The car is a 1997 C280. How do I tell if it has an oil cooler? If yes, where is it mounted? How does it look like?
Thanks

 

I don't think there is engine oil cooler. Antifreez cools the engine so the oil. Transmission has separate oil cooler.

 

Thanks. I bought a Bentley Service Manual, which states that there are two configurations for the C280 inline 6-cylinder engine, one with and one without an oil cooler. The manual shows schematics of the two but no pictures. I tried to trace all the connections out of the water pump and had concluded that my car does not have an oil cooler. Posted the thread to get a second opinion to be sure.
I am really a Saab driver and a DIY'er using the Saab Bentley Service Manual, which is outstanding. By comparison, the Mercedes Bentley Manual is a disappointment.
