I've had the rad out after a little incident in Mexico last year, it is fairly straight forward. As far as accessing the muff from there, next to impossible 'cause of limited access. I'll take a look throught the access panel then.
I'll PM you with my e-mail address, would appreciate the pics and info. What division is your son in at Everett? 60 of us from Air Canada took a tour of the triple 7 and 787 last year. My confidence in Boeing equipment increased from high to very high after meeting the guys down there. Nothing like American know how when it comes to building airplanes!! Like they say..."Airbuses are built by stupid people for smart people to fly, Boeings are designed and built by smart people for stupid people to fly."
