What Is That Fluid Leaking Under My Car?

Something dripping from a car might or might not indicate a dangerous situation that needs attention. In this article I will cover the six most common fluid leaks from a car—from the leaks that will leave you stranded, to the leaks that should be in fact be happening. Yes, there are times when fluids should leak naturally from your car, and we will cover that as well. Let’s try to figure out what fluid is leaking from your car and what you should do about it.

Find the Source, Check the Color

First of all, before you start worrying, make sure the fluid leak is coming from your car and not the vehicle that was parked in that spot before you got there. Just grab a flashlight, get down on one knee, and take a good look under your car.

If the fluid is coming from your car, you need to determine the fluid’s color. The best way to do that is to slide a piece of white cardboard or a piece of plywood under your car and let the car drip onto it. Capturing the drip this way will enlighten you in two ways: one, it will reveal the color, and two, it will give you a good indication of where the fluid is leaking from. First, without moving the board, notice where the drip is hitting the board; turn your head and look up from this point at the bottom of your car and see exactly where your leak is coming from. Once you have a clear view of where the fluid is leaking from, remove the board and check the color.

Different Fluids Have Different Colors

Six Most Common Fluids to Leak from a Car

The six fluids that most commonly drip from a car are:

  • water
  • motor oil
  • transmission fluid
  • coolant
  • gear oil, or differential fluid
  • and power steering fluid.

I left brake fluid out of this list, because it’s not common for brake fluid to leave a puddle under your car. Nevertheless a brake fluid leak is potentially serious (see my article about common brake problems). Just for quick reference, brake fluid color is clear to amber, and smells like fish oil; if you doubt me, take the cap off the brake fluid reservoir and sniff the cap.

1. Water Leaking From Your Car

The three H’s--hazy, hot and humid—are probably the most common cause of fluid leaking from a car, in the eastern U.S. at least. A car’s air conditioner needs to do something with the moisture it removes from the air inside the passenger compartment. It drains the water onto the ground under the car, via a rubber hose.

On very humid days, the water will pour out of the air conditioner drain onto the ground like from a faucet, until the cabin humidity is almost gone. This is what I meant earlier when I said that some leaks are supposed to happen.

This hose is usually at the front right (near the area where the passenger rests their feet) or in the middle of the cabin. If you have a newer minivan or large SUV with front and rear climate control, it’s possible to have two evaporators and two air conditioner drains, one in front and one in the rear.

Dual Climate Control

Here's a tip: when you use the air conditioning system, it’s best to keep the recirculation button in the “on” position rather than the “fresh air” position (see picture below of the recirculation button on a Honda). If you leave the car in “fresh air” mode, it will continue to drag humid air into the car, the vehicle’s cabin will never reach optimum temperature, and sometimes when the weather is extremely humid, the air will turn into fog as it pours from your vents into your car’s passenger cabin. If you ever experience this phenomenon, reach over and push the recirculation button. The recirculated air will lose humidity on each pass through the evaporator, and your air conditioner will be working at maximum efficiency (see my article on how to defog car windows fast).

2. Oil Leaks

Engine oil, or “motor oil,” may vary in color from light amber to dark brown, depending on how well you maintain your car. If there is an oil leak, common sense tells you that it will be under the engine, but it’s not always immediately obvious where your engine is located. Don’t laugh: on a front-wheel-drive car, your engine could be located at the front left or front right, depending on where the transmission sits, and the engine could be in the rear of the car if you’re driving a Porsche or a VW bug. Once you figure out the oil is dripping from the engine, all you have to do is pinpoint the leak. You might want a mechanic to take a look at it if you can’t find exactly where it is leaking from. Oil leaks can come from some pretty obscure sources, like a crankshaft seal under the timing cover, or they can come from something easy to spot like a valve cover gasket.

If you know you have an engine oil leak, check your dipstick frequently. Do not drive a car that's low on oil. It will overheat and damage itself. If you have a massive oil leak do not drive your car at all.

3. Coolant or Antifreeze Leaks

Coolant comes in many colors now; it used to be green, but now its color depends on the manufacturer of the car or the coolant. Honda provides a blue coolant, Mercedes uses clear, Toyota uses red, and I have seen orange, green and all the colors of the rainbow. Coolant has a sweet smell, like candy, and also a sweet taste. Don’t taste it—it’s half ethylene glycol, which is poison—but I have tasted it a few times in my career, not by choice.

