Timing Belt Tensioner: Testing and Inspection

Check the timing belt tensioner and timing belt idler for smooth rotation and any binding or abnormal noise. Do not clean the timing belt tensioner or timing belt idler with cleaning fluids. Use a soft, clean rag to wipe the timing belt tensioner and timing belt idler. Avoid scratching these components.





Inspect the timing belt tensioner spring for abnormal shape and weak retraction. The free length of the timing belt tensioner spring should be 36.6 mm (1.441 inches). If necessary, replace the timing belt tensioner spring.
