wagons Posted December 9, 2019 Share Posted December 9, 2019 Anybody know the thermo-switch size on the EA82 radiator? Getting a fan kit with a switch that taps into the radiator as I dont trust probes. the kit comes with a 1/8NPT switch as well as an adapter bung that goes to 3/8NPT. Are any of these sizes going to work? just want to make sure i dont blow money and order the wrong thing. Quote Link to comment Share on other sites More sharing options...
DaveT Posted December 9, 2019 Share Posted December 9, 2019 If it's a Subaru radiator, it is a straight thread and metric. Not a pipe thread. 1 Quote Link to comment Share on other sites More sharing options...
skishop69 Posted December 9, 2019 Share Posted December 9, 2019 Only way you're going to make it happen with an aftermarket switch in the radiator is to take an old switch, cut it down, drill it out and tap it to 1/8 NPT and that will only work if the inside of the old switch is solid. You could also find the right size metric bolt and do the same thing. That would be the way I would go. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted December 9, 2019 Share Posted December 9, 2019 And hose and fitting supplier could likely source an adapter to whatever metric thread it is. Or solder in a new brass bung and just leave the old switch to plug the hole. GD Quote Link to comment Share on other sites More sharing options...
naru2 Posted December 9, 2019 Share Posted December 9, 2019 You need something like this in a smaller size https://www.amazon.com/GlowShift-Female-Sensor-Adapter-Reducer/dp/B07D7FL72N Quote Link to comment Share on other sites More sharing options...
naru2 Posted December 9, 2019 Share Posted December 9, 2019 Pretty sure this is the correct one https://www.amazon.com/GlowShift-Female-Sensor-Adapter-Reducer/dp/B00NWZZBS6/ref=sr_1_1?keywords=m16+1%2F8npt+adapter&qid=1575914682&sr=8-1 Quote Link to comment Share on other sites More sharing options...
wagons Posted December 10, 2019 Author Share Posted December 10, 2019 @naru2 thanks. I talked with glowshift and that is indeed the right one. Ordered one yesterday and now I am just doing some finishing touches on the car. Quote Link to comment Share on other sites More sharing options...

FerGloyale Posted December 10, 2019 Share Posted December 10, 2019 Why not use a factory thermo switch? No adapter. Turns on fans at ~200 degrees. Use it to trigger a relay that powers the fans directly from battery (through fuse) Quote Link to comment Share on other sites More sharing options...
wagons Posted December 10, 2019 Author Share Posted December 10, 2019 @FerGloyale i went aftermarket because my summers are 110 degrees lol. Have an adjustable controller so i can set it for 180-200 degree turn on temps. Quote Link to comment Share on other sites More sharing options...
