Your radiator fans will no kick on until the coolant temp reaches 206.2 degrees-F
That will be low speed.
At 215.6 degrees-F high speed will kick in.
Dash temp. gauges are sometimes not very accurate.
So you could check fan function and accuracy of your dash gauge by hooking up your Durametric and watch the coolant temp. while the car is idling. That way your seeing the same temp. the DME/ECU is seeing.
Let the temp. get up to 206-208 and see if the low speed fan function triggers.
This will also allow you to compare the coolant temp. your DME/ECU sees to what your dash temp. gauge shows.
