While there are many parts of your cooling system that are larger and require more frequent attention, your Buick thermostat is essential to the proper operation of your cooling system. A small and relatively inexpensive part, your Buick thermostat serves to control the flow of coolant into the radiator, and thus controls the temperature of the engine. The fluid carries the heat that it collects as it travels its winding path and if it cannot enter the radiator to allow the fluid to be cooled because a malfunctioning thermostat has not allowed the radiator to open, your engine could overheat. When a malfunctioning Buick thermostat permits frequent overheating of the engine, that overheating can have disastrous effects on the engine, as the excessive heat can destroy seals and gaskets, as well as warp metal parts and surfaces. It can even lead to the dreaded head gasket replacement. Replacing your Buick thermostat is a simple repair task, and won't take much of your time or any out of the ordinary tools to perform.
