I did this today. Wow, I have read the many discussions about how much crap can accumulate in the scoops and between the radiators, but I truly was not prepared for the amount of dirt, leaves, and grass I found in between the radiators, simply astonishing!
I also followed the excellent write up linked in the first post. I was having difficulty separating the two radiators, and almost did not bother, I was really worried about bending the aluminum pipes. Glad I did though, wow.
Also too the opportunity to repaint the inlet grills,, decided to split the difference between black and silver, had some dark metallic gray left over from a set of wheels I painted. It was too dark to get a good pic of that today. But I like it
