2.6L thermostat housing - is this the same thing as water outlet?

Looking around for parts and having a hard time finding a thermostat housing. I found something that the internet says fits the truck, but its called a water outlet. It looks like the thermostat housing, but I was unsure. What do you think?

if it looks the same, it should be the same. They are probably using the GM designation for it, but be sure they take returns before you buy.
