560 maintenance
 

What are the proper time intervals are for fluid flushes (hydraulics, coolant, steering, etc.)? every year? 2 years? or is it more based on mileage?

Most of us try for changing brake fluid every 2 years and coolant at least every 3 years and use MB coolant. I do the power steering fluid and filter every 2 years also. Oil and filter every 3,000 miles or every 3 months if you don't run up the milage that much.

janos,
every 30000 miles for fluids is the service manual recommendation for the w126's I would recommend 30000 or two years for the fluids (radiator, tranny, diff and brake fluid)
Oil they say every 7500 but I would recommend at least 5000 miles.

I don't know what the fluid change interval (if any at all) for the Hydraulic self-leveling suspension.

The fluid change interval required by Mercedes Benz for the Brake Fluid and Radiator coolant is as follows:

1. every two years for the brake fluid.

2. every three years for the radiator coolant.
