Radiator / Engine coolant temp sensor location

New to the Forum
Seem to have a radiator fluid leak around the top of the engine valve cover passenger side. Not exactly sure we're it is coming from, but appears to be from the area of a sensor. Could this be the the engine / dashboard temp sensor? Does it have a small basket that could have gone bad?pls help.

I myself also have an engine coolant leak on my 07 that I'm working to self diagnose. Put some dye in it this morning. Did you ever find an answer to your own question? Hopefully I target my leak location today.

Coolant leaking above the passenger side valve cover sounds like the Y or tee connection at the passenger compartment heater hose.



Motorcraft KH-509
Ford part #8L1Z-18472-A

About $60 or so.

What could leaking from the radiator on the passenger side indicate?
