Research on Expansion Tank for BMW 540i

The BMW 540i is a high-class sedan and has high-quality parts and systems. That doesn't mean the expansion tank won't eventually develop a crack or break. If it does, then vital engine coolant will be lost and this can lead to major damage. Any time a car overheats it is a serious situation. Plastic expansion tanks do last, but also fail at the most unexpected of times. Fortunately, they don't cost much to replace and you can save even more by obtaining a brand new tank from an online supplier.

Signs You Need E39 Expansion Tank Replacement

The expansion tank is connected directly to the cooling system and radiator. Coolant that expands due to heating is stored in this plastic container. A cold engine doesn't put much pressure on the cooling system, and a heated engine requires more coolant; the tank is often pressurized as well. An expansion tank therefore has multiple functions. If it starts to fail, you may notice that coolant levels are consistently low and you have to keep adding more. A small crack can cause coolant to seep out or even evaporate so slowly it's hard to notice. Larger coolant leaks occur in older tanks or those that overheat. You'll see it as a steam, but a leak can drip or pool up on the ground. Engine overheating is a common result of, for example, damage to a 2001 BMW 530i coolant expansion tank. Overheating can seriously damage the engine, which can be very expensive to repair or replace.

How Does the Overflow Tank on a Radiator Work?

An expansion tank or radiator overflow tank is designed to hold coolant that has expanded with heat. The fluid is stored until it can be recycled back into the system. Once coolant loses heat, it contracts and can be returned to the coolant lines and engine. Coolant loss is prevented with the extra storage provided by the BMW E39 expansion tank, as it is with the radiator cap as well.

How Do I Drain My Coolant Tank?

Draining a coolant tank requires a lift or jack stands. The radiator cap must be removed and the coolant can be collected with a large drain pan. Some expansion tanks have a pressure cap, so remove this to drain it. Next, open the drain cock, and you can then drain the tank and the radiator.

Price of Replacing an Expansion Tank

To replace a BMW 540i tank, the price can vary, as it does with a 2003 BMW 530i coolant reservoir. You could spend anywhere from $40 to $120 on the part. Then there are the labor charges, taxes, and other possible fees. For the tank itself, you can save a great deal by going to PartsGeek.com, whether you need the tank or an E39 expansion tank hose as well. Our low prices are thanks to minimal operating costs, as everything is sold exclusively online, so you can find automotive parts and accessories that are affordable and correct any problems in your BMW.
