OM617 turbo

Previous owners did not maintain the cooling system. Hoses have thick layer of rust and scale built up on all surfaces. I am certain the block is just as bad if not worse.

Occasional high running temps, but not severe.


I have tried typical acid flushes - they're just not cutting it.

Looking into products like this (evaporust):

Evapo-Rust Cooling System Cleaner



Any one used anything like this? Any opinions?


I am not concerned about the radiator, or if it clogs.
