Watch the videos ! Have a piece of carpet to lay the cover on. A very rewarding exercise. When I had to change a rad fan later in life it made me fearless in going after that task. I too installed grills after seeing the size of the debris in my radiators. Don't use crowbars or torches it will all come undone readily. You will appreciate the engineering/design of your machine. We need all the cooling we can get in Fla. My AC worked measurably better when done.
I think I will get a radar detector for fathers day. If they have been getting my hints. I will take it off again to install the detector behind the grills and maybe add some leds drls while I am at it.
