Removal & Installation




CAUTION
Timing belt maintenance is extremely important. All Hyundai models use interference-type non-freewheeling engines. Should the timing belt break in these engines, the valves in the cylinder head will come in contact with the pistons, causing major engine damage. The recommended replacement interval for timing belts is 60,000 miles.

  4.  
  5. Install the idler pulley and tighten the bolt to 32-40 ft. lbs. (43-55 Nm).
  6.  
  7. Temporarily install the timing belt tensioner with a plain washer.
  8.  
  9. Position the timing belt over the crankshaft sprocket, inside the idler pulley, over the camshaft sprocket and then inside the timing belt tensioner.
  10.  
  11. Rotate the crankshaft clockwise the angle equivalent of two teeth of the camshaft sprocket.
  12.  
  13. Give tension to the timing belt by rotating the tensioner in the direction of the arrow. Tighten the tensioner bolt to 32-40 ft. lbs. (43-55 Nm).
  14.  
  15. Check the belt tension by depressing the center of the belt span with an index finger. The deflection should be 0.16-0.24 inches (4-6 mm). Adjust if necessary.
  16.  
  17. Turn the crankshaft clockwise two turns and realign the crankshaft and camshaft sprocket timing marks.
  18.  
  19. Install or connect the following:

    Lower timing belt cover. Tighten to 6-7 ft. lbs. (8-10 Nm).
     
    Flange and crankshaft pulley. Tighten to 125-133 ft. lbs. (170-180 Nm).
     
    Upper timing belt cover. Tighten to 6-7 ft. lbs. (8-10 Nm).
     
    Water pump pulley
     
    Accessory drive belts
     
    Engine mount bracket. Tighten engine side bolts and nuts to 37-48 ft. lbs. (50-60 Nm). Tighten body side nut to 44-59 ft. lbs. (60-80 Nm).
