Engines Powertrain
Timing Belt Tensioner
• An automatic timing belt tensioner is fitted to ensure optimum belt tension over the
service life of the engine.
• The timing chain tensioner operates using a hydraulic mechanism, which also
compensates the increased belt tension due to heat expansion of the engine
components.
