Where is the thermostat located on a 1999 Chevy Cavalier and can you show a picture of the thermostat location?

I'm no car guy so my descriptions aren't great, but I just changed mine so I know this one. On the 1999 2.2 engine it's located inside the hose that connects your coolant reservor and your radiator collant intake. If you stand in the middle of the frount of your car its low and just left of center (close to the very frount probably by your left leg). You disconnect the hose held on by two small bolts and all the collant will come flooding out. PLEASE put something under the car before doing this! After you get the hose off you just pull out the old one. put a new seal on the new one and replace it. Jack up the front of the car or park it facing up hill to replace all that coolant. it will take a couple gallons.
