Why Is My Car Leaking Fluid? What Each Color Means and What to Do

Noticing a mystery puddle under your vehicle can be alarming. If you’re wondering why is my car leaking fluid, you’re not alone — fluid leaks are one of the most common reasons drivers visit a mechanic. The good news? You can often tell what’s leaking just by looking at the color and location of the fluid.

In this guide, we’ll explain how to identify the most common automotive fluids, what they mean, and when to bring your vehicle into Marble Falls Auto Center.

Clear or Slightly Brown Fluid: Water (Usually Normal)

If you see a small puddle of clear water under the front passenger side of your car, don’t panic — it's probably just condensation from your air conditioner.

• Usually odorless

• Appears on hot or humid days

• Not sticky or oily

What to do: Nothing! This is normal. But if you're not sure, bring it to Marble Falls Auto Center for peace of mind.

Green, Orange, or Pink Fluid: Coolant Leak

Coolant (also called antifreeze) helps regulate your engine’s temperature. If you see green, orange, or pinkish fluid near the front of the car, it could mean a leak in:

• Radiator or hoses

• Water pump

• Heater core

What to do: Don’t wait! Overheating can cause engine failure. Our team at Marble Falls Auto Center can pressure-test your system and fix any leaks fast.

Why Is My Car Leaking Fluid? What Each Color Means and What to Do

Red or Reddish-Brown Fluid: Transmission or Power Steering Fluid

Red fluid is typically transmission fluid, but if the leak is near the front of your vehicle, it could also be from the power steering system.

• Transmission leaks may occur near the middle or rear

• Power steering leaks usually show near the front wheel well

What to do: These systems are vital. Low fluid can lead to major failures. A certified technician should inspect both immediately.

Brown or Black Fluid: Engine Oil Leak

Motor oil is the most common leak and usually appears under the engine area.

• Light brown if new

• Dark brown or black if old

• Slippery to the touch

What to do: Small drips might seem harmless but can become costly over time. We’ll inspect your oil pan, gaskets, and seals to find the source and prevent engine damage.

Yellow or Light Brown Fluid: Brake Fluid

Brake fluid is rare to see on the ground — and when you do, it’s serious.

• Typically found near the wheels

• Slick and slightly oily

• Can be clear, yellow, or light brown

What to do: Do not drive! Leaking brake fluid compromises your ability to stop safely. Call Marble Falls Auto Center immediately for a tow or inspection.
