69J3D11 1-10123456789TensionerA timing chain tensioner is provided at the mid-span of the timing chain, between both camshafts.The timing chain tensioner uses the force of a spring to maintain its tension. After the engine isstarted, oil is pumped into the tensioner, and the resulting pressure causes the tension to increase.A total of three tensioners are used, one for the timing belt, and one for each timing chain of bothbanks, to maintain proper tension and to ensure the reliability of the valve train.1 Intake camshaft2 Exhaust camshaft3 Timing chain4 Timing chain tensioner5 Hydraulic timing belt tensionerS69J1300Features and benefits
