Hello All
I am the satisfied owner of 96' E420. It drives good and I want to keep it. However it has a serious problem inside cooling system. The car now runs with third radiator and it is clogged again. Please review the image of inside radiator white non-hard deposits, it gets easily crushed with fingers. I believe this junk comes from engine block. Previous owner said that car was still for about a year. perhaps it is spoiled coolant leftover.. I have flushed it several times with distilled water. Recently after putting in new coolant the radiator starts to get clogged again. Engine is hot and most parts of radiator are not hot...

I will take any suggestion, any liquid, any acid just to clean it out. Thanks!
