To replace the left side Camshaft start off by removing the upper
Intake Manifold and below (the lower Intake Manifold). Next, remove the Camshaft cover of the left bank and the Camshaft sensors. Next, the Camshaft position actuator solenoid gets detached. Apply the crankshaft balancer only in a clockwise direction using the crankshaft balancer bolt, to align the camshafts into a neutral position, ensuring that the flats on the camshafts are running parallel with the Camshaft cover rail. Loose the Camshaft position actuator bolt by using an open-end wrench at the hex of the Camshaft to prevent rotation. Unscrew the en-48313
Timing Chain retention tool (EN-48313) to allow the legs to be drawn back and then insert the tool between the Camshaft actuators making sure that the bottom of the tool aligns with the top surface of the cylinder head. Partially expand the legs of the en-48313 turning the t- shaped handle clockwise, and insert one leg behind the
Timing Chain Guide expanding days till the legs touch the Timing Chain without tightening. Hand tighten the en-48313 and rotate the camshafts together to induce slack in the chain. Mark on Timing Chain and the position where it is at respectively on Camshaft position actuators prior to removal of Camshaft position actuator bolt and the camshafts. For referral, align the marks on either side on the Camshaft position actuator and the Timing Chain and then place the Camshaft actuators with the containing camshafts and install them with corresponding Camshaft bearing caps. There should be removal of the en-48313 with an eye for an open-end wrench at the Camshaft hex in order not to rotate, and then work should be shouldered on the Camshaft position actuators and tightened. Lastly, install the intake Camshaft position actuator solenoid, the Camshaft sensor, the Camshaft cover, and reassembly the upper Intake Manifold with the lower Intake Manifold.
