just like the title...i think its behind the water pump near the thermostat...but im just double checking

I thought the coolant temp sensor was on the bottom of the radiator??? I could be wronge. Or on the lower part of the water neck. https://www.nopistons.com/forums/pub...IR#>/dunno.gif https://www.nopistons.com/forums/pub...IR#>/dunno.gif https://www.nopistons.com/forums/pub...IR#>/dunno.gif

I don't know about an s5 TII, but I'm pretty sure the water temp sensor is just to the left of the oil pressure sender at the back of the block

for the gauge cluster gauge it's by the oil pressure sender on the rear iron as said above.. but there is also one in the water pump housing which i'm guessing the ecu uses for it's dedicated purpose only.

so where is the water temp sensor for a s4 t2?

sooo when im putting in a water temp gauge...where do i put the sensor in

If you dont mind having a dead gauge, just put it where the stock one was/is right next to the oil pressure sending unit.



If you do mind having a dead gauge on your dash, take off the waterpump and have it drilled/tapped to accept your new sending unit.

well i have a "dead" water temp gauge and i can't figure out why

dead sensor / wire / motor ? whatever is in there is dead



hmm....mebe ill tap it

Good excuse to drain/flush/change your coolant while youre at it.
