Coolant Expansion Tank - E85 E86 Z4

This high quality Genuine BMW brand expansion tank is used on M54 and N52 engines, and is a common failure item on all E85 Z4's. Be leary of competitors selling this part for less -- is it a Genuine BMW? Probably not.

If you are overhauling your coolant system, now is the time to consider preventative replacing this expansion tank. These are known to go bad, causing a leak which can leave you stranded. 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.

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.
