These days, coolant (also known as antifreeze) comes in a rainbow of different colors. But older vehicles use inorganic additive technology coolant (IAT) that&rsquo;s almost always green.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your car can develop <a href=\"https:\/\/www.carparts.com\/blog\/coolant-leak-symptoms-plus-faq\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"coolant leaks\">coolant leaks<\/a> from many different places. Common sources include the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Radiator<\/li><li>Heater and <a href=\"https:\/\/www.carparts.com\/blog\/radiator-hose-problems-6-symptoms-of-a-bad-or-failing-radiator-hose\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"radiator hoses\">radiator hoses<\/a><\/li><li>Water pump<\/li><li><a href=\"https:\/\/www.carparts.com\/blog\/thermostat-housing-leak-causes-replacement-cost-symptoms\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Thermostat housing\">Thermostat housing<\/a><\/li><li>Freeze plugs<\/li><li>Head gasket\/s<\/li><li>Heater core<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes, you can easily pinpoint a coolant leak with a quick visual inspection. If that doesn&rsquo;t work, either you (or your mechanic) can pressurize the system using a special tool. Once the cooling system is under pressure, the coolant should begin to drip (or pour) out of the leak, making it easier to spot. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\">A\/C Refrigerant Dye<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Although air conditioning (A\/C) refrigerant itself is colorless, it often contains green trace dye that&rsquo;s added for diagnostic purposes. Unlike coolant, the green dye has a neon hue to it. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Refrigerant leaks can develop from almost anywhere in the A\/C system. Common locations include the following: <\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Compressor<\/li><li>Condenser<\/li><li>Evaporator core (you may see dye leaking out of the drain)<\/li><li>Lines and fittings<\/li><li>Pressure switch<\/li><li>Expansion valve or orifice tube<\/li><li>Receiver\/drier or accumulator  <\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Usually, the dye will cling to the source of the refrigerant leak, making it easy to pinpoint. You can use an A\/C leak detection kit (UV light and goggles) to get a better view if necessary. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To fix the leak, a professional will first need to use a dedicated machine to recover the refrigerant. Otherwise, when the system is opened for repair, any remaining refrigerant will escape into the atmosphere&mdash;and allowing that to happen is illegal. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once the refrigerant is recovered, the leaking component can be replaced. A professional will need to evacuate and recharge the A\/C system after the repair is complete. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Automatic Transmission Fluid<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Although most cars use automatic transmission fluid (ATF) that&rsquo;s red in color, some vehicles that have a continuously variable automatic transmission (CVT) use green ATF. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ATF is oily to the touch, whereas coolant feels slippery.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As you might guess, ATF leaks can stem from a variety of locations. Here are some of the most common sources:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/www.carparts.com\/blog\/transmission-gasket-replacement-cost-location-and-faq\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Transmission pan gasket\">Transmission pan gasket<\/a><\/li><li>Output shaft seals or axle seals<\/li><li>Cooler lines and fittings <\/li><li>Torque converter (front pump) seal <\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Typically, you can pinpoint an ATF leak with a simple visual inspection, or you can have a professional do the job for you. Once you know where the leak is coming from, you can move forward with replacing the offending component. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Honey-Colored or Semi-Transparent Fluid<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/honey-colored-fluid-1024x683.jpeg\" alt=\"engine oil being poured\" class=\"wp-image-17734\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/honey-colored-fluid-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/honey-colored-fluid-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/honey-colored-fluid-768x512.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/honey-colored-fluid-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/honey-colored-fluid-150x100.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/honey-colored-fluid.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Engine oil is usually honey-colored or semi-transparent when fresh and clean.<\/figcaption><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Engine Oil<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Several different fluids are honey-colored or semi-transparent when they&rsquo;re fresh and clean. Engine oil is one of them. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your <a href=\"https:\/\/www.carparts.com\/blog\/why-is-my-car-leaking-oil\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"car is leaking engine oil\">car is leaking engine oil<\/a>, here are some of the most common locations where it could be coming from:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Oil pan gasket<\/li><li>Valve cover gasket\/s<\/li><li>Crankshaft seal <\/li><li>Camshaft seal\/s<\/li><li>Oil filter <\/li><li>Oil filter adapter housing gasket<\/li><li>Drain plug <\/li><li>Timing cover gasket or sealant<\/li><li>Oil cooler lines <\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Some oil leaks can be found through a simple visual inspection. In other instances, an oil leak will become a huge mess that&rsquo;s all over the engine. And when that happens, it&rsquo;s a good idea to clean the engine off thoroughly. Then, run the vehicle to verify the location of the leak.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once you know where the leak is coming from, you can replace the necessary components to repair the problem. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Gear Oil<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Gear oil, which is used in many differentials, transfer cases, and manual transmissions, starts out honey-colored or semi-transparent. You&rsquo;ll usually find gear oil leaking from one or more of the following locations: <\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Differential cover gasket<\/li><li>Output shaft seals<\/li><li>Axle seals <\/li><li>Case half gasket <\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Usually, you can spot a gear oil leak by safely raising the vehicle, then taking a peek underneath. Fixing the problem involves replacing whatever component is no longer sealing properly. