Product Information

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 Recovery Tank

Your vehicles expansion tank gives coolant a space to expand and contract as it goes through temperature changes. This tank is subjected to tremendous pressure and extreme heating and cooling cycles. This of course can cause cracks which result in coolant leaks. If your expansion tank is showing signs of leaks it must be replaced immediately.

Engine Coolant Recovery Tank Failure Symptoms
  • Visible coolant leaks coming from tank
  • Cooling system cannot pressurize
  • Low coolant warning light

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
