I want to replace the antifreeze (its green and appears old) in my 87 190D 2.5 Turbo. Radiator appears to have two drain plugs with various little slots. How do you get these things out without breaking??? It does not appear to be the same type of slotted plug used in 300D.

 

yeah the drain plug you lookin for is in red and it will have a slot for flat blade screw drive to fit in,anti clock wise to open turn,dont fill any cheap coolant get the best one from MB it about £22.00 for 5lts you need to fill all 5 lts and top up with normall water if you need to.............
