Timing Belt Change mileage on Matrix
 

Could anyone advise me on the service mileage that the timing belt needs to be changed on my 55 Matrix common rail 1500 diesel? The car is coming upto 50000miles. I have read conflicting mileages for this varying from 30000 to 70000miles. I know the gates belts are well capable of 70000miles has many are fitted has factory standard to most Euro. diesels.
But I am unsure if Gates belts are factory fitted to Hyundai matrix 1500?

Thanks if u can help.:)
