Q: Why does the timing chain on a Saab 9-3 ('98-'02) 2.0-litre engine need to be replaced at 60,000 miles? Most timing chains last around 200,000 miles and are replaced as needed.
Phil PettA: You're right - timing chains shouldn't need changing at 60,000 miles. They generally last longer than timing belts.
However, some Saab 2.0-litre petrol engines gained a reputation for developing an oil starvation problem, which could lead to the timing chain failing prematurely.
That's why Saab says the chains need to be changed at 60,000 miles.
That's also why we mention this in our online used car review of the Saab 9-3 - we want to make buyers aware that this could be an issue, so that they can make sure it has been changed before they buy.
