Real Causes of Water Leaking From Under A Car
Some of the most common causes of a water leak are the exhaust, the cooling system, and the windscreen washer system. If you see a clear and odorless fluid under your car, then it’s possibly just water from your car’s AC system. The air conditioning system of your car is the most common source of water leaks.
Depending on the temperature, it might happen that the moisture from the air concentrates on the AC parts and then dribbles down close to the rear of the engine section. To avoid such a situation, turn on its recirculation switch rather than placing it in the fresh air option.
If you see water running in the cabin, it could be because the water is condensing and flowing out of the car through the indoor unit water pipe, This is because the hose has been blocked by dirt or debris. Therefore, you need to unclog the indoor unit pipe as soon as possible.

So, if you see a little water popping out of your tailpipe, there is no need to worry. Just check out the coolant level and if it’s not low, then you are fine. On the other hand, if you suspect that the leak is from the windscreen washer system, you can simply ignore it without any tension.
If there is a large puddle of water under the vehicle, you need to check the rubber hoses of the cooling system. Next, check the amount of cooling water in the tank is not much, if it is low, add more cooling fluid.
