Folks, Seems the subject motor was actually an OM 617 engine so the link now points to the instructions for that engine (5 cyl iron head OM): http://pt709.synology.me/20-015.pdf
In case anyone wants the writeup for the 616 engine, it's here: http://pt709.synology.me/20-015-616.pdf Scott -----Original Message----- From: Mercedes [mailto:mercedes-boun...@okiebenz.com] On Behalf Of Rick Knoble Sent: Sunday, June 02, 2013 9:38 PM To: Mercedes Discussion List Subject: Re: [MBZ] Citric Acid Flushing > On Jun 1, 2013, at 10:28 PM, "Hendrik and fay" <heni...@gmail.com> wrote: > >> From memory you need a thermostat to seal the housing? > Then Rick wrote: > OM60x yes a forced open thermostat is required, OM61x no thermostat required to flush system.
