Coolant sensor leaking, what is the sensor?
I have a 2003 Super Duty 7.3l. I have a sensor located directly behind the idler pulley that is leaking coolant (all over my belt). I purchased a coolant temp sensor from NAPA, but that is not it. It is bigger and a two prong sensor. If that sensor is on top of the engine and right in front of the fuel filter, this sensor is wyed into it on the harness. This sensor is not screwed into the block, but into a piece of tubing. Does anyone know what this sensor is and what the Ford or NAPA part number is? NAPA cannot tell me what the sensor is, maybe they do not sell it.
Thanks
Thanks

The coolant temp sensor goes right into the water pump.

I replaced mine a few months ago from O'Reilly Auto Parts. Here is a link to the one I have:

I could not see the pic you sent. I will try and post one tomorrow. To answer your question, they sold me a coolant temp sensor. I have coolant leaking, i believe from what you are saying is the ebp sensor. The truck runs perfect, i just noticed the leak a few days ago.