Coolant in the Overflow Tank

A coolant leak could be almost anywhere, because of all the coolant hoses that surround your engine. Some coolant hoses (the heater hoses) go into the passenger compartment itself. But the most common place for a coolant leak is your radiator, and that will be located behind the grill in the very front of the car.

If you suspect you have a coolant leak, you may be able to smell it. Take a quick glance at the coolant overflow tank; it is usually see-through and has “high” and “low” markings on it.

If it’s empty, or you aren’t sure what you are seeing, let your engine cool completely and look in the radiator. Do not remove the radiator cap on a hot engine. It could blow hot coolant or steam into your face and cause severe burns. If you can’t see any coolant when you are peering down into the radiator, you may have a leak.

You don’t want to drive a car that has lost a massive amount of coolant. It can overheat and ruin the engine. Keep an eagle eye on the temperature gauge. Or better yet, tow it to where it can be fixed.

4. Transmission Fluid Leaks

Automatic transmissions use red or pink fluid, and lots of it. Very often, the first sign of an automatic transmission leaking is that the transmission will start to slip (the car will rev without going into gear). If the leak continues, eventually the car will not move at all.

Automatic transmissions use fluids specially formulated by the manufacturer. If you don’t use Honda-made automatic transmission fluid (ATF) in a Honda automatic transmission, you will compromise shift quality and void your warranty, so I recommend following Honda’s guidelines and using their recommended fluids.

Standard (“manual”) transmissions use gear oil (like heavy, strong-smelling motor oil; see “Gear Oil” below) or the manufacturer's proprietary manual transmission fluid. Very old Hondas use regular motor oil in their standard transmissions.

The most common place for a transmission fluid leak on a front-wheel drive car is the axle seals; on a rear-wheel-drive car it is the output shaft seal. If you see red or pink fluid under your car, pull the transmission dipstick and check your transmission fluid level. Check the owner’s manual for the proper way to check transmission fluid, different manufacturers have different ways of checking transmission fluids. Some manufacturers don’t even let you check the fluid: the last model of the Honda Passport had no way of checking the transmission fluid—weird!

5. Gear Oil or Differential Fluid Leaks

Differential fluid, hypoid, gear oil, or gear fluid: whatever you call it, it’s very thick, it looks like honey, and it smells like a warm, greasy Mack truck sitting at a truck stop. If you get this stuff on your hands the smell doesn’t go away for days. Gear oil is dark brown, or dark amber if it’s new and clean. If your rear differential is leaking, or your standard transmission has a leak, you will find this fluid dripping. Gear oil can also leak from the wheel bearing seals or rear axle seals. Sometimes you will see oil being slung from the center of the wheel all over the wheel rim of the vehicle. Dust will collect on the wheel and turn black. If you have a four-wheel-drive car, gear oil can leak from the front axle as well. The smell alone will enable you to determine if it’s gear oil or not.

6. Power Steering Fluid Leaks

Power steering fluid is hard to describe specifically because some manufacturers use transmission fluid and some use their own brand of power steering fluid. Honda uses its own proprietary power steering fluid which is light amber in color. Power steering fluid may have a distinctive smell, kind of like burnt cooking oil. If you think you might have a power steering fluid leak, the first place you should look is at the reservoir. The reservoir will have high and low markings and it should be easy to see whether the fluid level is low. Other signs that fluid is low is that the power steering pump will whine when trying to turn the steering wheel, or the steering wheel will feel tight when turning in a parking lot or at low speeds. The most common place the power steering will leak is on each end of the steering rack. The steering rack has end seals on both sides of the steering rack; they are the first to start leaking because they go through the most wear and tear.


I Don't Recommend Using "Stop Leak"!

I have one last tip; I do not recommend using any additives that claim to stop leaks unless it is absolutely necessary. These products are at best a temporary fix that could cause a permanent problem by damaging your car's drive train. Do your car a favor and avoid using them.

Fluid Leaks From a Car: FAQ’s

Why Is There Water Leaking From My Car?

Water leaking from a car is very common, especially when using the air conditioner. The air conditioner removes moisture from the passenger's compartment and drains it under the vehicle via a drain hose. This hose is typically located under the passenger's foot well or in the center of the vehicle just below the dash area.

Something to keep in mind is that in most newer vehicles, when you are in defrost mode, the air conditioning automatically comes on to remove moisture from the windshield area to give the driver a clear view inside and out. Thus water may drip from under the passenger compartment of a newer car even if you haven't turned on the air conditioner.

