2005 Hyundai Tucson Question: Breaking timing belt /tensioner bolt

 

Question

The timing belt/tensioner bolt Has broken 3 times and mechanics can not find the reason.Last time did some motor damage and not under warranty so we have to fix it but if it is going to happen again I am wondering if it is worth the trouble . Several mechanics have been called and none can figure the reason.Timing belt was replaced at 60000 miles as maint. book stated and 3 week later bolt broke and has happened 2 times since then.My mechanics are very good and they are stumped.As is Hyundai !! Of course they will say it is because I didn't have it done by a cert.Hyundai mechanic !!

    You didn't say if the parts were OE or aftermarket, but here are my thoughts:
    There was a similar problem on some Audi / VW aftermarket tensioner bolt, which was recalled and removed from the shelfs - after many engine damage.
    I'd suggest to use the OE or a high grade bolt and tighten to the manufacturer's spec.
    Also make sure the cam and crank pulleys are clean, since rubber could build up from the original belt which could cause vibration.
