Toyota engine system is the very soul of the vehicle. For it to function efficiently, it needs to produce high level of thermal energy. But the engine itself cannot control the production of heat that is why cooling system is created to take off the excess heat from it. The coolant, an important component of a cooling system, has a direct contact with the engine since it circulates throughout the engine system to absorb the excess heat from it. And because the coolant absorbs heat, it expands. Good thing Toyota expansion tank is there to save this coolant. Along with other cooling system parts, this expansion tank is not meant to last long. The hard work it does for the cooling system will also require replacement in due time. When it fails, you should obtain only a high quality Toyota expansion tank replacement. An expansion tank is connected to the radiator through an overflow tube. The moment the coolant expands, it will find extra space to go which the radiator doesn't have. And it is the expansion which provides enough room for it. Without it, the coolant will exit through the overflow tube and simply get spilled. As the cooling process is repeatedly done, more and more coolant will be wasted. When there's no longer enough coolant for the vital task, the engine will most likely to overheat. Aside from storing the expanded coolant, the expansion tank also prevents bubbles from forming in the coolant. Such can decrease the coolant's ability to absorb heat.
