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.

2.0L Engines
  1. Before servicing the vehicle, refer to the Precautions section.
  2. Remove or disconnect the following:

    Negative battery cable
    Engine coolant
    Water pump pulley bolts
    Alternator bolt, loosen only
    Water pump pulley and drive belts
    Crankshaft pulley
    Timing belt cover(s)

  3. Rotate the crankshaft clockwise and align the timing marks so No. 1 piston will be at Top Dead Center (TDC) of the compression stroke.
  4. Remove the timing belt tensioner and idler pulley.
  5. Mark the timing belt with an arrow showing direction of rotation.
  6. Remove the timing belt.

To install:

  1. Align the timing marks of the camshaft sprocket and check that the crankshaft timing marks are still in alignment.
  2. Install the timing belt tensioner.
  3. Install the idler pulley, if equipped. Tighten bolt to 32-41 ft. lbs. (43-55 Nm).
  4. Position the timing belt over the camshaft sprocket, then over the crankshaft sprocket.
  5. Tension the timing belt and tighten the tensioner pulley bolt to 32-41 ft. lbs. (43-55 Nm). When properly tensioned, the timing belt should deflect 0.16-0.24 in. (4-6mm) when a force of 5 lbs. (2.2kg) is placed on the longest span of the belt.
  6. Turn the crankshaft sprocket one turn clockwise and realign the crankshaft sprocket timing mark.
  7. Recheck the belt tension and adjust as necessary.
  8. Install or connect the following:

    Timing belt cover(s)
    Crankshaft pulley
    A/C compressor belt
    Water pump pulley
    V belt
    Negative battery cable
    Engine with coolant


3.0L & 3.5L Engines
  1. Before servicing the vehicle, refer to the Precautions section.
  2. Before servicing the vehicle, refer to the Precautions section.
  3. Remove or disconnect the following:

    Negative battery cable
    Engine coolant
    Water pump pulley bolts
    Alternator bolt, loosen only
    Water pump pulley and drive belts
    Crankshaft pulley
    Timing belt cover(s)

  4. Turn the crankshaft until the timing marks on the camshaft sprocket and cylinder head are aligned.
  5. Loosen the timing belt tensioner bolt and turn the tensioner counterclockwise as far as it will go. Tighten the adjusting bolt.
  6. Mark the timing belt with an arrow showing direction of rotation.
  7. Remove the timing belt.
  8. If defective, remove the timing belt tensioner.

To install:

  1. If necessary, install the timing belt tensioner.
  2. Attach the top of the tensioner spring on the engine coolant pump pin. Ensure the hook on the pin is facing down and the hook on the tensioner is facing away from the engine
  3. Rotate the timing belt tensioner to the extreme counterclockwise position. Temporarily lock the tensioner in place.
  4. Align the timing marks of the camshaft and crankshaft sprockets.
  5. Install the timing belt on the crankshaft sprocket, then onto the rear camshaft sprocket.
  6. Route the belt to the coolant pump pulley, the front camshaft sprocket and the timing belt tensioner.
  7. Apply force counterclockwise to the rear camshaft sprocket with tension on the tight side of the belt and check that timing marks are aligned.
  8. Loosen the tensioner bolt 1-2 turns and tighten the timing belt to a tension of 57-84 lbs. (260-380 N).
  9. Turn the crankshaft two turns clockwise.
  10. Readjust the sprocket timing marks and tighten the tensioner bolts.
  11. Install the timing belt covers.
  12. Install the crankshaft pulley and tighten to 108-116 ft. lbs. (150-160 Nm).
  13. Install or connect the following:

    Timing belt cover(s)
    Crankshaft pulley
    A/C compressor belt
    Water pump pulley
    V belt
    Negative battery cable
    Engine with coolant

The two attached drawings do not show up when clicked. If you cant show me the drawings this does not help me at all. I have directions I need the position marks to adjust the cam and crank.
