timing belt replacement on 2001 volvo s60 on 2001 Volvo S60

Along with my timing belt on my 2001 volvo s60, what else should be replaced.?? The tensioner or idler? also is that called camshaft belt idler and belt tensioner?

Replace both tensioners AND the water pump as well.It's also a good time to change all external belts as well,if you havent done it in a while. At this point they are loosened up or off anyhow, so No problem. Just did this 10k miles ago on my '02 S60. Hope this helps.-Steve
The timing belt tensioner has to be replaced, and then the water pump and idler pulleys are also a good idea too.
