Help identifying a sensor
Hello C4 experts
Cant find the pic etc of this sensor in the FSM
On drivers side between #1 and 3 cyl
87 stock engine
Accidentally broke it. Seemed to have a ceramic top and brass pin. When I unscrewed it coolant came out of the block.
Knock sensor?
Coolant temp sensor?
Connector is shown with one green / white stripe wire.
Please help!
Many thanks as always!

Yes fan switch for the AUX FAN GM# 14043276 or an equivalent. In the FSM if you have the EDM (Electrical Diagnostic Manual) 8A-201-2 Fig A
