How to Identify Vehicle Leaks


Leaks from your vehicle will destroy the pavement and give you a clear indicator that your vehicle needs repairs. Modern vehicles use different types of liquids to keep a car or truck working properly. Some leaks corrode not only the asphalted surfaces, they harm the environment and can potentially harm the fauna and humans. Know what kind of fluid flowing from your vehicle will allow you to diagnose where the leak came from.



  • Check the sidewalk directly under the vehicle’s crankcase. Light brown or dark brown spots indicate an engine oil leak. Over time, motor seals will deteriorate and allow the engine oil to seep into the engine.
  • Check the roadway towards the middle of the car or a truck for leakage of transmission fluid. Transmission fluid appears brown and has a finer consistency than the typical engine oil. If a reddish liquid appears to come from the face of the vehicle, this may indicate a power steering leak.
  • Look below the entire clear vehicle with slightly brown fluid. If the liquid has an extremely smooth consistency, this may indicate a braking system that leaks and requires troubleshooting as soon as possible.
  • Check rear-drive vehicles for a leaking rear differential. A thick black fluid dripping from the rear axle of the vehicle indicates a defective differential seal.
  • Check under the front of the vehicle for green, yellow or fluid pink standing on the surface of the liner. This viscous liquid indicates a problem with the cooling system. Overheating will cause the engine coolant to overflow and spread in the environment.


Tips and warnings

Do not alarm yourself if small amounts of water is discovered under the vehicle after the performance of the air-conditioning system. The water leak is a natural condensation from the air conditioning system.
