The car is overheating and we think it is the thermostat. Do you know where it is? The upper radiator hose looks like it goes right into the intake and the lower one goes up into the engine under the coil pack

The car is over heating. Our mechanic said that we need to replace the thermostat. They are charging way too much money and we want to replace it our selves. However, we do not know how to locate it. Can you provide a drawing and easy instruction on how the replce this part?

If you follow the upper radiator hose to the engine, it should lead you to the thermostat housing. If it doesn't, let me know what engine you have.
