bobby_lat Posted April 30, 2013 Share Posted April 30, 2013 (edited) 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.

paulR32gtr Posted April 30, 2013 Share Posted April 30, 2013 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. http://www.ebay.com.au/itm/Water-Temp-Gauge-Radiator-Hose-Sensor-Adaptor-36mm-BLUE-/160562099474#vi-content Link to comment https://www.sau.com.au/forums/topic/424443-what-size-thread-is-the-water-temp-sensor-cluster-gauge/#findComment-6833670 Share on other sites More sharing options...
bobby_lat Posted May 1, 2013 Author Share Posted May 1, 2013 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?
