Basically, this tank handles the extra coolant volume as your engine heats up and cools down. Coolant expands when it gets hot, and contracts when it cools. Instead of just letting that pressure build up or creating a vacuum, this tank gives the coolant somewhere to go. It’s like a little reservoir, holding the overflow. It also helps maintain the correct pressure in the cooling system, and often includes a sensor that can tell you if the coolant level is low. It’s a pretty crucial part of your cooling system. The cooling system, of course, keeps your engine from overheating. The expansion tank sits inline with the radiator and engine, and it's designed to catch any coolant that gets pushed out from the radiator due to heat expansion. Then, as the engine cools, the tank can pull that coolant back into the system. It works hand – in – hand with the radiator cap to keep everything stable. If this tank fails, you’ll notice if you’re lucky. It could start leaking, which obviously leads to coolant loss and overheating. But sometimes it can crack without obvious leaks, and then your system isn’t properly sealed. That can lead to air getting into the system, which is bad news. Air pockets can cause overheating or even damage to the water pump. A failing expansion tank will really put a strain on the rest of your cooling system. You can find a good replacement online at places like Fixparts Online, and it's usually a fairly straightforward repair. It’s much better to deal with a faulty tank than to deal with the consequences of a severely overheated engine.
