You combine this with an engine and suspension that can handle the road too and you have the complete vehicle. With the proper care, a BMW 740iL can run many miles and for many years.

If you continue driving your BMW like this, you may experience some very expensive yet avoidable repairs. You may just need to add coolant because your 2003 BMW 530i coolant reservoir is low on coolant or you may have a more serious problem.

A Leak

Generally, if your BMW is overheating, then you may have a problem with the radiator or it may be a simple as you needing an e39 expansion tank replacement. The radiator sits at the front of your vehicle just behind the grille. Its purpose is to cool the engine by cooling off a mixture of water and coolant before it travels to the engine of your car. The liquid that flows into the radiator follows a path through small tubes where air from a fan decreases its temperature. The fluid continues to follow this process the whole time you drive unless you experience a leak somewhere like in your 2001 BMW 530i coolant expansion tank. If the liquid leaks out, then you won't have anything to keep your engine cool.

Check the Level

The coolant reservoir is a plastic bottle that holds the extra coolant. As coolant heats up it expands and flows into the reservoir or expansion tank. If this was not in place, then you would lose the extra coolant out of the cooling system and deposit on the street. If it is leaking you may want to add the proper coolant type very soon or do a BMW Z4 expansion tank removal so your car cools properly. To check the level, you can simply look at the reservoir and see if it is low. Take caution to be very careful because the coolant liquid can be very hot. If you need to do an expansion tank replacement, don't worry because it is a simple change.

Replacement Cost

If you decide to do a reservoir replacement in your local repair shop you will spend a couple hundred dollars for a job you can manage yourself. A lot of that money is for labor. With some tools, some extra time, and a couple great videos showing the process you can do the work on your own and save that money.
