Question about 2005 Ford Freestar
When I unplug the cht sensor it runs. Changed cht sensor
Check your thermostat it my not opening all the way

Generally, the sensor is not telling the computer to activate the fan relay. Since you unplugged the sensor and forced the fan to run, we know the sensor, fan motor, and relay work.
So it could be a problem with what the sensor is telling the engine computer, or a circulation problem.

some water from the tail pipe is normal but if the car is running bad then it is possible the head gasket is blown. on the escorts that i have owned i have found that the main relay is usually burned and needs to be replaced. it is possible that the fan is dragging and burning this relay up if this relay is good then you may be better off taking it to the electrical shop.

try to replace the hoses, they may be collapsing, then replace the thermostat, and give it a radiator flush to clear any possible clogs in the lines, last thing i would say is to replace the fan

SOURCE: coolant temp sensor
no this is not true if you Unplug the coolant temperature sensor while the engine is running. This
should cause the fans to turn on low then kick to high
Typically when the engine computer loses the signal from the coolant temp sensor, it just turns both fans on high so the engine will not overheat. i hope this helped you.

did you check weather power is coming to the fan. please use the multimeter to check the power available.if the power is available to the fan wire then check the terminals to which it has been connected.