What Does It Mean When Your Car is Leaking Oil?

When your car is leaking oil it usually means you have a gasket or a seal that has either been damaged or has just worn out due to age. If you notice an oil leak, I recommend you make an appointment with your mechanic to have it at least diagnosed to determine the severity of the leak.

Do "Stop Oil Leak" Products Work?

"Stop oil leak" products are not a permanent fix for any oil leak. You may even cause more leaks using the products or even worse, clog up an oil galley.

These products were designed to temporarily stop small oil leaks and I don't recommend using them unless it's absolutely necessary.

Can You Drive a Car With an Oil Leak?

If the oil leak is not pouring out of the engine, or dripping onto any hot components like an exhaust manifold, a car with an oil leak can be driven. But if oil is dripping from your car, I don't recommend driving it, because the car could completely stop running at any time and leave you stranded. Or worse, the leak could destroy your engine.

If you must drive a car with an oil leak, you will need to check your oil frequently, and you will need to be the judge of how bad it's leaking and how often it will need to be topped off.

Oil leaking from an engine can cause a huge mess wherever you park and permanently damage asphalt surfaces, so keep that in mind when parking at someone's house, especially if you like those people.

Is it Bad to Drive With a Leaking Head Gasket?

The problem with driving a vehicle with a leaking head gasket is the car can quit on the driver at any time.

When a head gasket is leaking, it can leak in many different ways. It can leak into the combustion chamber and cause the spark plugs to fail. This in turn can cause clogged catalytic converters, and cause plumes of thick smoke from the exhaust pipe.

Coolant or oil can leak past the head gasket and out the side of the engine causing either a low-oil or low-coolant condition. These can cause the engine to overheat or "seize," to stop running and start melting.

If you think you may have a blown head gasket, I recommend getting it checked so you know exactly what is wrong and whether it is safe to drive in that condition.

How Much Does It Cost to Fix an Oil Leak on a Car?

The cost to fix an oil leak can vary greatly depending on what's leaking and where. Some of the most common leaks are seals and gaskets.

The rear main seal is one of the most costly oil leaks because of the location of the leak. The rear main seal is located between the engine and transmission and the mechanic will need to remove one of these components to replace the seal. The cost is usually around $1000 or more to fix this oil leak.

How Do You Know if You Have a Transmission Fluid Leak?

Most vehicles use a red or pink fluid in the transmission which is very noticeable when you see it on the driveway or garage floor. If you don't notice the leak, eventually the transmission will begin to slip under acceleration or while driving.

What Are the Symptoms of Low Transmission Fluid?

The main symptom of low transmission fluid is the transmission slipping: the engine will rev up, but the car will not move, or it will move very little compared to engine RPM.

Another symptom of low transmission fluid is "surging": the transmission will slip in and out of gear causing a surging feeling while driving at a steady speed.

Can a Transmission Leak Be Fixed?

Yes, transmission fluid leaks can be fixed unless the transmission case is cracked or damaged beyond repair. Transmission fluid may leak from seals, gaskets, lines, and fittings.

How Much Does It Cost to Fix a Transmission Fluid Leak?

The cost to fix a transmission fluid leak would depend on what is leaking and what type of vehicle it is. The most common leak on a front-wheel drive vehicle is an axle seal. The average cost to replace an axle seal in a non-4-wheel drive vehicle would range from $200 to $400 US dollars.

In rear-wheel-drive vehicles, the most common transmission fluid leak is the output shaft seal where the drive shaft connects to the transmission. The cost to replace this seal may be a little less then than on a front-wheel-drive vehicle because there are fewer parts to be removed to perform the job.

These are the most common leaks we see on a day-to-day basis, but there are a lot more places the transmission can leak, like transmission lines, transmission coolers, and input shaft seals and gasket.

What Color Is Antifreeze?

The color of antifreeze has changed over the years and it now comes in almost every color in the rainbow. I recommend using the manufacturer's coolant, but if you can't do that, at least use the same color coolant. Mixing two different color coolants can lead to a brown coolant; it may still protect your engine from corrosion and overheating, but it doesn't look very pretty.

Questions & Answers

  • I have a leak that looks like water in the front left (driver side) in my 2010 Jeep. Could it just be from the AC or something more serious?

    If the leak is just water, most likely it is coming from the AC Drain. If the fluid is oily, it most likely will be something else.

  • I have a 2005 Chevrolet Kalos which is leaking out towards the back wheel. Its black and leaves little puddles when I park. It smells fumey. What do you think this might be?

