Mercedes ML500 Replacement Expansion Tank Information


Your Mercedes ML500's expansion tank, otherwise known as the engine coolant recovery tank, is what contains the boiling hot radiator fluid issuing from your engine coolant system as the temperature and pressure within the system cause overflow to escape through a pressure relief valve built into the radiator cap assembly. Without this pressure release something would have to blow, like a hose or the radiator cap, which is often what happened in older cars before expansion tanks came into use.

Because these tanks are made from plastic and susceptible to extreme temperature variations from freezing cold weather to boiling hot liquid, they are prone to developing cracks and leaks, which basically renders them useless. A replacement expansion tank designed for the Mercedes ML500 is not expensive or difficult to replace, and PartsGeek.com stocks the original equipment part made by OEM provider Behr. This is high-quality at low, wholesale prices.

So far I am pleased with my replacement Expansion Tank. Although the tank didn't exactly fit on to it's screws, it fit well enough. The cost of the tank and the speed of the delivery makes this a very good purchase. I highly recommend Parts Geek.
