Where is the thermostat located on a 93 Toyota Camry V6

Followed the upper hose but came up empty, where I thought it would be it isn't. Bottom hose maybe?

Thermostat is mounted to the water pump on the front of the engine. This goes to a water inlet pipe which hooks to the lower radiator hose.

Thanks guys, I found it. I can't figure out why they chose to go against tradition and put it where they did but, oh well, it is what it is. Thanks again for your help.

I guess they have their reasons! My first response was made based off theory, not research. When I got your response, I was intrigued and actually looked it up. Sorry if I steered you wrong initially! Best of luck.
