I am having a coolant leak in my daughter's 1998 Honda Accord from a location I have yet to identify. The leak is coming from what appears to be a sensor (maybe) below the water pump and attached to the engine housing (I think). It's definitely not a hose or the water pump itself. I can see where the leak is coming from I just cannot identify the part to replace. See attached photo, it is the gold/brass colored object with a small hose attached to its exterior.

Have you tried to put pressure in to the coolant system yet so you can locate the leak?

 

take better pics or even a detailed video showing the exact location of the leak
