Why Is My BMW Vehicle Leaking Water?

car leaking liquid



If your car is leaking water, and not some other service fluid, the issue you’re facing probably isn’t very serious. Water leaking under a car is often the result of natural condensation on your air conditioning system. If it’s pooling near your tailpipe, you might be dealing with condensation on the exhaust. Either way, you most likely have nothing to worry about.

Keep reading to find out when you should worry about a car leaking water and learn how to identify other types of leaking fluid at home in Ontario, CA or the greater Los Angeles area.

Identifying the Cause of Leaking Water

  • If there’s a lot of liquid pooling beneath your vehicle, you should check the color. The fluid coming from a car leaking water will be clear.
  • A little water by the exhaust is nothing to worry about. A lot of water coming from the exhaust could indicate a blown gasket. You’ll likely also see a significant amount of white smoke.
  • If you can’t get a good read on the color of the leaking fluid, you might wonder if you’re dealing with water or coolant. Checking the level of your coolant is always a smart way to check your results.
  • Leaking windshield wiper fluid is also common since freezing temperatures can cause the reservoir to crack. Once again, you’ll want to get under the hood and check the level manually.

If you’re ever unsure of why your car is leaking water, or if you think there may be a deeper issue, it pays to schedule service and check out our other BMW service tips and tricks.

What Fluid Is Leaking From My Car?

As we noted above, checking the color of the fluid is the easiest way to tell if you’re dealing with water leaking from under the car, or if you’ve got another problem on your hands. Remember that no matter what kind of fluid you need, you can pick up a BMW-approved product at our BMW parts department. You can order genuine BMW parts online here.

Since getting a read on the color of the fluid can be tricky on concrete or on gravel, place a sheet of paper or bleached cardboard beneath the leak. Then, reference the table below:

  • Red fluid is usually transmission fluid or power steering fluid.
  • Orange fluid is usually transmission fluid or radiator coolant.
  • Yellow Fluid is almost always radiator coolant.
  • Green fluid is usually antifreeze from the water pump, hoses, or radiator.
  • Blue fluid is usually windshield wiper fluid, although some antifreeze can take on a blue tone.
  • Dark brown fluid is either brake fluid or older engine oil.
  • Light brown fluid might be gear lubricant, but it’s more likely to be fresh engine oil.
  • Pink fluid is either power steering fluid or transmission fluid.

If you’re still not sure of the kind of issue you’re facing after checking the color, a peek under the hood may be helpful. For example, if a leaking red fluid is pooling beneath the transmission, it’s probably that kind of fluid, and not power steering fluid.
