I just went down to my '98 S70 to check the type of timing belt/tensioner to order. I looked at the timing belt cover and the sticker on it was dirty, so I wiped it with my hand and... the ink rubbed right off along with the dirt! Now I only have remnants of bar code and no numbers at all left on that label. Is there a way I can determine the S/N of my engine without that sticker? Should I just take the timing cover off and determine the type of tensioner (auto vs. manual) and order parts accordingly? Do I need to replace the tensioner when replacing the timing belt for the first time at 65K miles? If the tensioner is auto type, do I replace the tensioner pulley? what about the idler pulley? I do not want to have my car un-drivable for a long time, so I would rather have all the parts necessary and do the job all at once instead of taking everything apart and then ordering parts.

Please help!
