Is there more to it where they tell you not to restart a warm 61x engine with the thermostat removed or something? I hate to revive a really old argument (like from my first days on the list 9 or so years ago) but you can't run a 61x engine any amount of time with the thermostat removed or the car will overheat. Double action thermostat and all that.
The interesting thing I found was that I could get maybe a half hour of driving if I started with a cold engine and went but if the engine was warm and restarted it would overheat quickly... -Curt Date: Mon, 26 Nov 2012 13:48:04 -0600 From: Rick Knoble <rickkno...@hotmail.com> To: Mercedes Discussion List <mercedes@okiebenz.com> Subject: Re: [MBZ] Cooling System Flush Message-ID: <bay403-eas128e002630293905068b805dd...@phx.gbl> Content-Type: text/plain; charset="us-ascii" On Nov 25, 2012, at 8:44 PM, "Alex Chamberlain" <apchamberl...@gmail.com> wrote: > > Where does the special tool, aka thermostat modified with shell casing, > come into it? With OM61x engines it doesn't. According to the TFM in PDF 20-015 page 1 heading A sub 2 "remove coolant thermostat (20-110)". With OM60x engines it does. In the same number PDF for OM602 (w124) on page 1 under Coolant thermostat it says "remove and install forcibly-opened thermostat part no. 000 589 74 63 00 (step 1) I may be presumptuous, but I assume the engineers at MB know way more about this stuff than I do. I included reference material, so no one thinks I pulled these facts from thin air.
