I think I finally found the source of a coolant leak. With the engine running, I see a drip coming from the small hose that comes off the thermostat housing cover. I am not sure where this hose goes other than to the right side of the car somewhere under the expansion tank. Looking at the pictures on the parts list, is this the By-Pass hose XR8049188?
If it is, will I be able to see the other end if it after removing the expansion tank?


I don't do very many repairs myself anymore but this just might be an exception.
