This is my wifes car, so this is all second hand. She had said there was a rattling noise and that it stopped after a loud clunk. I open the hood and find that the radiator fan had sliced through one of the wires that are zip tied just above it. I also found this little guy and the other end of the wires all chewed up.



It appears to be the hood latch sensor as it looks like something was quite possibly ripped from that area.

Now further issue is that it does not show an indicator or issue with the hood being open. Assuming that the sensor is missing, should it not indicate something like that?

Also, when driving the car temp gauge says it warms up fine (from my wife here on) And then after a few miles she says the temp drops all the way to "C" (cool) at highway speeds after just a couple miles.


So my question is... IS that the hood latch sensor? If so, whats the part number or if you have a link to where i can order it that would be fantastic.

Is the cooling issue due to the sensor, (or as i think) or is it possibly another separate issue?

We did just have the Timing belt, water pump stuff done... also replaced the power steering rack (and my wallet thanks you for the sympathy).

I will check my hood this morning.

Second, there is something wrong with your temperature sensor. Time to replace it. While a stuck open thermostat can drop the temperature at highway driving a few degrees, it will never go down to cold.
