What is a BMW 330Ci expansion tank?

As your engine heats up and the contents of the radiator expand, pressure is exerted against the inner walls of the system. Sometimes, this pressure causes radiator fluid to expand to the point where it needs somewhere to go. In the old days, this might cause the radiator cap to blow off. Modern vehicles like your 330Ci have an overflow tank to prevent loss of coolant and damage to the sensitive sensors and electronics located in your engine compartment.

How much is a new BMW 330Ci expansion tank?

These parts are relatively simple, and tend to cost somewhere between $35-120. The price depends on the model year of your 3-series and the company that manufactures the part. Make sure to inspect all of your hoses when you replace your expansion tank: you save money doing all the coolant system work you need at once.

What are the signs of a failed BMW 330Ci expansion tank?

The most noticeable sign of a bad BMW 330Ci expansion tank is visible leaks. It's also important to keep an eye out for:

  • Quickly dropping coolant levels
  • Engine temperature lights
  • Low coolant levels
  • Wet spots around or beneath the tank

If you see any of these, you might have a leak somewhere in your coolant system. Do a thorough inspection and replace any parts that are worn or aged.
