Fluid Leaks Can Be Identified By the Fluid’s Color

The color of the fluid leaking out of your car, truck, or C/SUV helps us identify which fluid is leaking. The location of the leak can also be a telltale sign. For example, red fluid leaking underneath the center of your automobile is transmission fluid. Empire Auto Care is happy to repair your car’s fluid leak if you have one. We are also happy to flush and refill your automotive fluids when they need it. Let’s talk about the different hues of automotive fluids below.


The most common blue automotive fluid is windshield washing and de-icing solution. This fluid can leak out of the reservoir or the hoses that lead to the windshield sprayers. Your vehicle may also have antifreeze/coolant in it that is bluish-green.


You’ve got more than one brown fluid in your automobile. As you already know, the motor oil is brown. Your brake fluid may also be brown and the differential oil is brown. If your transmission fluid is old and dirty, it, too, will be brown to dark brown.


Water and fuel are the clear fluids in your automobile. Water drips off a running air conditioner compressor. It also drips out of the tailpipe due to condensation buildup inside the pipe. Smell clear fluid to make certain it doesn’t smell like fuel.


Many brands of antifreeze/coolant come in green, neon green, or green-blue. This fluid can drip out of the cooling system from numerous places, including the radiator, thermostat, water pump, and system hoses among other cooling system parts.


Your car’s antifreeze/coolant may also be orange. It could be that the original color of the fluid is orange, or that it has turned orange because it is filled with rust. The latter can occur in older vehicles that have corroded radiators with rusted-out bottoms.


There are a handful of red automotive fluids. As we mentioned in the introduction to this blog post, transmission fluid is red. Power steering fluid is also red. You might also have antifreeze/coolant or brake fluid that comes in a red hue.


Finally, antifreeze/coolant can also be yellow. In most cases, this pleasant hue is more yellow-green than yellow. It can also be neon yellow. Another fluid that looks as if it is yellow when it is new is brake fluid. It can also be amber or light brown.
