Brake Fluid

Brake fluid is a clearish light brown color and will feel slimy to the touch. A leak will most likely collect in a puddle near a tire or under the brake master cylinder. If you believe you have a brake fluid leak do not drive your vehicle as you could completely lose your ability to slow and stop your car.


The fluid used by the cooling system is generally a bright green color, but can also come in pink or yellow, depending on the type you're using and smells very sweet. Coolant is poured into the radiator and then moves through the cooling system to prevent vehicle overheating.

Transmission Fluid

Transmission fluid is a reddish color and will collect directly under the transmission if there is a leak. This fluid is vital for proper gear shifting so be sure to contact your mechanic right away if you suspect a leak.

Differential Fluid

Differential fluid looks very similar to transmission fluid. The best way to tell the difference is by the location the leak is collecting in the driveway. If it is at the front of the vehicle it is a transmission fluid leak, at the rear it is a differential leak.

Engine Oil

Probably the easiest vehicle fluid to identify, engine will appear black after it is used. Some engine oil leaks do not need immediate attention but should be monitored. Talk to your mechanic about the oil leak your vehicle is suffering from to see what the best course of action is to take care of it.
