[MBZ] How to force thermostat open
I am planning to flush and refill coolant in my W116. I have a new thermostat and would like to force the old one open to ensure that as much of the old coolant is removed as possible. What is the best way to force it into the open position (and hold it there)?

Re: [MBZ] How to force thermostat open
Not really necessary, as the coolant will disappear when you drain the block. Whilst the block and radiator are draining, change the thermostat. The M103 motor is a pain to change the coolant in, as it traps air up the top and there is a special plug at the top of the head to let the air out.

Re: [MBZ] How to force thermostat open
Unless I miss something, I would open any orfice in the biest, including T-stat housing, stick the garden hose in any end and flush. BTW that's how I found the culprit not having heat.

Re: [MBZ] How to force thermostat open
Ahhh now heres a debate we haven't had in a long time that'll get people riled up. Drilling holes in an MB thermostat won't do diddly. The thermostat works by closing one coolant passage while opening another. For some strange reason I don't completely understand the coolant won't flow through the radiator without the thermostat actually being open, if it doesn't close off that other passage it doesn't redirect flow. This is on 61x engines anyway, I haven't tried on 60x. Its true, try running a 61x without a thermostat, overheat city. Actually its stranger than that. From cold they'll usually run quite some time without a thermostat but if its warm and you shut it down and restart it'll overheat like crazy. I found this one out the hard way on my '81 300TD. -Curt Date: Tue, 30 Aug 2011 15:42:41 -0700 From: Alex Chamberlain apchamberl...@gmail.com To: Mercedes Discussion List mercedes@okiebenz.com Subject: Re: [MBZ] How to force thermostat open Message-ID: CABHyH=ZQdsr=j7dmxf+qwuh1cwagci6x7tgfo1pafs9n0jv...@mail.gmail.com Content-Type: text/plain; charset=ISO-8859-1 On Tue, Aug 30, 2011 at 2:54 PM, Allan Streib str...@cs.indiana.edu wrote: I am planning to flush and refill coolant in my W116. ?I have a new thermostat and would like to force the old one open to ensure that as much of the old coolant is removed as possible. ?What is the best way to force it into the open position (and hold it there)?

Correct. Bypassing the3 radiator when cool warms the engine faster - getting it up to operating temp as soon as possble, also providing cabin heat faster than most other cars, IMHO.
