Follow the upper radiator hose to the engine, the Thermostat is under the Thermostat housing that the upper hose attaches to at the engine. If you go to Auto Zone and pick up the Thermostat, they can give you the step by step instructions to replacing the thermostat with common tools and should take you no more then 30 min to do. Note: make sure you replace the antifreeze lost with a 50/50 mixture or just replace the whole coolant in the system since they have a life time of 100,000 miles of 5 years and it looks like your 5 years are up if it's never been replaced. The dexi cool is know to crystallize and cause flow restriction through out the coolant jackets in the engine. Good luck and hope this helps, keep me posted.
