temp sensor in end tank

[WreckITFrank]

I bought a 300tdi (metal tank) rad that was damaged in shipping. I have to take it to a local rad shop to have some minor repair and testing, and want them to put in a sensor port while they are fixing it. I may put a revotek fan on there (already own one), or simply use it for a temp alarm or something. Id rather use the tank than cut into the upper hose and add a port that way. Anyone have any recommendations on what size/thread to put in there? I assume for a fan i can use any relay/sensor kit I want, but i dont have one yet and figured id ask here. TIA

I typically use SPAL fan switches that are available in either 195F or 185F (I use 195F). They are 3/8” npt

Just out of curiosity, have you done any research on temp sensor placement? I’ve always wondered about putting them in the radiator

not a terrible amount, but the rad guy told me where its placed should be close enough the upper hose temp, where most cut in and place a sensor. Brass tank makes it easier, as he said putting in a plastic is doable, but more likely to fail. I think alisport puts theirs in rad as well. ill find out I guess once i test it out.

Makes sense, I normally mount them in the intake of a RV8
