I had a good run today and I'd say the new deflector plate made no difference whatsoever. Still gives an indicated 96 once fully warmed up at 40 to 50 and got up to 102 at 70 on a long gentle hill, just about 100 at 70. The fan didn't come on as far as I could tell. I will leave the plate there to see what happens in the summer.
It seems like the thermostat is controlling the inlet temperature to the engine and the dashboard water temperature gauge is reporting the outlet i.e. 88 deg inlet constant but the more the load the higher the outlet temperature.
