Neil,

I use the blue steel brand tannic acid based latex emulsion type stuff. I think it is very similar to plastikote.

Great stuff but it doesn't stand up to heat very well. I doubt it will last on the coolant pipes. 

I'd wire brush the rust then use a phosphoric acid based rust banger then paint.
