Thermostat location 2000 grand prix 3.1

[alwaysneedhelp]

This may be a stupid question, but where is the thermostat located on a 2000 grand prix, 3.1 ltr? I found a lot of information for the 3.8, but can't find out where it is on the 3.1. Any links with pictures with also be helpful.

Thanks

Follow the upper radiator hose to the engine. The aluminum piece it hooks to is the t-stat housing. It bolts in under the throttle body, and is difficult to near impossible to do with the throttle body installed.
