Re: [MBZ] Citric acid flush
You can still get powder detergent, at least my local Target carries it, I know because I recently bought a box of Tide powder to try it on some grease-stained shirts. It seems to me that it does a better job on grease stains than the liquid detergent. I now use it for kitchen towels and any clothing with grease spots.

Re: [MBZ] Citric acid flush
As Jaime mentioned, laundry detergent is best. And I recall when this was a topic during Dr. Booth's presence on this list, a key point was to seek out so-called "HE" (high efficiency) detergent intended for front-loading washers. It is the least "foamy". Not sure if that still matters, with the current ubiquity of front-loaders in the US. I can't see why it would need to be powder. The key point is that it circulate and clean. I would think it would be important to RINSE very thoroughly. AND DON'T FORGET TO CHANGE YOUR FUSES!

Re: [MBZ] Citric acid flush
I went to the local hardware store and the guy there said they used to have it, for cleaning water softeners. But he couldn’t find any so I ordered a 5lb bag from Bozos. It will be interesting to see what it does. I put some dishwasher detergent in and warmed the engine and drove it a bit. Temp is kinda bouncing around 80-100C, I noticed the electric fans are not kicking on so will need to see what that’s about. I was thinking maybe the thermostat but that’s probably ok. I also noticed that the overflow fitting on top of the radiator was spewing, a little plastic elbow held on with metal tabs that fits into a hole in the top of the radiator. The metal tabs are loose. What a POS design. I guess that’s where the coolant was going, aside from the failing radiator hose. I’ll have to see what that’s about too.

Yes, you need to de-oil the system first. Laundry detergent is good since it doesn’t bubble up much.

Re: [MBZ] Citric Acid Flush
Hi Scott - Thanks for providing this. In expectation of doing this I tried to find a similar pdf for the W124 602 engine. Didn't see this comment from the MB pdf on the de-oiling pdf you provided, but I found this on the 602/603 Instructions 20-0160 saying: *Note:** **The Oil in the cooling system has to be removed** **if, for example, engine oil, ATF on models with** **automatic transmissions or hydraulic fluid has got** **into the cooling system.** * Which makes sense IMO . - the pdf you provided did not have this note and I don't know about anyone else but I for one thought it meant de-oiling needed to be done as standard maintenance.. Anyway - FYI ya'll...;-) BTW, with the comments in this thread about removing large amounts of rust from some cooling systems, seems like a little oil might not be a terrible idea? unless it reacts somehow with the coolant?

Re: [MBZ] Citric acid flush - was: Heat wave
Jaime Kopchinski wrote: The method in the manual really works... when you remove the thermostat, you get lots of flow and lots of stuff clears up. Just for reference, since there are a lot of OM616 and OM617 motors on the list, removing the thermostat is NOT a good plan. I don't remember the M117 so it may be a single throw - but the diesels are a double throw design. That is, when the path to the radiator opens, the bypass is closed. Simply removing the thermostat will leave both open and will NOT WORK correctly. For these, you must use a modified thermostat that is jammed open.

Re: [MBZ] Citric acid flush - was: Heat wave
While its true that you should never run one of these engines without a thermostat under normal use, its part of the standard procedure when cleaning the cooling system for both early M116/M117 and OM617 engines. See Job 20-015 of the OM617 manual for example: http://www.startekinfo.com/StarTek/outside/12265/disc_2/program/Engine/617/20-015.pdf Job 20-015 from the M117 manual: http://www.startekinfo.com/StarTek/outside/11883/PROGRAM/Engine/107/M117_45/20-015.pdf I have seen this special open thermostat mentioned in manuals also, but I can't recall for which models... perhaps only newer cars? It could be necessary because sealing of the termostat house isn't possible without something taking up the space in some engines?

I am sure I saw it in my paper manual for W123s, but 20-015 does say to remove the thermostat. I looked briefly in the manual and did not see anything about the forced-open thermostat. Hmmm It could be necessary because sealing of the termostat house isn't possible without something taking up the space in some engines? They all work by having the disk on the end of the thermostat move and block off the flow directly to the block, forcing it to the radiator.

The laws of hydrodynamics indicate that the path of least resistance will get the most flow. And the path through the engine is going to have a higher resistance than the 6 inch bypass pipe. Therefore most of the water will not go through the engine if the bypass isn't closed. Do whatever you want - but when I do a cooling system flush, I want it all cleaned out.

1 kg citric acid in 5 liters of water from the 602-603 manual. More exactly, 1kg per car, dissolved into about 5l before you pour it in. You'll make up the balance with water. I just used half the 5# container I bought. -- Jim
