Why Fluid Color Matters

Every vehicle relies on a network of fluids to keep things running smoothly—coolant, oil, transmission fluid, brake fluid, and more.
Each has its own color, texture, and smell. When you see a colored leak under your car, that’s your vehicle’s way of asking for attention.

At Chami Automotive, we help drivers in Houston and Sugar Land, TX quickly identify leaks before they become expensive repairs.

Understanding the Colors Under Your Car


Fluid Color

What It Usually Means

What To Do

Clear Water

Normal condensation from A/C system

Safe — no action needed

Light Brown / Black

Engine oil leak

Schedule an oil leak inspection immediately

Bright Red / Pink

Transmission or power-steering fluid

Tow or drive carefully — low fluid damages systems

Blue / Light Green

Windshield-washer fluid

Simple refill, check for hose cracks

Green / Orange / Pink

Coolant or antifreeze leak

Do not drive — risk of overheating

Yellow / Gold

Brake fluid leak

Stop driving — critical safety issue

💡 Tip: Dab the fluid on a white paper towel — feel and smell help confirm which system it’s from.

1. Engine Oil Leaking (Brown or Black)

Old oil smells burnt and feels slick. Leaks usually start at valve-cover gaskets or oil pans.
Ignoring this can lead to engine damage and smoke.

Fix: Have Chami Automotive perform a UV-dye oil-leak inspection to pinpoint the source.

2. Transmission or Power-Steering Fluid (Pink or Red)

A pinkish spot beneath the center or front of the car signals a seal or line failure.
If shifting feels delayed or the steering whines, stop driving and call us — these systems depend on clean, pressurized fluid.

3. Coolant Leaks (Green, Orange, or Pink)

Coolant protects your engine from overheating.
Leaks often stem from worn radiator hoses, water-pump seals, or cracked overflow tanks.

🚨 Danger: Driving with low coolant can warp your engine head or blow the gasket.

4. Brake Fluid (Yellow or Clear)

Even a few drops are serious. Brake fluid absorbs moisture and loses pressure quickly when leaking.

🛑 Warning: If your brake pedal feels soft, park immediately and have your car towed to Chami Automotive for a same-day inspection.

5. Washer Fluid (Blue or Light Green)

This is harmless, but if it’s constantly low, check for cracked hoses or a loose reservoir cap.

Why Early Detection Saves You Money

Catching leaks early means minor gasket replacements instead of full system rebuilds.
Houston’s high heat accelerates seal wear, making routine fluid checks essential for longevity and safety.
