I need urgent advice to correctly flush oil contamination from my 2001 BMW 530d cooling system. I have thus far been told to use a quality de-greaser and flush the system..several times if necessary.
I have removed the compression tank to remove most of the gunk that has suddenly accumulated. Replaced same.
Can I add de-greaser straight to cooling system via coolant intake?
What then..?
I really need to know step by step.
