This thermal energy causes the engine coolant to expand. But where does this surplus coolant go? It’s directed right into your trusty coolant expansion tank, a specifically designed reservoir that can handle fluctuations in coolant volume. The coolant contracts as your engine starts to cool, creating a suction effect.

This vacuuming phenomenon pulls the fluid from the tank back into the core cooling system, regulating the coolant levels regardless of the engine temperature fluctuations. This cyclic exchange of coolant, a seamless back-and-forth motion, is pivotal in maintaining the engine within its optimal operating temperature. In this regard, one could liken the coolant-expansion tank to a maestro, flawlessly conducting the rhythmical movement of coolant within your car’s cooling system.
