Dude-Seriously...Understand what something does before you speak about it. The T-Stat controls the operating temperature up to its opening specifications. After that, the most a stat can do is limit flow of water. To a fault if its of poor design. On some systems the stat will slow water down to aid in the transfer of heat from the engine. Pass water to quick and the heat never leaves the metal to the water.
