I just purchased a 1988 300E and have a lot of questions and some problems with the vehicle I hope someone can help me with.


Power steering:

What kind of fluid should I use and how full should I fill the reservoir, I have not found any full markings? How much fluid should I buy if I am going to replace the filter?

You can use any dedicated power steering fluid. I bought two quarts because I wanted to flush the system using the turkey baster and dilute method. Normaly there is a level mark on the plastic spacer on the threaded rod that holds the cap. Sometimes there is a line on the insider of the reservoir body. In my case I had markings on neither so I filled it to halfway up the plastic spacer. Good so far.


Is the motor a M103 and how do I find the body style?

Yes the motor is an M103, the body is a W124.
