Nate – you can also use straight white vinegar to cleanse the system. Most of the crap that is sold
for cooling system cleaner is weak.
The best I've used is Thoro Flush: http://www.irontite.com/aws_vid.html
Used it and the vinegar in my 49 Ford flathead cooling system and was surprised at all the junk that
came out when I back flushed the system.
Now, with all that crud floating around in the cooling system, the radiator could get full of stuff
and need to be 'rodded out'. Where the two caps are taken off and a rod is used to clean out each
tube in the radiator core.
Back flushing is a big deal too, as it pushes most of the crud out of the radiator.
Need to get agro with it. Once squeaky clean, add coolant and one bottle of water wetter.

Subject: [diesel_mercedes] 240D Top Speed ?

So ;
In trying to fully clean the cooling system I have taken to running this car (1982 240D automatic Sedan, 358,000 + miles, bad valve in # 1 cylinder) with the throttle pinned and the heater turned to max hot (fan off) on the freeway when I can find it open .
After a couple miles the temperature begins to creep up and almost reaches 100* C ~ at this point whatever silt or crud is in the wee corners of the water jacket begins to break loose and mix with the distilled water I'm running .
After a 15 minute run yesterday the water remained clear so I *thought* I was all done and ready to install pre mixed coolant but after tearing up the Harbor freeway @ full tilt boogie this morning I popped the radiator cap to find foamy stuff, meaning there's still a little bit of cleaner or something in there ~
This afternoon I drained it (block and radiator) and refilled it with distilled water and hit the I-1210 freeway , pinned the throttle and waited .
Much to my surprise it easily pinned the speedometer (@ 82 per GPS) and continued to accelerate ~ this was on a slight down hill grade and eventually I guess it hit the governor in the injection pump as it flat wouldn't go faster than 89 MPH .
That's plenty fast for a 50 HP 4 cylinder naturally aspirated Diesel pushing a 4,700 pound car through a slushbox tranny .
I also eyballed the toe in , I'd noticed the car " hunting " a little bit and it was toed out .
Now it drives O.K. but the steering wheel is slightly off set to the right so I must needs re adjust the tire rods to center it .
