If it's a dark brown or black color, it's time to change the oil, and if you see a milky color, it means that coolant is leaking into the engine. With all the combustion and friction that goes on in an engine, it produces a lot of heat. Coolant (also known as antifreeze) works to keep everything, good, cool, by absorbing heat from the engine and dissipating it through the radiator. Maintaining the correct coolant level prevents overheating.

If you've ever driven a classic car, the first thing you probably noticed was the super heavy steering. Can you imagine trying to park in parallel? Modern cars have incorporated power steering to facilitate maneuvering at any speed, and many power steering systems are hydraulic and use pressurized fluid to turn the steering wheel effortlessly (although some newer models now use electric steering). There's no set deadline for replacing power steering fluid, but you still need to know how to check it. The importance of your car's brakes needs no explanation.

The brakes of modern cars are hydraulic, meaning that the fluid connects the pedal to the brakes themselves.

It's supposed to happen instantly: if there is any delay or abnormal feeling in the brake pedal, the first thing to check is the fluid. Over time, brake fluid can become contaminated with water, which can rust brake lines.

Leaks can also form, causing a spongy pedal feel or uneven braking performance. Most cars have a brake fluid reservoir in the engine compartment, and checking it is as simple as looking at its level and color.

Inspect the liquid level as well as its condition. It should be amber or red in color and have a soft touch. As with other fluids, if it's dark, cloudy, or sandy, it means there's a problem that needs to be inspected.

To add transmission fluid, pour it into the filling tube if your vehicle has one. After checking the fluid level in the rod, move the gear selector through the gears with your foot on the brake to help the new fluid flow through the transmission. Transmissions are complex equipment, so if you're still having problems, it's best to contact a professional. Windshield washer fluid has no effect on car performance, but it's still vital for safe driving.
