Where is the thermostat located on a 1997 Nissan 200SX?

Answerthe thermostat is not on the upper hose of the radiator as most cars you have to folow the lower hose in the radiator all the way in the back of the engine you will find out that the thermostat is right behind the cap of the engine oil on top of the power.

On top of the power what? The engine oil cap is way above the lower radiator hose.

Yeah I am kinda of lost too. Power what? Oh well. My thermostat is fine but I will need to replace mine at some point. I think the thermostat is at the lower part of the rad hose is what he means. The upper it could be as well, depends on year.

When you are looking at the engine, it is on the left backside of the engine. You will see a hose going to the engine block. Take the hose off at the block area and then remove housing on block. the thermostat is inside.
