Leaks are not something you just see on the ground. Because, it could be a liquid, gas or even air.
The most common visible ones are: Coolant, Oil, Brake Fluid, Power Steering Fluid, Antifreeze and Transmission Fluid.
The ones that you don’t see include: Vacuum, Compression and Fluids Mixing Together.
A vehicle is filled with many different fluids, and any one of them at some point, can turn into leaks. These fluids can leak when a mechanical failure occurs, leaving a puddle in your driveway or garage. Identifying a fluid is critical to determining, how to fix the problem.
One of the first things to do is to confirm the color of the fluid. Next, feel it. Is it slippery? Finally, smell it. Certain fluids have a distinct smell.
