Re-Fit Radiator

Assuming your cold water pressure is reasonable, connect a hosepipe to each port (alternately, and several times), and give it a good blasting until the emerging water is clear?

Thinking about it further, I believe that various 'colas' contain phosphoric acid - the active ingredient in de-rusting materials like 'Kurerust'. They can be used to remove surface contamination and corrosion from metals. You might like to experiment with a piece of rusty metal.

If it works, to really get rid of all the internal surface rust, you could try filling the radiator with a bottle of cola. Make sure you use the 'Real Thing'! ;o))

Plug one end, stand on that end, fill with cheap cola and leave for a weekend, the phosphoric acid in it will dissolve the rust and passivate the inside surface with iron phosphate in its place? Then rinse until the kids can't drink any more... ;)

Sounds interesting, but what effect/reaction does any residual Cola or iron phosphate have with system inhibitors etc.?
