What Fluid is Leaking from My Car?

Noticed some fluid leaking from your car? Vehicles use a variety of fluids, so it’s important to identify which fluid type is puddling in your driveway in order to avoid mechanical or safety issues. Use this guide to determine which fluid you may be dealing with, and make an appointment with your mechanic to have the issue properly diagnosed.

Transmission Fluid

If the fluid leaking from your car is red in color, it may be transmission fluid. Transmission fluid ensures that your car can shift smoothly, and operating a vehicle that is low on transmission fluid can cause major damage. How can you be sure that’s the issue? If transmission fluid is leaking, it will almost always drip from under the forward section of your car’s passenger cabin.

Differential Fluid

Differential fluid looks and feels similar to transmission fluid, so the easiest way to tell the difference is to notice where the leak is coming from. If the leak is near the rear of the car, it is much more likely to be differential fluid than transmission fluid. Have a mechanic investigate the issue in order to be sure.

Brake Fluid

Brake fluid leaks generally accumulate near a tire or under the brake master cylinder. Brake fluid is clear or light brown color and will feel slimy to the touch. A brake fluid leak is very dangerous and warrants an immediate trip to the mechanic to ensure your stopping power is not hindered — don't drive your vehicle if you suspect a brake fluid leak!

Coolant Leak

Coolant leaks are most easily identified by color — coolant is usually bright green, but it can also be pink or yellow. Coolant keeps the engine from overheating, which can do major damage, so it’s vital that coolant leaks are repaired right away.

Oil Leak

Oil leaks may be the most common kind of fluid leak. Oil ranges in color from black to light brown, depending on how recently the vehicle’s oil has been changed, and can seep from many places. If you notice an oil leak, it’s important to have a mechanic determine the severity of the issue to find out how quickly it needs to be repaired.
