This high quality Genuine BMW expansion tank is used on the S85 V10 engines, and is a common failure item. Be leary of competitors selling this part for less -- is it a Genuine BMW? Probably not. We only carry the Genuine BMW brand expansion tank as it is the only one we use in our own BMWs. If you are overhauling your coolant system, now is the time to consider preventative replacing this expansion tank. 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. While replacing the expansion tank we recommend replacing the level sensor (sold below) as these are also common failure items.

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.

This item fits the following BMWs:
2004-2010 E60 BMW M5

The coolant expansion tank in your vehicle gives additional fluid a place to go after expansion and contraction from temperature change. Because it is subjected to such drastic changes on a regular basis, it can often crack or break. You want to keep all the coolant in your vehicle in the cooling system. If your tank has experienced damage such as cracking, nipples breaking off, or mounting point damage, you will need to replace it.

The coolant expansion tank acts as a reservoir for excess coolant as it expands and contracts with temperature changes. Over time, the constant exposure to extreme heat cycles can cause the tank to crack, break, or suffer damage to its nipples or mounting points. To keep coolant properly contained within the system, a damaged tank should be replaced promptly.
