4. Rotate the crankshaft again 1 3/4 revolutions (about 1/4 turn before No. 1 cylinder TDC). Then remove the vibration damper from the crankshaft.
4. Remove the two nuts and bolt that hold the lower camshaft drive belt cover to the coolant pump and to the front of the engine. Remove the lower
cover.
5. Loosen the camshaft drive belt tensioner locknut. Turn the tensioner counterclockwise so that the tension is removed from the drive belt. Then
remove the drive belt by working it off the sprockets.
CAUTION: Rotating the crankshaft or the camshaft with the drive belt removed may cause interference which can damage pistons and valves.
6. Inspect the tensioner bearing and the belt. Spin the bearing to check that it runs smoothly. Inspect the drive belt for any visible damage such as
stretch, exposed threads, missing teeth, or any other visible damage. A damaged belt or worn tensioner should be replaced.
NOTE: Failure of the sealed tensioner bearing is a possibility. On a high-mileage engine, consider replacing the tensioner when replacing the belt.
