Fig. 7.27. Check the timing belt for cracks or missing teeth. Also check the pulleys for nicks and other irregularities
28. Check the belt tensioner for visible oil leakage. If there is only a slight trace of oil on the pushrod side, the tensioner seal is in satisfactory condition.
29. Grasp the tensioner with both hands and press the tensioner firmly against a stationary object (Fig. 7.29). If the plunger moves, replace the tensioner.

30. On 1999-2003 vehicles, measure the plunger protrusion from the housing (Fig. 7.30). Compare the measurement result with the value given in Specifications at the beginning of this chapter. If the protrusion is not within specification, replace the tensioner.
