Re: [MBZ] Coolant change Q
I have seen a lot of different types on MBs. also depends on if it is the original or a third party replacement. My '81 300TD had a little rubber/plastic plug thing, I think my '83 240D has a metal bung of some sort... -Curt Date: Mon, 31 Oct 2011 20:08:14 -0400 From: Allan Streib str...@cs.indiana.edu To: Mercedes Discussion List mercedes@okiebenz.com Subject: Re: [MBZ] Coolant change Q Message-ID: m1ty6oso0h@cs.indiana.edu Content-Type: text/plain; charset=us-ascii Dimitri Seretakis dsereta...@yahoo.com writes: Definitely pull the lower hose.

Re: [MBZ] Coolant change Q
Pull the lower hose. I need to change out the coolant in my 76 115 300D. I have been intending to do it ever since I bought the car and it has been waiting for me, patiently, I hope. On Saturday, I changed the oil. A lovely job on these old devils where one must crawl under instead of standing upright with one's $2 oil sucker. (As an aside, I bought a more expensive one - to do the oil on the boats, but have yet to try it out.) I put a wrench on the drain plug in the bottom of the radiator but it did not appear to want to budge. Any one think that it is safe to put an impact wrench on it? I wondered if a bit of impact might be safer than a long breaker bar. Not sure that penetrating oil will do much going upwards and not anxious to put heat on it given things are soldered together etc. What other options do I have?

Re: [MBZ] Coolant change Q
That is way too practical. Then I won't have cause to post more questions about how to repair the bung that I twisted out of my rad, or where the best place to buy a new rad is etc. I might have to try to start a new oil thread.

Re: [MBZ] Coolant change Q
I don't believe I've ever had a problem with an MB coolant drain in the radiator. Most W123s will have a plastic plug with a screwdriver slot and an o-ring seal, they don't need to be super tight and don't break. The one on the 280 SE is a standard winged plug sort of drain, but it wasn't stuck either. Later cars even provide a tube to slip some hose over to cleanly drain the coolant, it's easy as pie. Not so much on my buddy's Jeep -- have to pull the grille and headlight surround to get to the stinking drain plug, which I need to do soon as the thermostat housing gasket is leaking. Should have done it when I did the hoses, but I didn't know it was leaking at the time.
