Re: [MBZ] Cleaning the cooling system
Thx Jim - I read the procedure 20-015 you mentioned and it was very easy to follow except for a comment saying to replace the coolant overflow tank with one containing Silica Element - for my 602-96X Turbo that means pn 124 500 18 40. But I didn't see any reason for *why* the coolant exp tk needs to be replaced. Any ideas? Also - why the Silica Element? I thought Silica was the stuff that removes moisture from packaged electronics and such. Thx - LarryT '91 300D OilAnalysis Time?

Re: [MBZ] Cleaning the cooling system
If you're mixing oil and coolant, you probably don't want to get detergent in the oil system. Also, you don't want to flush it out with soap and water before taking it apart if freezing is a possibility. I'd fix it first, then flush the oil out of the cooling system, then change the oil and replace the coolant.

Re: [MBZ] Cleaning the cooling system
you don't want to flush it out with soap and water before taking it apart if freezing is a possibility. This is a good use of the block heater, if you can't get it all done in one session (cleaning, flushing, new coolant). The heater will keep it from freezing 'til your next session.

I'm thinking that Mother Benz specifies a citric acid douche.
Back in the day, I use plain water with a few ounces of TSP {AKA Spic

Re: [MBZ] Cleaning the cooling system
Last I remember, the sequence was to remove the oil with a detergent type
cleaner (the Prestone kits at the FLAPS), followed with the citric acid
flush to remove the scale/calcium deposits. Since it's leaking now, I'd do
all this after re-assembly.

You don't want grit, either. Washing machine soap of some sort

[MBZ] Cleaning the cooling system
We have a plan Looks like the head gasket replace on the 2.6 190e is going to happen next weekend (Dec 4). With a cooling system that is well oiled, what is the list wisdom regarding cooling system cleaning? Before or after the replace? Suggested products? (With as much oil as there is in this system, Tide might be a good choice.) I live where it hard freezes at night, so I think I'm either going to need some thing that works with coolant or I'm going to need something that works right now. BTW, dau #2 effing loves the car. Thanks in advance.
