What is this fluid leaking from my car?

Is the leak from your car a cause for concern? In order to answer this question, first of all, double-check beneath your car to see if there are any traces of leakage to determine if the leak is actually coming from your vehicle. The next step is to figure out where the leak is coming from and what's leaking. The simplest method to accomplish this is to place a piece of white cardboard below the car while it is parked to catch the drips. Your car may be leaking oil, water, coolant, gas or a different fluid altogether.

Common conclusions

Your vehicle is leaking engine coolant. If the leak is severe, your radiator might be punctured or cracked. You need to bring your car to the mechanic as soon as you can, or else your car will overheat, which might damage the engine.

Your car is leaking gasoline. The leak might be coming from a loose hose attached to your fuel pump. Locate the leaking hose, tighten the hose clamp, and the leak should go away.

You are leaking gasoline. Your gasoline tank might have a hole. There are DIY kits that you can use to patch up leaking gas tanks, but just to be on the safe side, bring your car to the garage.

Your car is leaking engine oil. If the leak is not that much, like a couple of drops or so, the oil pan plug might be loose, but if there is a huge pool of oil under your car then there is a broken oil seal in your engine. Top up the oil, and bring your car over to the garage for repairs. If your car continues to leak oil, it will cause serious damage to your engine parts.

Your car is leaking brake fluid. Do not attempt to drive your car to the mechanic, instead, get it towed over there. Driving with insufficient brake fluid can cause your brakes to fail and cause a serious accident. Even if you just suspect that your car is leaking brake fluid, be on the side of safety and just have your vehicle towed.

Your car is leaking automatic transmission fluid. Although it is not necessary to have this problem fixed, you should at least get it fixed as soon as your schedule allows, but do not ignore this problem for too long. The automatic transmission fluid is responsible for the smooth shifting of the gears when your car is running, if your transmission gets seriously damaged because it ran out of fluid then you’re looking at almost $2,000 in repairs.

The container for the windshield washer solvent might have a leak, or one of the hoses might be loose. This is not really a serious problem, in fact, you can ignore it altogether if you do not use the windshield washer that much anyway.

That's just plain water, and no, you should not worry about it. When water starts dripping from underneath your car after a rather long drive on a hot day, it’s just from the condensation that formed in your car’s air conditioning system, specifically the condenser.
