When you walk out to your driveway and notice a mysterious puddle under your vehicle, it’s natural to worry. A car leaking fluid can mean a minor issue or a serious problem that requires immediate attention. But how do you know what you’re dealing with?
While different leaks may look similar at first glance, the color, location, and texture of the fluid often reveal the source of the problem. In this guide, the ASE-certified technicians at ABS Unlimited Auto Repair in Fairfax, VA break down the most common fluid leaks, what they mean for your car, and why it’s important to act quickly when you spot one.
Why You Should Never Ignore a Fluid Leak
Leaks are one of the earliest warning signs that something isn’t quite right. A small spot today can grow into a bigger repair tomorrow if left unchecked. Fluids keep your vehicle’s major systems running smoothly: they lubricate, cool, and power components you rely on every day. Losing any of them can put your safety and your car’s health at risk.
At ABS Unlimited Auto Repair, we often hear customers say, “It’s just a few drops.” But those drops may indicate:
- Engine damage if oil leaks persist.
- Overheating and breakdowns caused by a coolant leak.
- Transmission failure from low fluid levels.
- Loss of steering control from a power steering fluid leak.
That’s why our team recommends having leaks diagnosed as soon as possible. With digital vehicle inspections (DVIs), we send you pictures and videos of what we find, so you can see exactly where the leak is coming from before making decisions about repairs.
Common Types of Car Fluid Leaks
Each type of automotive fluid serves a specific purpose. Below, we’ll cover the most common leaks you may notice under your car and how to identify them.
Engine Oil Leak
An engine oil leak is one of the most common and potentially damaging types of leaks. Oil keeps your engine lubricated, preventing friction and overheating.
How to identify an engine oil leak:
- Color: Typically brown or black (fresh oil may be amber).
- Texture: Slick and greasy.
- Location: Usually under the engine or toward the front of the car.
Possible causes:
- Worn gaskets or seals.
- Loose or damaged oil filter.
- Cracked oil pan.
Ignoring an oil leak can lead to serious engine damage or even a seized engine. If you notice oil spots, don’t wait, schedule a professional inspection.
Coolant Leak
A coolant leak is also a common culprit. Coolant (or antifreeze) helps regulate your engine’s temperature, especially in extreme heat or cold.
How to identify a coolant leak:
- Color: Green, orange, or pink depending on the type of coolant.
- Texture: Thin, watery, sometimes sweet-smelling.
- Location: Under the front of the car, often near the radiator or hoses.
Possible causes:
- Worn radiator hoses or clamps.
- Cracked radiator.
- Failing water pump.
Driving with low coolant can quickly lead to overheating, blown head gaskets, or warped engine parts. This is a leak that should be fixed immediately.
Transmission Fluid Leak
Your transmission is one of the most complex and expensive components of your vehicle. Transmission fluid ensures smooth gear shifting and protects internal parts.
How to identify a transmission fluid leak:
- Color: Bright red when new, turning brown as it ages.
- Texture: Oily but thinner than engine oil.
- Location: Typically under the middle of the car.
Possible causes:
- Faulty transmission pan gasket.
- Damaged seals.
- Transmission cooler line issues.
Because transmission repairs can be costly, catching and fixing a transmission fluid leak early can save you thousands.
Power Steering Fluid Leak
A power steering fluid leak can make steering difficult and dangerous. This fluid allows you to turn the wheel smoothly and with minimal effort.
How to identify a power steering fluid leak:
- Color: Usually red or reddish-brown.
- Texture: Thin and oily.
- Location: Toward the front of the car, often near the steering rack.
Possible causes:
- Cracked hoses.
- Loose connections.
- Worn-out seals in the steering system.
If your steering feels stiff, you hear whining noises when turning, or you notice fluid on the ground, it’s best to have your system inspected right away.
Other Fluids You Might See
While oil, coolant, transmission, and power steering fluid leaks are the most common, there are other possibilities:
- Brake fluid leak: Pale yellow to brown, very slick, and dangerous if levels drop.
- Windshield washer fluid leak: Light blue or green, watery, usually harmless but still inconvenient.
- Fuel leak: Clear with a gasoline smell—this requires immediate attention due to fire risk.
Diagnosing a Fluid Leak: What You Can Do at Home
If you notice your car leaking fluid, here are some steps you can take before heading to a shop:
- Check the color: As noted above, color is the biggest clue.
- Note the location: Front, middle, or rear under the car.
- Look for warning lights: Many modern vehicles have sensors for low oil, coolant, or brake fluid.
- Monitor the size of the leak: Is it just a few drops, or is the puddle growing daily?
While these steps can help you narrow things down, they aren’t a replacement for professional diagnosis. A certified technician, like those at ABS Unlimited Auto Repair, has the tools to pressurize systems, check seals, and trace leaks to their source.

FAQs About Car Fluid Leaks
How do I know what fluid is leaking from my car?
You can tell what fluid is leaking from your car by checking its color, location, and texture. Oil leaks are brown or black, coolant is green or pink, and transmission fluid is red. These clues help narrow it down, but a professional inspection ensures accuracy and safety.
Is it safe to drive with a coolant leak?
No, it is not safe to drive with a coolant leak because it can cause the engine to overheat quickly. Overheating may damage the head gasket or engine block. Even a small coolant leak should be checked right away to avoid costly repairs.
What color is transmission fluid?
Transmission fluid is usually bright red when new, turning dark red or brown as it ages. If you see red fluid under your vehicle, it’s likely a transmission leak. Fresh fluid should also smell slightly sweet, while burnt or old fluid has a harsher odor.
Why is my car leaking oil?
Cars can leak oil due to worn gaskets, a damaged oil pan, or loose drain plugs and filters. Oil leaks often appear as dark spots under the engine. Even small leaks should be repaired quickly, since low oil levels can lead to severe engine damage.
Can low transmission fluid cause a leak?
No, low transmission fluid doesn’t cause a leak, but leaks are the main reason levels drop. Common sources include worn seals, cracked lines, or a faulty transmission pan gasket. If you notice slipping gears or red fluid on the ground, your transmission should be inspected promptly.
