Question 1

How to replace the left side camshaft on GMC Acadia?

Accepted Answer

To replace the left side Camshaft get both the en-48313 Timing Chain retention tool (EN-48313) and en 46111 Crankshaft rotation socket (EN 46111). The procedure to replace the side Camshaft starts with removing the lower Intake Manifold and then proceeding to the left bank Camshaft cover. The second step involves removing both the Camshaft sensors together with the Camshaft position actuator solenoid. The en 46111 will rotate the Crankshaft to achieve Camshaft neutrality while both Camshaft flats align perpendicular to the Camshaft cover rail. An open-end wrench should be placed at the Camshaft hex point to stop it from rotating then you can loosen the Camshaft position actuator bolt. Use the en-48313 by unscrewing its legs before sliding it between the Camshaft actuators while keeping the scribed line next to the cylinder head. Extend the legs of en-48313 partially until one leg reaches behind the Timing Chain guide before continuing the expansion to contact the chain without torque. Operate the en-48313 by hand until the camshafts meet each other to produce chain slack. Begin the process by marking the Timing Chain together with Camshaft position actuators for correct reassembly before uninstalling the Camshaft position actuator bolt and the camshafts. Installation requires correct alignment between Camshaft position actuator and Timing Chain marks before installing the Camshaft actuators to the camshafts with Camshaft bearing caps. Begin by removing en-48313 while using an open-end wrench for prevention of rotation and proceed to correctly install and tightly fasten the Camshaft position actuators. Afterward install the intake Camshaft position actuator solenoid together with Camshaft sensors and Crankshaft balancer and Camshaft cover and lower Intake Manifold.

How to replace the camshaft on GMC Sierra 1500?

Accepted Answer

Begin by putting the hood in service position then remove the hinge bolts before raising the hood vertically until the bolts are tight in the service position. Proceed with the removal of the radiator support followed by removing the front cover along with valve lifters and Camshaft sensor bolt and sensor. First align the timing marks on Crankshaft and Camshaft sprockets following proper Crankshaft rotation before you uninstall the Camshaft sprocket bolts. The Crankshaft assembly must not receive any rotating force after taking out the Timing Chain because it will cause damage to piston assemblies or valves. Start by removing the Camshaft sprocket and relocating the Timing Chain after which you can install the Camshaft retainer bolts and retainer. All Camshaft journals share the same diameter so keep them in mind to stop causing damage to the Camshaft bearings when removing the Camshaft. Install three m8-1.25 x 100 mm (M8-1.Three bolts (M8-1.25 x 100 mm (M8-1.25 x 4.0 inch)) should be installed into the front bolt holes of the Camshaft before using these bolts as handles to gently extract the Camshaft from the engine block and then removing them. Clean and inspect the Camshaft and bearings only when needed. Install clean engine oil on every Camshaft journal and bearing prior to putting the same three bolts into their correct positions in the engine block to install the Camshaft. Install and tighten the Camshaft retainer plate by placing this element with its gasket surface facing the engine block while maintaining a debris-free condition of the gasket surface before installing the retainer plate and its bolts to a torque setting of 25 nm (18 ft. Lbs.). Place the Camshaft sprocket onto its position followed by installing the Timing Chain. Secure the Camshaft sprocket bolts at 35 nm (26 ft. Lbs.). Examine the Camshaft sensor o-ring seal to check for signs of damage. For an undamaged sensor apply engine oil before placing the Camshaft sensor while its bolt requires 25 nm (18 ft. Lbs.) torque. End your installation with the valve lifters and front cover and radiator support components. Complete the installation by lowering the hood and reinstalling its bolts according to a torque setting of 25 nm (18 ft. Lbs.).
