I am about to change out the serpentine belt on my folk's '97 E320 with auto trans. Is this a DIY job? I took a look at the car this afternoon and seems like there's not much room there, maybe the raditor needs to be taken out before I can get my hands in there. I've changed the timing belt and serpentine belt on my Audi before and that's was a pain. I hope this E320 would be easier, but since I am not familier with this car at all, can someone tell me what's the steps? I've searched several places and came up nothing. Is there any other belts like a/c or p/s I should be changing out while I am in there? thanks
