Diagnosing leaks, is the first step, in determining, where and what needs to be fixed.
It may surprise you, but, diagnosing leaks, isn’t really that difficult.
In fact, the color of the leak or the smell it gives off, will usually point you in the right direction.
So, properly diagnosing leaks, can help you discover small problems, before they turn into a major repair bill.
In many modern vehicles, a warning light will appear, if certain fluids are running low. In other words, in some cases, it can indicate a leak.
Oil, coolant, and washer fluid, warning lights are common. So, if any of these lights come on, you should check the levels and refill them. While running out of washer fluid is normal. But, if the oil or coolant warning light comes on, you should have the system checked quickly.
Common Places To Check
So, we know what fuel smells like. But, it will look like water on the ground and may appear to be, colorful in direct sunlight. This indicates, an issue with the fuel pump, fuel injector or a leak in the fuel line or tank.
So, when diagnosing leaks, transmission problems are not great. And, a puddle of dark red or brown, is an issue with the transmission gasket, fluid lines or seals.
So, leaking power-steering fluid, has the smell of burnt marshmallows and is oily to the touch. The color is usually pink or red, sometimes brown if the fluid is old.
So, when diagnosing leaks, brake fluid leaks are bad and dangerous. Brake fluid, is usually clear or yellow, sometimes brown if it is old. It should feel oily to the touch. But, the big giveaway is its unmistakable, fishy smell.
The most common car leak color, is transparent or clear. Although, if you park on a dark surface such as a street, you may think it is something else. Fortunately, that fluid, isn’t a leak at all. Instead, what you have is water condensation, from the air conditioner. Reach down and touch the fluid and you’ll see, it is nothing but water.
Engine Oil Leaks
This leak should look black or brown and will feel thick and slippery, between your fingers. A slight acidic smell might also be a good indicator. Any of this under your vehicle, tells us there’s an issue with a oil leak. And may include, an oil filter seal, loose oil pan plug, leaking gasket and sometime a head gasket.
