My 2000 2.9L S80 is due for a new timing belt and I plan to replace it myself. Is there anything special about this job I need to know? Any special tools required? I've found sites that document changing the timing belts on other Volvo models, but not the S80 and I have to wonder why. I'm a decent back-yard mechanic, but I've never worked on a Volvo yet. I plan to replace the timing belt, idler/tensioners as well as the water pump, hoses and serpentine belt. Any advice or feelback would be welcome.
