Earlier cars often used a metal chain, or even gears, to do this job. The 1. T 20 valve engine is driven by a timing belt system which links the cylinder head, camshafts, and crankshaft to run in sync. This VW Jetta timing belt system consists of a wear resistant, high strength, corded/molded rubber timing belt (a. VW Jetta toothed belt).
