It is part of your identity and most owners take care of it like it is part of the family.

Expansion Tank 101

Without a properly functioning expansion tank, your BMW can overheat. The expansion tank is a vital component to your heating and cooling system. This system is first filled with cool water from your supply line. Then the pressure of the expansion tank is equal to the supply line pressure, keeping the diaphragm pressing up tightly against the tank. As the temperature of the water in the system rises and your BMW 523i expansion tank expands, it pushes against the air cushion to absorb added pressure. As the system pressure is becomes greater, excess coolant is forced out the radiator and into the expansion tank.

Basically the tank's ability to compress absorbs excess pressure that occurs as a result of thermal expansion. It keeps the rest of your system from being damaged due to excessive pressure.

Is My BMW 325i Expansion Tank Malfunctioning?

Problems with your BMW 325i expansion tank can result from either a leakage or blockage, or could indicate a bigger problem leads to a complete malfunction. To determine whether your BMW 325i expansion tank is malfunctioning, be on the lookout for a few potential problems.

A pipe wrench, old towels and the type of waterproof tape that plumbers use are on the short list. Follow all directions carefully.

The first clue that you need a BMW 325i expansion tank replacement is simply excess water. As the heated water expands, as explained above, its physical volume increases and that creates pressure. If this extra water is blocked or damaged, the water has nowhere to go and you have a leak.

A Potentially Explosive Situation

If gauges or valves are damaged, the water in-flow and out-flow is disrupted and excess water build up can occur. This creates a somewhat dangerous situation because the tank could explode. Take care with your BMW 325i expansion tank removal. It can be done but care must be taken to avoid accidents.

Sometimes there is excess water condensation. This is often because the tank is holding too much water. Condensation problems also occur in high humidity. That is why you see so many cars overheating in the summer. But keep your cool. There is a solution. A new expansion tank will cost you roughly between $51.95 to $125.95.
