Research on Expansion Tank for BMW Z4

BMW Z4 Expansion Tank

When you drive a BMW, you know how important it is to maintain the integrity of the original design. That’s why you seek out the highest quality original equipment manufacturer parts and authorized upgrades. After all, with vehicles like BMWs, the precise engineering that balances every system can only be maintained by precisely manufactured parts. When you need to replace your BMW Z4 expansion tank so that your coolant has a contained space to safely expand to after it gets warm, you need to know that your replacement part will be every bit as tough and dependable as you expect.

With tons of choices on PartsGeek.com, you can find just the right expansion tank for your BMW Z4. There are selections from Uro and Vaico that meet the original design specifications for your vehicle, down to their quality of materials. You can also find genuine OEM parts that conform exactly to your BMW’s original design specs. You’ll find the same is true for all the millions of parts across the site, in hundreds of categories.

What is a BMW Z4 Expansion Tank?

This tank is also called the “overflow tank” by some people, and it is where the coolant can expand to once it has cycled through the engine and come back heated up. It allows the system to adapt to different operating temperatures, and if it is leaking or otherwise faulty, the vehicle will lose coolant while it runs.

How Much Are New Expansion Tanks?

The price can vary quite a bit, depending on the manufacturer and whether or not it is considered a “performance” part. Generally, BMW expansion tanks on the site cost between $60 and $110, with the higher end tanks belonging mostly to the genuine OEM sources.

What is the Difference Between Aftermarket and OEM?

The difference is that OEM sources held or hold the contract with BMW to produce parts for that vehicle. By contrast, aftermarket parts from manufacturers like Vaico comply with the design specifications, but they were not specifically authorized for production manufacture.
