This is what the Welltempered maker says, Bob
Some testing done recently showed that the actual temperature of engine coolant differs from the read temperature by about 10 degrees at operation temperature. At first I had to think is this the sensor reading incorrectly? But how can they, since they are calibrated during manufacture to within 1%?
Further testing with the infra-read thermometer shows that the sensor reading is in fact spot on... on the surface of the housing where it's mounted. But there is a difference between the surface temperature on a coolant housing to the actual coolant temperature. Makes sense really.
Thing to keep in mind once you know what the standard operating range is to look out for when the temperature goes outside this .
