How to Identify Types of Automotive Fluids

If your car sprung a leak in all of its major systems, you would have a colorful canvas on your garage floor. Fortunately, that is not likely to happen. While different cars have different motors, all cars have similar fluids that make them run properly. It is a good idea for you to know what the major fluids in your car's engine look like.

Instructions

1. Look for leaks in the oil lines if you see dark amber to brown spots under your car. Check the car's oil filter and around the drain plug. Service centers change oil in many cars daily. Sometimes the technicians forget to wipe these down and tighten them properly. Be sure to check the engine's oil level before you start the engine if you do see drips.

2. Note any fluorescent-colored liquid on the floor. This is probably anti-freeze. Depending on the chemicals in the brand you use in your car, anti-freeze is usually fluorescent green or orange.

3. Inspect any clear fluids you may see. Brake fluid goes into the car clear but turns amber with usage. Power steering fluid also goes in clear and turns darker with age. Signs of either of these on the floor need your immediate attention.

4. Check out your car's transmission if you see red or pinkish-colored spots. A car's transmission system is a closed system so the fluid stays pretty much the same color while it's in the transmission line.

5. Feel any wet spots. If the spots are oily, they are probably one of the above fluids. If the spot is just wet and it's a hot day, chances are the air conditioner is dripping condensation onto the floor.

Tips & Warnings

• Be sure to wipe up any spots on the garage floor. Anti-freeze in particular is poisonous to pets.
