What is this part called?
While trying to figure out my electrical mystery problem I noticed a wet spot on the front of my engine. It seems to be coming from this black water, um thing? behind the exhaust headers. It's probably not visible with the stock exhaust manifold, but I can see it pretty well with my headers. It looks like it connects the water pump to the thermostat housing. I think it needs replaced, but I don't even know what it's called?
