Mecedes calls for use of dilute citric acid to remove oil deposits from
cooling systems for their diesels. It requires follow up with a buffering
solution and thorough rinsing. It says repeat if necessary. This is a
procedure that will insure results. Like so many such procedures, it is
much easier to say than to do properly.
