The reason the other cars don't destroy themselves when the timing belt breaks is because the piston can't possibly hit an open valve in any position. In saabs, the piston can hit an open valve if the chain breaks and the valve is open when it shouldn't be. The good thing is we have chains while most other cars have belts. The chains last quite a bit longer. I think the recommended change interval for most belts is around 60k-80k, maybe more on some. Most saabs can run 200k+ with the chains. IF the serpentine belt breaks it will not ruin the engine. But it will overheat fairly fast since the water pump isn't turning. IF you ever hear it snap and see the temp gauge run up very fast..turn the engine off fast and it'll be fine. I'm more concerned with the balance shaft chains and sprockets on our '92 9000T. They are known to snap so I plan on replacing them very soon with 150K on the car.
