Blue fluid leaking from car: If something in your car starts to leak, the easiest way to identify what the fluid is and where the leak is coming from is by looking at the color of the fluid. Generally speaking, all the fluid in your vehicle can be classified as clear, red, black or brown, orange, light yellow, blue, or yellow/pink/green.
We’ve all been there: You get out to your vehicle only to notice a mysterious liquid leaking from your car and pooling on the pavement. To make matters worse, you can’t even address the problem before you figure out what the fluid is. This is often easier said than done since your vehicle uses many different fluids to function properly.
Fortunately, Jerry’s super car insurance comparison app is here to help. We’ve put together the following guide detailing everything you need to know to identify what kind of fluid is leaking from your car and what to do about it.
What fluid is leaking from my car?
Your vehicle uses many different fluids in its operation, which means that identifying a fluid leak can be more difficult than it seems. Start by identifying the color, and if it’s not certain, you can examine the texture, smell, and location of the leak.
Clear Fluid
Most of the time, any clear fluid that leaks from your vehicle will be water, especially if you notice the leak on a hot, humid day after the air conditioner has been running for a while. Your vehicle’s air conditioning system uses an evaporator to remove moisture from the air, which means it accumulates water over time. This water then leaves your vehicle through a small tube and drains onto the ground.
Red Fluid
If the fluid is red, it is most likely a power steering or automatic transmission fluid leak. That being said, these fluids do not stay red throughout your life, but rather start to turn reddish-brown or brownish in color over time.
For this reason, you may need to rely on a few other qualities to identify which fluid it is. If the fluid is thin, feels oily, smells like burnt marshmallows or burnt cooking oil, and collects under the steering rack, it’s power steering fluid. But if the fluid is slippery and smells more like petroleum, it’s transmission fluid.
Black, Brown, or Amber Fluid
If your vehicle is leaking black, brown, or deep amber fluid, it is likely motor oil. Depending on how long it has been since you last changed your oil, engine oil can be amber in color or take on a much darker brown or black color once it has become contaminated with particles.
An oil leak will always happen under your engine, but the engine is not in the same place for all vehicles, and the engine can leak oil from many different places. It is best to have a mechanic take a look if you find oil under your vehicle.
Differential fluid is also dark brown or amber in color, but it has a very distinctive, almost greasy odor that distinguishes it from motor oil. Most of the time you will find this fluid leaking from the rear differential, stock transmission and/or rear axle seals.
Orange Fluid
A puddle of orange fluid under your vehicle usually indicates a coolant leak, although coolant is not usually orange. However, rust can build up in the cooling system and turn the coolant a reddish-orange color. Test it by touching and smelling it; if it feels slimy and smells very sweet, it’s an oxidized coolant.
Automatic transmission fluid can also turn orange the longer it sits in your vehicle, but it doesn’t feel or smell the same as coolant. If the fluid smells like petroleum and is slippery to the touch, it is transmission fluid.
Light Yellow Liquid
If you see light yellow liquid under your vehicle, do not drive it. The fluid is most likely brake fluid, which means the brakes will not work properly.
However, the longer brake fluid sits around, the darker it becomes, which means it can be difficult to identify by eye alone. If you touch the fluid and it feels slippery or oily, and you smell fish oil, you have a brake fluid leak.
If you find that brake fluid is leaking from your car, call a mechanic as soon as possible; You may also need to call a tow truck to bring your car to the repair shop.
The blue fluid
coming out of your vehicle is probably windshield washer fluid.
However, if you drive a Honda, the blue fluid may be windshield washer fluid or coolant. You can easily tell them apart by their smell: the windshield washer fluid will smell like your typical cleaning solution, and the coolant smells incredibly sweet.
Yellow, Green or Pink Fluid
If you notice yellow, green or pink fluid coming out of your vehicle, it is probably a coolant leak. You can confirm this by smelling the fluid, as coolant has a very distinctive sickly sweetish odor.
If there is a coolant leak from your vehicle, in which case it will collect under the engine, do not drive your vehicle. Driving your vehicle when it is leaking or low on coolant can cause your engine to overheat, which can result in expensive damage.
What to do when you have a fluid leak
Whenever you discover that there is a fluid leak in your vehicle, you should always try to identify it before doing anything else, as this will determine your next steps.
Most fluid leaks aren’t indicative of immediate vehicle failure, which means you’ll be able to drive to the nearest auto repair shop with no problem, but if you identify the leak as brake fluid or coolant, you’ll want to call. a crane. This will help you avoid having an accident or irreversibly damaging your engine.

Find out which fluids are leaking by fluid color
Your car fluids need to stay in place while they do their job. Sometimes things go wrong with the parts that hold these fluids in place and cause leaks.
You can find out which fluids are leaking based on their color after reading this guide.
- Light Color – A leak that is clear usually means it is a water leak. The water usually comes from the air conditioner during regular condensation. This is not something you should worry about. If you are concerned that it may be something else, please bring it to our service department where we can check the leak for you.
- Orange Color – If you see an orange color or a color close to orange, it could mean there is a transmission fluid leak. Check the center of your car for leaks of this fluid, as it is the most likely place for transmission fluid to leak.
- Light Yellow to Dark Brown – These colors tell you there is a brake fluid leak and indicate a problem with your vehicle’s brake system. Brake fluid changes color over time, which is why there is a wide range of colors.
- Light brown to black: This means you have an oil leak. Light brown means the oil is relatively new, while black implies the oil has been used and recycled a bit. Oil leaks can tell you that your oil pan is leaking or that there is a problem with your engine.
- Green Color: A green fluid leak from your car is most likely an antifreeze leak. Antifreeze typically leaks from your vehicle’s water pump, hoses, or radiator when fittings, hoses, clamps, or other components have become worn or not attached properly.
- Blue – Blue fluid leaking from your vehicle is most likely windshield washer fluid. Over time, the fluid reservoir and the tubing that carries wiper fluid through the wiper blades can degrade.
- Pink: The pink fluid leaking from your car is likely power steering fluid or transmission fluid. These leaks are usually caused by a worn seal or a hole in the return line.
If you see a leak, you should take your vehicle to a mechanic. Think of it as a symptom of a larger problem. If you don’t deal with the symptoms, they will become a bigger and more expensive disaster to deal with.
Frequently Asked Questions
What does a pale amber fluid mean for a car?

What does a very thick fluid mean for my vehicle?
Gear oil is a thicker fluid found in cars with manual transmissions that has a distinctive odor. Gear oil in manual cars tends to leak slowly, so watch for early signs like odor or dirt buildup in specific areas under the vehicle.
How is the power steering fluid?
Most modern cars come with power steering. It’s easy to miss a power steering fluid leak, especially since it’s similar to transmission fluid. Knowing where to look is the key to identifying a power steering fluid leak. Although, if you’ve noticed that your vehicle’s steering has become more difficult recently, the cause could be a fluid leak.
