To replace the Camshaft (except RPOs LC9, LMG, LY2, LY5) one must begin by removing the radiator support followed by the valve lifters before removing the engine front cover and Starter motor. Install the j 42386-a (Flywheel Holding Tool) so its teeth interlock with the engine Flywheel teeth before using one m10-1.5 x 120 mm and one m10-1.5 x 45 mm bolt to bolt the j 42386-a and secure both bolts at 50 nm (37 lb ft). Use the crankshaft sprocket to rotate until both alignment marks between the cmp actuator and the crankshaft sprocket become perfectly lined up. Disconnect and remove the cmp actuator solenoid valve (234) before removing the cmp actuator (235) as well as the Timing Chain (208). Unscrew the bolts (204) along with the retainer (203) of the Camshaft while watching out for Camshaft bearing damage. Unscrew the Camshaft sprocket bolt through the front bolt hole of the Camshaft and employ the bolt as a tool for cautious Camshaft extraction from the engine. Clean engine oil serves to lubricate the Camshaft journals and bearings before you should use the bolt to handle the Camshaft duringinstallation into the engine block. First tidy the gasket surface of the engine block before installing the Camshaft retainer (203) together with bolts (204). Tighten hex head bolts of the first design to 25 nm (18 lb ft) and torx® head bolts of the second design to 15 nm (11 lb ft). Install en 46330 (Timing Belt Tensioner Retaining Pin) by compressing the Timing Chain tensioner guide while keeping cmp actuator and Timing Chain in proper alignment. The installation of cmp actuator solenoid valve (234) requires light hand tightening before assessing sprocket alignment. The cmp actuator solenoid valve needs first tightening to 65 nm (48 lb ft) then a single pass to a 90-degree angle by using the j 45059 (Angle Meter). During this procedure, remove the en 46330. First remove the j 42386-a and bolts before restating the Starter motor and engine front cover with valve lifters before finishing with the radiator support.
