Thread pitch/size help!
Pappy, or whoever might be able help. I have and 85 4runner, with the same extra port that Pappy moved his factory water temp sensor to. I removed the plug, but cannot for the life of me figure out what the tread is on the sensor. I combed the forums, and there was a lot of speculation that it was a 3/8 BSPT, so I went through the trouble of getting a 3/8 BSPT to 1/8 NPT (the size of my aftermarket sensor) from 42draftdesign.com (the only place I could find one) only it does not fit. Pappy mentions a "metric conversion" but which one?? I cannot find this anywhere. Did you have to tap the upper port? and if so, what size did you tap it to?
Thanks much
