

I believe it's m8 x 0.75
