Running Temp.

I fitted mine there to give a better idea of coolant temp rather that cyl. head temp. I think that if it runs low on coolant it would give a warning of that as well.

My understanding (and someone please correct me if I am wrong) is the thermostat only opens around 91-93 degrees, so you would expect to see that sort of temperature range.

I have seen my engine probe go beyond 100 on a number of occasions. In fact, that was what tipped by off that my thermostat was faulty, and since having it replaced has fixed the problem.
