M112 Block Drain
 

Have searched with no good results... I'm looking for the coolant drain on the M112 block (99 C280)... it appears to be on the driver's side, but I want to be sure exactly where it is before I start changing the coolant...anyone know exactly where this drain is located? Thanks in advance.

bump... can anyone lend a hand?? Thanks!

Bump again. Does anyone know?

I have two M112 engines, but I've never drained the coolant at the crankcase/engine. Attached is a photo from Alldata, but I'm having a difficult time figuring where the plug is on the engine by looking at the phto.

The block drain is a giant bleed nipple just like on a brake caliper.
It is on the left (driver's) side of the block directly above the motor
mount arm.
I think it is a 6mm allen inside to loosen.
DR.D

Thanks guys for your help, I hope to get it done this weekend.
