Hi, I,ve diagnosed my thermostat is stuck open, takes ages to warm up and gauge indicates 60 whatever. Checked sensor with boiling water and gauge reads 90 so all OK here. Problem is I cant find where the thermostat is! taken off the housing on RHS but its not in here.

Can anyone tell me where its to be found?
