Why do plastics get brittle when they get cold?
-
A key factor in the molecules’ ability to slip and slide is temperature. Specifically, there is something called the “glass transition temperature” (Tg), which is the point below which an amorphous solid (such as glass, polymers, tire rubber, or cotton candy) goes from being ductile to brittle. For most common materials, says Rutledge, this temperature is so high or so low that it is not easily observed - the Tg of window glass is 564 degrees C, and that of tire rubber is -72 degrees C.

The thermostat is the “watchdog” of a car’s cooling system. It constantly monitors the temperature of the system and regulates coolant flow through the radiator. It operates many times each day during driving. A good thermostat speeds engine warm-up and regulates the engine’s operating temperature, which results in good fuel economy, lower emissions, better engine performance and longer engine life.
So, when replacing the thermostat, be sure to use a reliable Gates OE quality thermostat.
Gates thermostats provide a precise fit to help prevent leakage. Their temperature sensitive heat motor allows precise engine cooling, in order to guarantee optimum engine performance.
