Hey guys do you know the wrench size for the Coolant Temp Sensor? m22 size nut.
indeed, i was wrong. i dont know what half of the stuff in this car is honestly.So you are talking about the fan switch on the radiator, NOT the "Temperature Sensor" on the thermostat...?
That does look like a 29mm spanner or deep socket is required and they do exist.
They may not be in the usual sets of spanners/sockets, but they are available individually.
