2001, 1.6 Litre, Hyundai Accent Timing Belt Tensioner

I was wondering if both 12mm bolts for the timing belt tensioner need to be tightened? It appears that if you tighten them it would restrict the tensioner from doing its job, but I don't want them to back out (by themselves when running) if I leave them loose enough to allow the spring to apply tension. Any help would be appreciated.

Thanks - Don

Hi there,

Both these bolts must be tight. The outer off the two bolts is the pivot, and the inner is the adjuster. To back off adjuster, back off both blots and rotate tensioner anti clockwise, to release tension from belt this is against spring tension so to hold off nip up the inner bolt to hold it. Replace belt, checking alignment marks. Slacken inner bot allow tensioner to operate (do not force extra tension by hand) do up both bolts to 20-27 Nm. Rotate engine one revolution. Back off both bolts, allow tensioner to operate (this will allow the tensioner to take up any slack after the belt has seated in the pulleys) Re tension both bolts to 20-27 Nm. Turn crank shaft one revolution and re check alignment. Always make sure that the tensioner and guide pulley bearings are serviceable and the tensioner spring is serviceable as well.
