• Q: How to replace the intake manifold (500) for RPO L92 - Second Design on 2007 Cadillac Escalade EXT?

  A: To remove the Intake Manifold (500) for rpo l92-second design, remove the air cleaner outlet duct, the generator and engine harness retainer nut, and then unfasten the engine harness retainer from the stud and locator pin. Disconnect the engine harness connector from the evap canister purge solenoid , manifold absolute pressure (MAP) sensor , ignition coil harness , left side fuel injectors , throttle actuator , right side fuel injectors , and engine coolant temperature (ECT) sensor . Secure and collect the engine harness branches to the cowl panel, brake booster vacuum hose clamp and unsecure the Brake Booster Vacuum Hose from the booster fitting. Disconnect the evap canister purge tube, fuel feed line quick connect fittings, detach the positive crankcase ventilation (PCP) hose, and loosen the Intake Manifold bolts (512). With help, remove the Intake Manifold (500) and close the passages to the cylinder head to avoid debris intrusion. Remove the Intake Manifold gaskets (514) and, in case of changing the manifold, reinstall the Brake Booster Vacuum Hose clamp, disconnect the vacuum hose from the manifold nipple, and disconnect the upper Intake Manifold cover and MAP Sensor. Airport the evap tube quick conn cable sediment, remove evap benign purge solenoid retainer, eradicate the throttle assembly and Fuel Rail eliminating the Throttle Body resort and Fuel Injector bottom sheaves. To install, connect the Brake Booster Vacuum Hose nipple to the new Intake Manifold, install new Fuel Injector lower o-ring seals greased up in the new clean engine oil, and install the Fuel Rail, tightening the bolts up to 10 n.m (89 lb in). Replace with a new Throttle Body Gasket along with the Throttle Body and tighten with bolts/nuts at 10 n.m (89 lb in). Connect the evap tube and purge solenoid back, lubricate the MAP Sensor seal, and mount the MAP Sensor and retainer. Mount the upper Intake Manifold cover and the nut up until it is snug, reconnect the Brake Booster Vacuum Hose and tighten it. Replace new Intake Manifold gaskets (514), remove the covers of the cylinder head passages and install the Intake Manifold (500), then fasten bolts (512) initially to 5 n.m (44 lb in) and then to 10 n.m (89 lb in) accordingly to the specified sequence. Hook back the pcv hose, fuel feed line, and evap canister purge tube. Attaches the Brake Booster Vacuum Hose to the booster fitting, takes off the branches from engine harness and connect the ect sensor. Tighten the engine harness clip to the generator bracket using a bolt assembled with a torque of 9 n.m (80 lb in) reconnect right side fuel injectors, ignition coil harness, and left side fuel injectors install cpa retainers and check as well as install the MAP Sensor and evap canister purge solenoid. Lastly, install the engine harness retainer to the stud and locator pin, tighten the retainer nut to 5 n.m (44 lb in) and reinstall the generator, finishing off with the attachment of the air cleaner outlet duct.
