If it helps, LS bolts are 10x1.5. I don’t think size of the fan matters, just figure out how many amps it draws at startup and get a relay 1.5x bigger.

Yeah relay isnt an issue, I want to find a fan switch thats M12 x 1.5, everything Im finding is m14 or m16 and I dont think I can drill even for an M14 because the piece it goes in is too small, its not an LS FYI haha

Exactly what is it for ?

And why not just screw a switch into an adaptor elsewhere on the cooling system ? And is there no ecu to control the fan ?

And yes the hole in the head for the GM temp sensor is M12x1.5

Painless 30113

Just the sensor by itself
