Radiator Drain Screw Location on C280?
 

:confused: SOMEONE HELP!

I have easily located the red radiator drain plug on my C280 (1995), but I cannot locate the ELUSIVE engine block hex nut (apparently the second bleeding point.) I attempting to flush my radiator system.

Can anyone please help explain where I can find this screw? I can't flush my system without it.

Passenger side?

Apparently it is somewhere on the passenger side and can only be seen from under the car, which makes sense...
thanks,
mike

my c class is a four cylinder, but you may also want to try www.club202.com

the block drain plug looks something like a 13mm nut on a concentric threaded release valve.

I forgot, if you mess around on this site you'll find diagrams

Here you go. Number 38 is the drainplug.
