Genuine BMW BMW Coolant Expansion Tanks for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

On certain models, namely E36, E46, and E90, the factory BMW expansion tank is prone to either breaking at connection points or blowing apart altogether. If you're starting to feel like your expansion tank is on borrowed time, it's probably time to replace with either a direct OE replacement, or strengthen your cooling setup with an aluminum expansion tank - we offer numerous performance upgrades for your expansion tank. Especially if you're someone who likes to track your BMW, we recommend upgrading your expansion tank to avoid ruining your track day.

We have found that the expansion tanks should be replaced based on age as well as condition. Expansion tanks seem to have a lifespan of less than six years before they show signs of fatigue and wear. Pre-emptively replacing the expansion tank as part of an overall maintenance plan can prevent you from getting stranded from a sudden failure later on.

This radiator coolant reservoir/expansion tank for E46 M3 is a common failure item as the plastic weakens over time and stress crack will lead to coolant leaks. If your car has over 80k miles and hasn't had one of these replaced, we highly recommend it during your next major service. We have found that the aftermarket coolant reservoirs fail easier than the original BMW piece so we only offer the BMW type on this part.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.
