After replacing a failed lower radiator hose and filling the cooling system I wanted to make sure the electric radiator cooling fan was working properly.
My Alldata service information says the fan should come on at 221F then stop running when it lowers to 200F. I usually run the engine at about 1500 rpm with the car sitting still while watching the conditions are being met. I want to mention that my Ford service information is less precise about the temperature but says the fan should come on when the temperature gauge passes halfway and turn off when it returns to halfway. The half way point being normal for the conditions. I'm bringing that up because that is exactly what the car did. The engine coolant temperature at just past half way was 210F and that is when the fan came on, at returning to half way the fan turned off at 204F.
A scan tool graphing the data shows the engine was at 176F when the recording began and peaked at 210F.
. You can see the graph lowering from the 210F to the 204F before it turns off the fan and begins the cycle again.
The system looks to be working properly.
