Why Is My Car Leaking Water?
You’re driving a precision-tuned luxury sedan or SUV and discover a puddle underneath it a few minutes after you’ve parked. You keep up with your service appointments; how could such a thing happen?
- First: Don’t worry. If your car is leaking water, that’s actually pretty common — usually from your beloved BMW‘s air conditioner or exhaust.
- Second: Read on to learn more about why your car may be leaking water and what to do if that puddle isn’t water.
How to Identify the Cause of Water Leaking from Under Car
- Place a sheet of paper on the ground where the leak is dripping. If the fluid is something other than water, the paper will be colored. If it’s blue, yellow, or green, your vehicle might be leaking coolant.
- If there’s more than a small amount of water leaking from your exhaust, it could be the sign of a blown gasket, which could be causing the coolant to be burned along with fuel. This causes large amounts of water and smoke to come from the exhaust pipe.
- If it’s coolant, you can usually spot it by its color, but you can also check the coolant level. If it’s low, you should bring your car to your local Chicago service center to have it checked.
- There could also be a leak happening because of a cracked windshield wiper fluid reservoir. This can happen if you use water in your windshield wiper fluid. The water can freeze and expand, causing the plastic of the reservoir to crack. If the leaking fluid if light green or light blue and leaking by your front tires, this is likely the cause.
What Fluid Is Leaking From My BMW?
If the fluid leaking onto the paper isn’t clear, it’s not water. That means there’s a fluid leak. Depending on what color it is, these are the fluids that could be leaking:
- Red: Transmission Fluid or Power Steering Fluid
- Orange: Transmission Fluid or Radiator Coolant
- Yellow: Radiator Coolant
- Green: Antifreeze from Water Pump, Hoses, or Radiator
- Blue: Windshield Wiper Fluid
- Pink: Power Steering Fluid or Transmission Fluid
- Dark Brown: Brake Fluid or Older Engine Oil
- Light Brown: Newer Engine Oil or Gear Lubricant
