C240 4MATIC (2004)
![Unhappy](https://mbworld.org/forums/images/icons/icon9.gif)
I currently own a C240 4MATIC (2003 Model). I notice that my radiator reservoir has some oily and brownish residue in it. I took it to the shop and was told it was the oil cooler and spent a reasonable amount 'fixing' it. Just 6 hours later and the same is back. I really need help here. Also new to this forum.

Oily Residue in Radiator Reservoir
Its the engine oil cooler well it was either a faulty one or the issue is with the transmission radiator most of the times people misdiagnose the color of the oil , but in your case i believe its the transmission oil cooler which is the radiator , i advise you to not move the car and get it fixed as soon as possible. Also double check the mechanic did a full flashing for the system cause that oil you saw after 6 hours could be the residue still in the engine .

Is that photo for real? That looks like someone puked all over the reservoir. ![EEK!](https://mbworld.org/forums/images/smilies/eek.gif)
Did you check to see which radiator (Valeo = bad, Behr = good) was installed in your car?
As the others have mentioned, stop driving the car immediately, before you trash the transmission.

Well, am certainly a happy guy now. It turned out to be the Oil Cooler. They replace it with a used one and only made it worse. It started leaking water into the engine oil. I had it drained and a different cooler installed. Its been 4 days now and my car is purring nicely. Thanks for the comments and guidance. You guys rock!!
