The Camshaft replacement starts by removing the radiator support, engine front cover, valve lifters together with the Camshaft sensor bolt and sensor. Check the alignment of the timing marks between
Crankshaft and Camshaft sprockets before rotating the engine until the
Timing Chain comes out so you can protect the piston assemblies and valves from damage. Next remove the Camshaft sprocket and move the Timing Chain into position before installing the Camshaft retainer bolts together with the retainer where technicians need to exercise caution to protect the Camshaft bearings because all Camshaft journal dimensions are identical. Use three bolts with m8-1.25 x 100 mm size (M8-1.25 x 4.0 inch) to insert into the front holes of the Camshaft retaining plates before extracting it from the block by holding it as a lever. The Camshaft and its bearings need inspection for possible cleaning if necessary. Begin by applying engine oil to Camshaft journals and bearings and re-install the Camshaft into the engine block using the three previously used bolts and remove them afterward. Install the retainer plate so its sealing gasket faces the engine block and confirm that the gasket surface of the engine block remains clean. Install the Camshaft retainer along with bolts and tighten them to 25 nm before putting the Camshaft sprocket and position the Timing Chain. Finish by tightening Camshaft sprocket bolts to 35 nm. To proceed with installation it is necessary to check for damage on the Camshaft sensor o-ring seal. Once you find it intact apply clean engine oil and put the Camshaft sensor and bolt into position. Package this hardware assembly with a bolt torque setting at 25 nm (18 ft. Lbs.). Complete the installation sequence by putting in all valve lifters and the front cover and radiator support.
