Juan--serpentine belt usually changes out at 60K miles, or 100K kilometers. Standard practice. Timing belt at 70K miles. If you're at 68K you should do the 100K kilometer maintenance thing, which is fuel filter, thermostat, serpentine belt, fluids, etc. Be aware that Volvo changed the routing on the serpentine belt on some models, and if and when you order it from Volvo (don't do aftermarket on this item), you will get a diagram showing you the new routing. The new routing takes a belt a fraction of an inch longer than the original, and if you use the old routing with the new belt it will be too loose when you release the tensioner pulley. If you buy an aftermarket belt, you probably won't get the diagram that comes with the new belt from Volvo. As a suggestion, when you take the old serpentine belt off and install the new, wrap it around the outside pulleys first and then pinch a small loop with the remaining belt and slip it last over the inside tensioner pulley. The outside pulleys all have a little shoulder on them, and it's a real bitch to try and slip the belt over the final pulley with a shoulder on it. Lots of swearing and stretching involved in that one. The idler pulley has no shoulder, and if you double the belt with what's left, making a small loop, pray a little bit, bend down and look, it will slip right on the inside shoulderless pulley with no trouble. Release the tensioner pulley and you're home free. Dick
