Coolant tanks typically used on modern vehicles to hold any overflowing coolant from the radiator are commonly made from semi-transparent plastic bottles which may be pressurized or not. Once the engine heats up, the coolant also tends to expand, growing into an amount that the radiator can no longer hold. Instead of letting the overflowing coolant spill out into an overflow tube, vehicles now make use of the coolant tank to store this excess. With this important function, coolant tanks are also referred to as coolant reservoir tanks, coolant recovery tanks, coolant overflow tanks or coolant expansion tank, like your Honda expansion tank. Your Honda expansion tank actually serves your Honda's engine cooling system in more ways. Other than acting as a reservoir for the overflowing coolant, it also makes checking the system's fluid level a lot safer and easier. Most of the modern engine cooling systems would even permit the use the coolant tank cap for bring additional coolant instead of using the radiator pressure cap. The expansion tank is very important for the proper operation of the engine cooling system in the same way that the fuel tank is vital to the vehicle's engine.
