The timing belt, or spur, camshaft or toothed belt, should be inspected from time to time, especially on 1.8L 4-cylinder engines. The 3.2L 6-cylinder features a timing chain instead of a timing belt, so you don't have to service it. To check the belt, remove the upper sound absorber panel and the upper turbocharger air duct as needed, and then release the clips of the upper belt cover. Gently extract the scale from the cylinder head to uncover the timing belt. Examine the belt for separation between layers, chunking or breaking of material, oil and grease contamination, missing or broken drive cogs, and insufficient tension contact with the belt covers. The cover material should be inspected for cracks and chafing and wear of edges with fraying of the cord material and cracks on the drive side. You should check the tensioner to see if it is worn and damaged any further. If so, replacement of the belt is necessary. Consult maintenance tables for guidance on routine replacement intervals and belt replacement procedures.
