Have you ever found a wet spot under your car and had no clue where it came from? Don’t panic – your fluid’s color holds the clue to the leak’s source! As a driver, it’s important to understand how different liquids work together to keep your vehicle running smoothly. But leaks, if not addressed, can lead to bigger issues.

Rather than playing detective trying to trace back false leads, learn to let your fluid’s color do the talking!

By familiarizing yourself with fluid identification basics, you can pinpoint potential problems quickly without a mechanic’s help. Let’s start:

Transmission Fluid: Red

One of the biggest leaks to spot and address, automatic transmission fluid (ATF) is typically red in appearance. If you notice crimson red puddles by your transmission or transfer case, this is likely the cause. Check fluid levels regularly to monitor for small seeps before they worsen. While red, ATF can also discolor over time to maroon or rusty hues, depending on mileage.

Coolant: Green or Orange

Engine coolant keeps your motor from car overheating with its mix of water and glycol. Most conventional formulations today are green, while some manufacturers use orange. Either way, radiator or hose leaks produce telltale shades of these colors. Coolant stains engine bays, so don’t confuse it with surface dirt.

Power Steering Fluid: Amber or Red

Helping wheels turn with each control motion, power steering fluid (PSF) takes on a light amber or red transmission fluid-like tint. Look under the steering rack and reservoirs for signs of seepage indicated by similar hues. Replenish PSF levels regularly to counteract internal component wear.

Brake Fluid: Light Yellow or Brown

Used less conspicuously than drivetrain liquids, brake fluid maintains critical hydraulic functions. It may appear a light yellow or clear, depending on additives. Check beneath your master cylinder and lines, especially near the wheels, for fluid changes on paint, hoses, or suspension.

Engine Oil: Black/Brown

We’ve all seen oil leaks in action as the fluid darkens with contact and vehicle use. Fresh oil runs amber-brown, transforming darker with mileage—an oil pan or valve cover leak stains noticeably with unmistakable shade changes. Pay attention to distinguishing drips from general road grime buildup on undercarriage components over time.

Windshield Washer Fluid: Blue

This seasonal refill earns an honorable mention. Washer fluid spillage appears brightly blue against any surface, making winter top-offs or hose cracks instantly recognizable. Don’t dismiss puddles of this helpful liquid, as they can damage finishes left untended.

FAQs

What does purple fluid leaking from a car indicate?

Purple fluid typically suggests a leak in the power steering system or coolant. European cars often use purple antifreeze, and power steering fluid may also come in this color. Sometimes, it could be transmission fluid also.

What does red fluid leaking from a car mean?

Red fluid usually points to a transmission or power steering fluid leak. It’s important to check for leaks near the transmission or steering components.