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Fuel<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Gasoline and diesel fuel are semi-transparent. Fuel is easy to recognize because it has a distinct odor. If you see or smell fuel, it&rsquo;s likely coming from one of the following locations:  <\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Fuel lines<\/li><li>Fuel filter <\/li><li>Injector or injector o-ring <\/li><li>Gas tank <\/li><li>Diesel high-pressure fuel pump or transfer pump <\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Fixing a fuel leak involves first pinpointing the leak, then taking the necessary actions to repair the problem. The fix could be anything from a simple fuel filter swap to replacing the entire gas tank. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Brake Fluid<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Fresh brake fluid is honey-colored or semi-transparent. In most cases, a car that&rsquo;s leaking <a href=\"https:\/\/www.carparts.com\/blog\/low-brake-fluid-symptoms-plus-when-to-change-and-faq\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"brake fluid\">brake fluid<\/a> will have reduced stopping ability, making it unsafe to drive. You should have the vehicle towed in for repair if you find a leak from the brake hydraulic system. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here are some of the most common locations for a brake fluid leak: <\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Master cylinder<\/li><li>Hydraulic valves <\/li><li>Brake lines<\/li><li>Calipers<\/li><li>Wheel cylinders <\/li><li>Clutch master and slave cylinder (manual transmission-equipped vehicles)<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It&rsquo;s usually pretty easy to identify the location of a brake fluid leak. Depending on your skill level, you can choose to either fix the leak yourself or have a professional tackle the job for you.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One thing to keep in mind is that you&rsquo;ll need to bleed the brake system (unless you&rsquo;re working on the clutch hydraulics) after the repairs are complete. Failing to do so will result in little to no braking ability when you go to drive the vehicle. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Power Steering Fluid<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Power steering fluid can also be honey-colored or semi-transparent, though some vehicles use red automatic transmission fluid instead of dedicated power steering fluid (more about that below). <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A power steering leak usually stems from one or more of the following locations:  <\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Power steering pump<\/li><li>Steering gear <\/li><li>Lines <\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Typically, all you need is a flashlight and good eyesight to spot the source of a power steering leak. You can then either fix the problem yourself (if you have the know-how) or have a professional do the job. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The power steering system will need to be bled of air after the repairs are complete. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Red Fluid<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/red-fluid-1024x683.jpeg\" alt=\"red ATF fluid being poured into car\" class=\"wp-image-17733\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/red-fluid-1024x683.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/red-fluid-300x200.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/red-fluid-768x512.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/red-fluid-600x400.jpeg 600w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/red-fluid-150x100.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/red-fluid.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Automatic transmissions use red-colored ATF.<\/figcaption><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Automatic Transmission Fluid<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Automatic transmissions (and many transfer cases) use red-colored ATF. In some instances, a car&rsquo;s power steering system may also rely on ATF. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Coolant<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Most automakers have begun using organic additive technology (OAT) or hybrid organic additive technology (HOAT) coolant.

Nearly all varieties of washer fluid (except for a few blends) are blue in color. Washer fluid leaks almost always come from one of the following locations: <\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Washer reservoir<\/li><li>Lines<\/li><li>Nozzles <\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If you&rsquo;ve been considering taking up DIY auto repair, fixing a washer leak is a good first project. In most cases, the job is easy to do. Plus, there&rsquo;s very little risk of damaging other parts of the vehicle during the process. <\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Coolant<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">A variety of automakers&mdash;including Subaru, Honda, Mazda, etc.&mdash;use blue coolant in select models. Some other vehicle manufacturers (e.g., BMW and Volvo) use HOAT coolant with more of a turquoise hue. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Purple Fluid <\/h3>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/purple-fluid-1024x429.jpeg\" alt=\"purple fluid being poured into car\" class=\"wp-image-17729\" width=\"1024\" height=\"429\" srcset=\"https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/purple-fluid-1024x429.jpeg 1024w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/purple-fluid-300x126.jpeg 300w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/purple-fluid-768x322.jpeg 768w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/purple-fluid-150x63.jpeg 150w, https:\/\/www.carparts.com\/blog\/wp-content\/uploads\/2019\/05\/purple-fluid.jpeg 1500w\" sizes=\"(max-width: 1024px) 100vw, 1024px\"><figcaption>Purple HOAT coolant is found in various vehicles, including certain models from Mercedes-Benz, Audi, VW, Porsche, and others.<\/figcaption><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Coolant <\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Nowadays, <a href=\"https:\/\/www.carparts.com\/blog\/radiator-fluid-color\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"coolant comes in a myriad of color\">coolant comes in a myriad of color<\/a>s&mdash;including purple.

Most of the fluids that start out honey-colored or semi-transparent (i.e., engine oil, gear oil, etc.) turn brown over time. ATF also eventually becomes brown from use, as do most types of coolant. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But in most cases, brown fluid is dirty engine oil. Take a peek under the hood and, if necessary, underneath the vehicle. If the fluid is clinging to (or dripping from) the engine, it&rsquo;s probably engine oil. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Watch these videos for tips on how to check your fluid levels:<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"How to Check the Fluid levels 2009-2014 Ford F150 &#128738;\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/yeu72hrxTsI?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"How to Check the Fluid levels 2009-2018 Dodge RAM 1500 &#128738;\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/uvmXc96KA4I?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<h1 class=\"wp-block-heading\">Where to Find Replacement Parts to Fix Fluid Leaks<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Fluid leaks can point to various car problems, and disregarding them can lead to expensive repairs.
