How to replace the lower intake manifold on Chevrolet Silverado 1500?

You should start the lower Intake Manifold replacement by draining coolant from the system. Extract the fuel hoses/lines and the Ignition Coil assembly and the evap canister tube from the system. First detach heater hoses and set them aside before disconnecting the engine wiring harness electrical connector from both the Throttle Body and designated electrical connections. First remove the engine harness clamp and oil pressure sensor connector with the engine wiring harness bracket bolt before relocating the wiring harness. Turn off your positive crankcase ventilation (PCV) valve hose in addition to the power Brake Booster Vacuum Hose while also removing the radiator inlet hose and water pump inlet hose. The first step to access the front Intake Manifold bolt requires Drive Belt removal followed by loose power steering (P/S) pump rear bracket nut and subsequent forward sliding of the p/s pump bracket. Rip the bolts from the lower end of the Intake Manifold then take out both the manifold and its gaskets for disposal. Thoroughly examine and clean the lower Intake Manifold according to need. Each end of the Intake Manifold Gasket needs a 4.0 mm adhesive patch applied to the cylinder head side while keeping the gasket properly seated during the adhesive's wet stage. Start by applying a 5 mm adhesive bead across the front and rear block tops which should reach up to the Intake Manifold gaskets before installing the manifold. Reused fasteners require threadlock application to lower Intake Manifold bolts followed by a stepwise bolting process according to torque specifications. Finally, the p/s pump bracket should be reattached while the Drive Belt installs and water pump inlet hose and radiator inlet hose should be reconnected. Reconnect the power Brake Booster Vacuum Hose along with the PCV Valve Hose before you put the engine wiring harness and its components in their proper positions and secure them. To finish the process add coolant into the cooling system.
