There are two (2) Radiator fans, the one on the driver side seems to work properly, the passenger side fan does not seem to work.
I check the passenger side fan by wiring it direct to a power source (Battery) and the fan motor does work.

I assume that it is the sensor that is faulty. The wires of the fan goes into a wiring harness and it is very difficult to follow the path of the wires from the fan to find the sensor that it goes to without tearing out the wiring harness. I Don't want to do that!!

By visually looking I only see one sensor attached to the radiator, it is on the passsenger side of the radiator, is this the sensor i am looking for?

Is there another sensor somewhere else? it is the only one I see.

Is this sensor only for the one fan I only see two wires coming from it?

Also could you tell me what this part is called, it is called a Radiator Fan Sensor?

Thank You for your help

coolant level sensor is what it's called. BUT, that second fan will not kick in till 240 degrees. basically a safenet from overheating. if you replace that sensor, be sure to bleed the radiator correctly or you'll get the low coolant light pretty much constantly, even tho the level is not low.
