4 Common Causes of Leaks Coming from Your Car – Our Guide

So, you’ve discovered a leak beneath your car and are now scrambling to try and figure out what it is and whether or not it’s a serious matter. What’s worrisome about this is that leaks can be negligible or serious enough to warrant a visit to the nearest mechanic shop. This all depends on where the leak is coming from.

To help you figure this out, we’ve compiled a list of the four common causes of leaks and how you can identify them:

Coolant Leak

Coolant leaks are by far one of the most common types of leaks. It’s also one of the most easily identifiable leaks, thanks to the coolant’s distinct color. Depending on what type you use, they can be green, pink, and even orange. If the color doesn’t give it away, the texture of the liquid is also rather unique.

Coolant is slimy and thick. The smell is also a dead giveaway, as coolant gives off a sickly sweet smell that can even smell like candy. Despite the odor, the coolant is extremely toxic and should be kept away from pets and small children. Coolant leaks don’t necessarily warrant immediate repairs, but you shouldn’t neglect them for too long as this type of leak makes it more likely for your car to overheat.

Fuel Leak

If you have the gas station smell following you around wherever you go, then it’s likely that your car has a fuel leak. This is confirmed if you ever spot a black or brownish puddle under your car. You should seek immediate professional help in case of a fuel leak. We recommend seeking a mobile car repair service as driving a car with a fuel leak can cause a fire in your car!

Oil Leak

Oil leaks are rather easy to spot due to their unique texture. If you find a slippery liquid under your car, then it’s most likely an oil leak. The color of the liquid will vastly differ depending on how well maintained your vehicle is. If you’ve just had the oil changed, the motor oil will be closer to an amber color. If it’s been a while since you’ve taken your car in for a change, then the oil will be darker in color. Motor oil is incredibly important when it comes to keeping your car in good condition. If you’ve spotted a leak, go straight to your trusted mechanic to have it repaired.

Transmission Fluid Leak

If you find a pink or red puddle under your car, then it’s most likely a transmission fluid leak. This fluid will be thick and oily, which is why you can easily mistake it for coolant. Unlike coolant, transmission fluid won’t smell sweet at all. It is what’s responsible for keeping your vehicle’s transmission lubricated to ensure that the gear shifts are smooth. A tell-tale sign of a transmission fluid leak is difficulties in shifting to higher gears while driving. You’ll want to get this repaired as soon as possible as failing to do so can potentially permanently damage your vehicle’s transmission!


We hope this article has helped shed some light on the reasons for car leaks. Spotting leaks early and determining where they’re coming from is the key to keeping your car in good condition. If you spot any complications, be sure to take your car to the nearest mechanic shop as soon as possible to remedy the issue!