    I think this might be moisture dripping from your exhaust system. If the fluid is watery and evaporates without leaving a residue, this may be just exhausted condensation leaking from a seam or exhaust drain hole.

  • I just picked up my car from the dealer after an oil change. Before I left, they said they found an engine oil or fluid leak, but I haven’t seen any spots on my garage floor or the ground. Should I pay the dealer the $120 diagnostic fee for them to look into it?

    It's possible your car may have a fluid leak without it reaching the ground yet. You can either keep an eye on your garage floor or find a mechanic who will clean the fluid leak and add dye to the system that may be leaking.

  • I have a small amount of oil collecting in my right wheel hub. What could be causing this?

    Maybe an axle seal leaking or brake fluid leak at the caliper?

  • I have a 2013 Toyota Camry and it is leaking water when parked and I have not used my AC?

    When you use the windshield defrost mode the AC automatically operates to remove moisture from the windshield area and passengers compartment so it's possible you are using the AC without even knowing it :)

      Hi Mike,

      I assume you meant it wouldn't go into gear? No, a leaking differential seal won't pervent it from going into gear but it would leave residue all over the back of the car. A transmission fluid leak would leave you stranded.

      Hi Angel,

      So I'm thinking the intake manifold gasket is the culprit and the only way to stop the leaking coolant is to replace the gasket. That will be a few hours labor, around $200-$400 parts and labor.

      Hello, I have a 2004 Chevy tahoe that is leaking thin, clear liquid from the front passenger side. This leak has caused my car to run a bit lean, and has drained my coolant completely. I went to get diagnostics done and it appears a 'recommended" change is for the Intake Manifold Gasket but it was not necessary to change rite of way. Nonetheless, the tahoe started leaking clear fluid until i had no coolant. Since then i have added coolant, stopped driving, qnd coolant level stayed the same.

      Hi Hundean,

      If the leak persist after a few days, I recommend you bring it back to be inspected for a defective oil filter or loose drain plug, otherwise if the leak is gone, it may have been some residual oil that wasn't wiped after the oil change.

      Hi Jacinda,

      Most likely it's the leaking power steering line, but if you want to be sure, top off both and keep an eye on them for a few days. There is a transmission cooler located at the radiator so you could have a leak there as well.

      Hi Julie,

      Any time you use your HVAC the AC system could be running as well, especially if you use the defrost. I recommend checking the AC drain for clogging, use a coat hanger or compressed air to clear the drain and see if the leak subsides.

It is hot and I have been using the AC and I know it is normal for water to leak from the AC use but I have noticed that it is leaving stain on the driveway. The liquid is clear and odorless so I really thought it was just water from AC but if it was just water it should not be leaving stains right?

      Hi Mark,

      It's sounds like your intake manifold gasket is leaking and is causing your problem. Coolant/water run through the intake so if the gasket is compromised you will loose coolant/water and the engine will overheat. Let me know if this helps, thanks.

      Green fluid is usually coolant, but it wouldn't be by the rear tire unless it was tracking under the vehicle from a front leak. I recommend having it checked just to be sure you don't have a small coolant leak. Let me know what you find, thanks.

      Hi Greg,

      Most likely you either blew a radiator hose or your radiator let go. I recommend having it towed because once the coolant is gone the engine will overheat and fail, and you don't want that. Keep me posted, thanks.

      Hi Tammy,

      Most likely your master cylinder is leaking inside your vehicle. First check the brake fluid level and add some if needed, then take a flashlight and look under the dash at the brake pedal, look up near the pivot point where the brake pedal meets the rod coming from the brake booster, most like you'll see brake fluid leaking somewhere in that area, if so, you'll need to replace the master cylinder. Let me know what you find, thanks.

      Are you sure it's oil and not water draining from the AC evaporator ? The drain is located directly below the passengers footwell under the car.

      Hi Greg,

      If the leak is in the front of the vehicle on the drivers side it may be a radiator hose or radiator itself. If it's more towards the center of the engine on the drivers side, then it's possible your water pump is starting to leak. Let me know what you find.

      Hi Emily,

      The cooling system holds about 4 gallons of coolant so you will not notice anything at first. I recommend having the system checked, it may be a hose or something small. You don't want to get stranded with an overheating engine so get it checked out asap.

