Cars and trucks rely heavily on multiple fluids in order to properly operate their numerous systems. The hydraulic mechanisms of your vehicle allow it to run, drive and stop safely and reliably. These fluids are vital to the operation of your vehicle, so anytime you think your vehicle may have a leak be sure to get the issue checked out right away by a professional mechanic. To help describe the problem you’re having to the mechanic use this guide to try and identify what the fluid may be. These are the most common fluids that leak from cars, trucks and SUVs.

Engine Oil

The most simple fluid to identify is also the most common one that leaks. Oil is generally black or light brown and it will leave a nasty stain in the driveway. As Oil runs through the motor it may be able to seep from many different places where there are gaskets and seals. Some leaks don’t need immediate repair, while others are crucial. Ask your mechanic for honest advice.

Brake Fluid

Brake fluid is a clearish, slightly brown color and is slick to the touch. If you believe you have a brake fluid leak do not drive your car as there is a good chance that your vehicle will have very limited, if any ability to brake.

Transmission Fluid

Transmission fluid is often dyed a red to help distinguish it from other vehicle fluids. If your transmission begins to leak the fluid generally accumulates underneath the passenger cabin. Transmission fluid leaks usually appear at the seal between the engine and transmission.


Coolant has a slimy feel and is most often a bright green color, however it also comes in yellow pink. Coolant leaks need to be addressed immediately, as this fluid helps to prevent your engine from overheating. Coolant may leak from the radiator itself or from a connecting hose.

Differential Fluid

Differential fluid  and feels appears very similar to transmission fluid so the best way to differentiate the two is by noticing where the leak is coming from.If the fluid is collecting near the back of the vehicle it is probable that it is coming from the differential.
