  Q: How to replace the intake manifold on Cadillac CTS?

  A: To replace the Intake Manifold, first, switch the ignition off and then remove the fuel injector sight shield. Then remove the air outlet duct and unplug the Brake Booster Vacuum Hose, purge solenoid valve electrical connector, and purge line from purge solenoid valve. Remove the retainer and disconnect the throttle body electrical connector. Then gap the upper Intake Manifold brace stud , bolt , brace, disconnect the positive crankcase ventilation (PCV) hose from the right bank camshaft cover, the barometric pressure sensor electrical connector, and the Intake Manifold runner control solenoid electrical connector. Take out the bracket bolts that hold injector harness bracket, and we will also remove the left bank ignition coil wiring harness and should have no problems with that, then removing the upper Intake Manifold bolts, and there might be some deflection of the cowl panel that might be needed to pull the right rear bolt. Remove the upper Intake Manifold while it contains the throttle body and in the process of replacing disassemble the Intake Manifold, clean and inspect it. For installation, if necessary, assemble the Intake Manifold, put a new upper Intake Manifold gasket back in place, and then the upper Intake Manifold. Tighten the Intake Manifold mounts in a circular fashion from the middle (long bolts) and finish to 23 n.m (17 lb ft). Join the barometric pressure sensor electrical connector, Intake Manifold runner control solenoid electrical connector, and pcv hose to the right bank camshaft cover. Mount the upper Intake Manifold brace, stud, and bolt compressing the brace bolt to 65 n.m (48 lbft) and brace stud to 10 n.m (89 lb in). Make sure to properly engage the wiring harness connector and then attach the electrical connector to the throttle body, installing the wiring harness retainer, attaching the purge line to the purge solenoid valve, and the purge solenoid valve electrical connector. Lastly, attach the Brake Booster Vacuum Hose to the Intake Manifold, place the spare air outlet duct, and reinstall the fuel injector sight shield.

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

  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.

  Q: How to replace the intake manifold on Cadillac XLR?

  A: The first step for Intake Manifold replacement requires complete removal of the Fuel Rail system. You need to loosen the plenum duct clamp at the Intake Manifold front then remove the 10 bolts holding the Intake Manifold to the cylinder heads. Remove the Intake Manifold by lifting it upward starting from the back end while conducting inspection and cleaning of the components. The inside edge of rubber plenum duct requires light lubrication while removing debris from the cylinder heads and Intake Manifold before you install new gaskets on the Intake Manifold. Coordinate the installation of the Intake Manifold by tightly securing the PCV Valve Hose to its fitting at the rear portion. Place the Intake Manifold front end inside the plenum duct before lowering the rear section onto the cylinder heads. Begin by installing the Intake Manifold bolts loosely onto the cylinder heads but apply torque in a sequential order (1-10) reaching 10 n.m (89 lb in). Tighten the plenum duct clamp at the front of the Intake Manifold to 2.25 n.m (20 lb in). Check for fuel leaks by cycling the ignition through on for 2 seconds then off for 10 seconds before returning to on. Reinstall the Fuel Rail assembly before this check. The conclusion of this installation effort involves placing and securing the fuel injector sight shield.
