Well not really a quiz.
I have a sensor spare are the moment and before I put anything else on the engine I want to make sure that I have not missed out anything obvious.
I have fitted the oil pressure swith, oil pressure sensor, 3 sensors on the thormostat housing and one on the end of the illet manifold.
i have this one left over
It looks like a radiotor coolant sensor, but that it still in the radiator.
Any ideas?
