Bleeding coolant system on a W126 - 560SEL
 

can someone describe how to Bleed the coolant system of a 560SEL? There is a plug on top of the intake, rear driver's side, next to the heater hose. It appears like a bleeder plug as it could be the highest point of the coolant system.

thx

The system is self-bleeding. The little hose that goes to the top of the radiator & over to the expansion reservoir is the way air gets to the highest point of the system.
