S 500 Coupe (140.070) V8-5.0L (119.980) (1997)
Power Steering Line/Hose: Description and Operation
Standard Pump
NOTE: Numbers in parentheses ( ) indicate a component or tool in the associated illustration.
The pump housing has a pressure connection on which the pressure line (29) is connected to the power steering. The return line (28) from the power
steering is secured to the return connection
Vehicles with a high front axle load need high pump pressures and flow rates but this causes pronounced heating up of the steering gear oil
In these cases a servo oil cooler with bypass is also built into the return line.
