How to Replace the Timing Belt on a 2002 Hyundai Accent 1 6L DOHC

The Accent is a subcompact car that Hyundai began manufacturing in 1994. The 2002 model is a second generation Accent, which includes the 1999 through 2004 models. Hyundai introduced a 4-cylinder, 1.6-liter engine with a double overhead camshaft in 2002. This engine uses a timing belt to drive the camshafts with the crankshaft, allowing the cylinder valves to open and close in the correct sequence. The timing belt in a 2002 Hyundai Accent lasts about 60,000 miles.

Instructions

    1

    Remove any components needed to access the cover for the timing belt. Disconnect the timing belt cover with a socket wrench.

    2

    Rotate the crankshaft clockwise to align the timing marks. The timing mark on the crankshaft sprocket must align with the timing mark on the front of the crankcase. The timing mark on the camshaft sprocket must align with the timing marks on the cap of the camshaft.

    3

    Loosen the tensioning bolt and pivot bolt on the timing belt tensioner with a socket wrench. Pull the tensioner towards the water pump as far as possible and tighten the adjusting bolt to hold the tensioner in place.

    4

    Align the timing marks for the crank shaft sprocket and camshaft sprockets, if necessary. Place the timing belt onto the crankshaft sprocket, camshaft sprocket, and belt tensioner wheel, in that order. Turn the camshaft sprocket counterclockwise to take up the slack in the timing belt. Turn the crankshaft clockwise to align the timing marks once again.

    5

    Loosen the mounting bolts for the timing belt tensioner with a socket wrench to place tension on on the timing belt. Ensure that all of the teeth on the camshaft sprocket engage the timing belt.

    6

    Tighten the adjusting bolt on the timing belt tensioner with a socket wrench. Torque the pivot bolt to between 15 and 18 foot-pounds with a torque wrench. Turn the crankshaft one full turn clockwise to seat the timing belt. Ensure that the timing marks on the crankshaft align once again.

    7

    Loosen the attaching bolts on the timing belt tensioner with a socket wrench to allow the tensioner to position itself. Adjust the tension on the timing belt by turning the tensioner wheel. The timing belt is at the correct tension when you pull the timing belt toward the water pump and the teeth of the timing belt come halfway across the tensioner adjusting bolt.,

    8

    Replace the covers for the timing belt. Install any components you removed in step one to access the timing belt.
