I am using the ALLDATADIY on-line manual for my car since I can't get it anywhere else. I have an oil leak that looks like it is coming from the oil cooler lines. It appears that the oil cooler in the service manual is mounted near the oil filter toward the rear of the engine on the driver's side, however, this cooler is a separate smaller cooler that is mounted in front of the radiator, near the bottom. I am confident that the leaks are oil, however, in hitting "the BenzBin" for parts, the lines look like the lines that are designated for the transmission cooling. </P>


Does Merc route the cooling <U>through</U> the radiator, or is the transmission cooler a separate cooler? The leaking fluid is not red in color, otherwise I would have suspected the transmission lines to start with. The lines I am looking at have an external spring steel wrapping at the end where the hose is mounted on the fitting. Any advice would be appreciated....</P>

 

those lines are your transmission cooler lines and yes the ATF cooler is located in the radiator. As ATF gets older itwill not be the bright red you may be accustomed to seeing, so after you replace the leaking hose you may want to consider an ATF fluid and filter change.
