My S6 (V8 4.2L C4 platfrom) is due for a timing belt change. Water pump and engine is very quiet when running. I want to simply fit a new belt for now, and re-use the old tensioner and idler pulley, if they look good.

I planned on lining up all the timing marks before removing the old belt. So will I really need a camshaft holding tool?
