What Size Thread Is The Water Temp Sensor (Cluster Gauge)

[bobby_lat]

What size thread is the water temp sensor as i have just got a "Drift iridium series water temp gauge" (which comes with a new sensor) and was wondering if i can just change it out with the stock sensor without redrilling , tapping etc. Looked everywhere couldnt find the info.

I have a 93 model s1 r33 gtst.

You can't replace the factory sensor, the ECU uses it heavily for fuel correction.

I am guessing the sensor for your new guage is 1/8 NPT?

Seeing you don't want to drill / tap, you might be best getting something like this which you plumb inline with your radiator hose.

They are in different sizes so make sure the one you get is the right size for your radiator hose.

I thought the r33 had 2 water temp sensors one for the ECU and one for the gauge on the dash, and that u can just replace the on that goes to the dash?
