I recently posted a question concerning my 2000 GTS's idler pulley. After researching things a little, I've learned this is actually referred to as a "Belt Tensioner Assembly" and seems to be a pretty common problem on 2000 GTS models. I found the TSB and this thing looks to be a bear to fix. There's just no room. Has anyone tackled this repair, or can someone give me an idea of what the dealerr cost is to do the repair?
