Features

  • Replacement Radiator Coolant Expansion Tank - The coolant tank contains coolant fluid that is discharged from the cooling system attached to the engine. Pressure builds up and released when the coolant is hot and expanding through the radiator and when the engine cools down, the excess fluid flows back into the radiator from the coolant tank of your vehicle. If you are experiencing leaks, low levels of coolant, and an overheating engine then you may have a problem with your coolant tank.

  • OEM Fit, Quality, Finish - While this is not a genuine OEM part, it is a direct replacement and will look, fit, and work exactly like the factory part. The radiator coolant overflow expansion tank's common issue is leakage which can cause an overheated engine. Safely turn off the engine and let the temperature drop before opening the radiator's cap or the coolant tank to reduce and release the pressure safely.

  • Part was defective, with loose pieces inside. I missed the return window, so I'm out of luck.
Size: 1999-2005 3 Series Models
The part sent was defective, with loose pieces inside. When I took the cap off and turned it upside down, a metal retaining clip came out. Part is obviously defective as shipped. Missed the return window, so I couldn't return a useless part.
