Kind of related but if you have that much in the fenders, you may have some goodies in your blower motor. There was a lot more than this before the photo and being that it's connected to the heater core, that was plastered with debris in the little radiator fins (if you will) as well.

In order of use: Center punch, small drill bit, larger drill bit, machinists scribe, 8 x 1.5 tap to clean the threads up, then new bolt with antisieze. I had to do all 4 on my 95.
