Why is My Car Leaking Water?

Service Technician Working Under Vehicle

If water is leaking from under your car, it’s not likely serious. In most cases, your air conditioner is just venting condensation build-up. It could also be a trip from condensation in your tailpipe. That said, serious issues aren’t off the table. If your car is leaking water in Caledon, read our overview of all the possible causes. If you get the feeling that your car needs a diagnostic, explore our service specials, and then reach out to Mercedes-Benz Brampton for help! 

Identifying the Cause of Leaking Water

Is water leaking from under your car? If so, Orangeville drivers will need to determine which part of their car is leaking water. Here are the steps you’ll need to take to locate the source of the leak: 

  • First, place a sheet under the leak. If the leak isn’t clear, it’s likely some other fluid than water. Once you’ve determined that the leak is water, move onto the next step.
  • If there’s a large puddle of water, it’s possible that a blown gasket is causing coolant from your radiator to be burned along with the fuel. If this is the issue, there will be large amounts of water and white smoke coming from your exhaust pipe.
  • You’ll want to inspect your coolant levels to make sure they haven’t fallen. If you notice that your coolant reservoir is low and there’s a large puddle of water under your car, get your vehicle to our service garage ASAP. 
  • The other common culprit is a cracked windshield wiper fluid reservoir. If water freezes in this reservoir over the winter, it can cause the catch to crack and leak. It’s possible the leak is coming from a cracked windshield wiper fluid reservoir. If there’s an ever-so-slightly blue or green hue to your water, it’s likely windshield wiper solution.
