    Chlorinated compounds were fantastic solvents, but had environmental and personal impacts:(.

    Brakleen is now made in non-chlorinated form (use acetone as a base). But I used that on our egr cooler and it worked well;).

    Just not a potent(y).

    Ha ha yes, that wonderful 12 mm nut that almost take two people to R&R, one with long socket and swivel, and one with a magnet to guide socket. I reinstalled that nut on my first cooler job, this last one, that nut is still in my magnetic tray lol.

    After a good soak in super clean, or purple power, I plug end of cooler and spray PB blaster bolt loosening penetrating oil and fill cooler, that stuff melts the carbon to a runny goo. The piano wires a great idea, I used a large paper clip straitened out, finish with brake cleaner.

    I never had an issue with that nut, however I do wonder if the right hand drive set up makes it slightly easier to access that nut?
