Car owners should pay close attention to fluid leaks, as they could indicate a serious problem under the hood.
Being able to identify different fluid types can help determine whether it’s a minor issue or something that requires immediate attention. Here’s a quick guide to understanding which fluids are dangerous and which ones are not:
Types of Car Fluids and What They Mean
- Motor oil – A black or dark brown puddle under your vehicle could indicate an oil leak. It often has a burnt rubber smell.
- Brake fluid – Usually yellow or brown when old and dirty.
- Coolant (Antifreeze) – Can be pink, orange, or green. It’s sticky and has a sweet smell.
- Gasoline – If the puddle smells strongly of gas, and it’s near the front of the engine, there could be an issue with the fuel pump.
- Transmission fluid – Typically red in color.
- Water – Sometimes, a small puddle of water forms under the car, which is just condensation from the air conditioning system. This is harmless.
When Should You Worry?
If the leak is coming from brake fluid, coolant, gasoline, motor oil, or transmission fluid, it’s time to visit a mechanic immediately.
- Oil leaks may seem harmless, but if the oil drips onto a hot surface, it can ignite.
- Gasoline leaks are extremely dangerous. If you smell gas or see a leak, do not start the car. Instead, call a tow truck and take it to a repair shop. Starting a car with a gas leak is highly risky and can lead to an explosion.
To avoid costly repairs and safety hazards, always follow your vehicle’s maintenance schedule and visit a mechanic at the first sign of a fluid leak.
