OK, maybe I shouldn't have called it "cake". IMO, any job that takes less than 30 minutes with a 100% success rate is cake, but I understand that a lot of people think changing the batteries in their TV's remote is a PITA. I still think that armed with the instructions from this site, as he posted he was, he would be successful doing it himself. The tensioner on our F350 is a mother to wrestle with, and we have to change that belt every year because for some reason they start squeaking. Anyway, I apologize for calling it "cake" as I realize doing so does not respect the different levels of DIY'ers here, and I certainly meant no harm to anyone with my attempt to inspire.
