Keeps the temperature gauge centered. That's all I can ask for. Over 1 year old and still working perfectly. The supplied gasket is too thin, causing the thermostat to sit loosely in the engine block. I wasn't happy with this so I used an old OEM thermostat gasket and then a new one. The thermostat itself is much weaker than the original. It made me nervous to use it, but so far so good. You get what you pay for.
