Does not include the coolant level sensor or cap
Your BMW expansion tank is an important part of the cooling system. It allows the coolant a place to expand and cool down. It is also an area that is under high pressure when your engine is operating. With age, this expansion tank can crack causing a coolant leak. We recommend replacing the expansion tank when installing a new radiator to ensure continued performance and service life of your BMW’s cooling system.
Engine Coolant Reservoir
The engine coolant reservoir, also known as an ‘overflow bottle’ is a crucial component of modern vehicle cooling systems. Its job is to capture the increased volume of engine coolant that is created as the coolant is heated and expands. It needs someplace to go, so a coolant line that typically runs from the radiator outlet to the top of the engine coolant reservoir will feed the reservoir, while the reservoir feeds the engine as it needs more coolant to send through the engine and back through the radiator.
Engine coolant reservoirs are typically made of plastic and can be either clear or opaque. Some performance or aftermarket overflow bottles are made of aluminum or other more durable materials.
