Why Is My Car Leaking Water?


If your car is leaking, it could signal a serious mechanical issue. However, it’s likely that your car is leaking water from the a/c system — which is normal, or from the exhaust — also normal. Still other water leaks are caused by window seal issues, or sunroof issues, which are more serious. Then, there’s the case of vehicles leaking other fluids like coolant or brake fluid, which you may mistake for water at first glance. Either way, we invite you to contact us at the Allen Samuels Auto Group service center if in doubt as to why your car is leaking water.

Identifying the Reason Your Car is Leaking Water

Is water leaking from under your car? Follow the below steps to find where exactly it’s coming from:

  • Put a sheet of paper under the leak. If it’s blue, green, or yellow, it’s probably coolant, not water. This could signal a serious issue or just a small intermittent leak. If it’s clear and odorless, it’s likely something much less serious.
  • If more than a small amount of water is coming from your exhaust as condensation or a tiny drip, a blown gasket could cause coolant to burn up with the fuel, creating white smoke out of the exhaust pipe.
  • Not sure if your car is leaking water or coolant? Check your coolant level! If it’s low, you’ll want to bring your car to a certified service center like ours ASAP.
  • It’s possible that water leaking from under your car is coming from a cracked windshield wiper fluid reservoir if you’ve used water in the reservoir. If you’ve used windshield wiper fluid (as is strongly recommended) the paper test should let you know. Another tip to tell if water or windshield wiper fluid is what’s leaking? Wiper fluid leaks are usually found by the front tires.
