Mk2 16v coolant sensors

Blackie36 · Jul 28, 2018

Hi,Ive replaced the 3 coolant sensors on the bulk head and only got coolant coming from 2 of them does that mean there is a blockage?

Thanks

that is correct, 2 of the holes are cut into a coolant channel, and one is not

Thanks again for your help much appreciated

The one that’s not cut out to the coolant does that sensor go to the ecu?

I believe the blind hole is for the isv controller sensor, other 2 are ecu and clocks? probably doesnt really make a great deal of difference

Cheers mate,Do you know where I can buy the sensors as I’ve tried GSF and Vw heritage and can’t see them?

Yeah I’ve seen that style but only one of my connections are like that the others are a straight spade connection

Both styles will work either way, just for the button style you got to pop the spade out of the plastic housing
