Find your top radiator hose, follow it to the engine block, where it meets the engine block is a housing that contains the thermostat.
It must be replaced with one of the same temperature rating, and the spring side faces the engine, not the radiator. If you install it backwards, you will do irreparable damage to your engine with overheating.
Get the right part, install it the right way.
Suspect your water pump. Look at the weep hole on it. Is it leaking water? Time to replace it. A little in the way of a gray deposit is OK there, but fluid coming out of it is not.
