It is recommended that you change the timing belt on your 2003 Hyundai Tiburon every 60,000 miles. Without this regular maintenance, the timing belt can wear and even break causing damage to your engine. Timing belts are relatively inexpensive and easy to replace yourself.
Raise the passenger side of the car with the jack. Position the jack so that it is under the front axle.
Place the jack stand under the car and lower it. Remove the jack.
Loosen the lug nuts on the front passenger side tire. Take off the lug nuts and the tire and put them aside.
Unfasten the bolts holding the engine splash shield located underneath the engine.
Turn the bolt on the center of the timing belt tensioner pulley clockwise with a socket wrench.
Take the old timing belt off of the alternator pulley. Keep the tensioner pulley turned clockwise until the belt is off. Then let the tensioner slowly move back into place.
Place the new timing belt around the alternator pulley. Hold it tight against the pulley.
Move the tensioner pulley forward again by turning it clockwise with a socket wrench.
Let go of the tensioner pulley once you are sure the timing belt is securely in place.
Check that the timing belt is tight and then replace the engine splash shield.
Replace the tire and remove the jack stand.