      Hi Cora,

      You either have a transmission line leaking or the transmission cooler is leaking, it is located in or around the radiator. I recommend having a trusted garage look at it and give you an estimate on the repair. If it's the radiator is could get pricy, if it's just a line it would be a lot less. Keep me posted on what you find out, and if you have more questions, I'll be right here :)

      Hi Cathy,

      No concern here, when you use defrost the air conditioner is in operation which means it is removing moisture from the cabin air and draining it under the vehicle. Hope this helps :)

      Hi Eddie,

      I've today noticed a leak from under my car when I stopped in the garage. The fluid is clear and odourless, and seems to me to be water. With every drop there is a sizzling/popping sound coming from the area of the leak. The leak is coming from the middle of the car, about where the footwell would be. Is it likely to just be from the air conditioning system? It's about 90 degrees here today. Thanks for any help.

      Hi Wesley,

      If the vehicle drives normal, you're not losing coolant, and the oil level and condition are ok then I don't think you have an issue. Condensation builds up inside the exhaust system and mixes with soot for the combustion chamber which looks like black water and white steam or smoke will exit the tail pipe all the time but is more visible in cold weather conditions. I recommend driving it while keeping an eye on the temp gauge and fluid levels. Keep me posted on how you make out, thanks.

      Hi,

      I have just recently bought a brand new Kia Sportage, automatic. Barely driven it. However, I have noticed that after I reverse park the car, it leaves a fluid trail on the ground along the path that it was reversed on.

      Since I’m a new driver and this is my first car, it’s got me a little paranoid.

      Would appreciate your insight!

      Thanks.

      I've been told by a mechanic that I have a blown head gasket because white looking smoke is coming out of the exhaust pipe but I don't seem to be losing anti-freeze and the engine is not overheating. I think a blown head gasket would cause overheating and a lose of anti-freeze?

      Is this right of wrong? A block test didn't indicate liquid color change.

      Also, oil, transmission fluid or some type of dark liquid drips out of the exhaust.

      Hi Stephanie,

      It could be condensation leaking from a drain hole in the exhaust system. If the fluid is just water, most likely that is the culprit. This is normal, especially in very cold temperatures.

      Hi Hillary,

      Very low oil would cause this. You will need to put oil in the engine until you see it show on the dipstick. New oil is usually clear or amber in color, so check the dipstick carefully.

I had the car back maybe 2 or 3 weeks and the oil light came on so I added oil but even after I put oil in it when I check the dip stick it is not showing oil is in it. what would cause this?

I went out this morning and see a significant oil leak coming from the engine running all the way to the back right wheel ( lowest level I guess on my garage floor) where there is a puddle. I have no dipstick on this car. I’m thinking of just having it towed to a shop for investigation since I can’t tell how much oil is in the engine? Car is very low to the ground so not much is visible without putting it on a lift. I’ thinking about trying to get a low profile floor jack under it to make sure the drain plug and/ or oil filter has not loosened. Any other advice before I have it picked up?

      Hi Jamie,

      If it looked and felt like water, it was probably water. If you have dew on the vehicle in the morning, it can pool in areas of the vehicle and drain below the vehicle without a trace. Keep an eye on it for a few days and let me know if it keep happening.

      Hi Juan,

      I would not worry, there are a lot of reasons for water dripping. It can come from the AC evaporator even if you're not using the AC. It can also be coming from the exhaust system, a lot of condensation leaks from the exhaust. No worries, I believe this is normal.

      Hello,

      I have a new 2017 VW Jetta 1.8T. 90% of the times I put the car in reverse and reverse a little I see drops of water leaving a line of water on my driveway or any parking space. It even happens when the AC is off sometimes. I am concerned because it is a new car with only about 1500 miles on it so far and I would like to know if this is normal. I know for a fact it's water because I've touched it and put paper on it to see if it has a different color. I have never seen a car drip water almost every time it gets put in reverse.

      Hi Gary,

      If there are no leaks from the transmission, most likely the mechanic forgot to top off the trans or didn't fill it enough. One would think if you're replacing the clutch, the mechanic should spend a few more dollars and replace the transmission oil.

      I had a clutch replaced last spring, and recently I had an oil change, and the mechanic noticed my gear oil was quite low. Could that have been the result of the clutch work, and failing to top up oil level.

      Hi Alyssa,

      I recommend having the CV boots/axles checked for leaks, that would be the only thing that would leak thick black grease unless someone else parked there while you were gone. Once the vehicle is on the lift, the mechanic can check for any other leaks as well. Let me know what you find, thanks.
