I have an 2001 Mercedes-Benz c240...What color should the coolant be that is used in this car. I paid to have it flushed but the coolant in it looks a greenish-brown color...is this right? Not sure they...
Hi. apparently the mechanic did not rinse the contents out completely after the flushing was administered. During the flushing of a radiator, there may be a good amount of debris that will build up, due to the flushing compounds effect on the crude inside the radiator. This is why there should be a rinsing stage to clean out all that is removed, via the flushing procedure. If the rinse is not done correctly, some of the contaminates will be left behind to mix in with the new radiator fluid. The rust/debris will mix contaminate the new fluid that is poured in, thus, causing the brown color you have noticed.
Most radiator fluids will be green, or orange in color, but never brown or greenish brown. This greenish brown will indicate that there is some rust deposited that were not rinsed out properly, after the flushing of the radiator. I would return the vehicle to the mechanic to request a re-flush of the radiator. They should do it for free.
NOTE_ A more serious issue will be a damaged oil cooler. this will cause the same symptoms within the color of the fluid, if your vehicle is equipped with this device. Once the oil cooler has ruptured, it will cause the engine oil to be transfer into the radiator, thus, changing the color of the fluid.
