How to replace the left side camshaft on GMC Acadia?

The left side Camshaft replacement process starts with lower Intake Manifold disassembly and then moving to remove the left bank Camshaft cover and the Camshaft sensors together with the Camshaft position actuator solenoid. The Crankshaft balancer needs removal before rotating the Crankshaft with the Crankshaft rotation socket (EN 46111) to position the camshafts at their neutral (low tension) orientation with flat surfaces parallel to the Camshaft cover rail. The hex-side wrench on the Camshaft serves to maintain engine and Camshaft stability but the technicians do not untighten the Camshaft position actuator bolt yet. Fully extend the Timing Chain retention tool (EN 46108) into the Timing Chain while tightly securing its nuts until both Camshaft Timing Chain and Camshaft position actuators receive proper assembly marks. Before removing the Camshaft position actuator bolt and camshafts you need to mark both the Timing Chain and respective positions on the Camshaft position actuators. The first step of installation requires timing the marks on both the Camshaft position actuator and Timing Chain to match before leaving the Camshaft position actuator bolt loose. The cylinder head should receive the camshafts after aligning them correctly while installing the Camshaft bearing caps and Camshaft actuators. Take off the Timing Chain retention tool (EN 46108) via an open-end wrench at the Camshaft hex avoiding Camshaft rotation. Assemble and snugly fasten the Camshaft position actuators before installing the intake Camshaft position actuator solenoid then the sensors and Crankshaft balancer and Camshaft cover and ending with the lower Intake Manifold.

Camshaft in GMC Acadia automobiles regulates the opening and closing of the valves responsible for combustion in the engine. These camshafts can be block-mounted or cylinder head-mounted commonly with varieties like Over Head Valve (OHV), Single Over Head Cam (SOHC), and Double Over Head Cam (DOHC) designs. With this, the camshaft is in harmony with the crankshaft in that the valves will open and close and pistons move as required at appropriate angles. Some bolt-on upgrades include the fitting of performance camshafts to boost power output; all related variables ranging from the compression ratio to vehicle weight must be considered. The performance camshafts usually have more lift and longer duration thus more air flow and power at high r.p.m. Lobe Separation Angle (LSA) is another significant parameter on torque, cylinder pressure, and idle quality. In general, the camshaft remains a very important component that hugely influences the engine power output and torque.
