• Q: How to replace the intake manifold on 2001 Cadillac Catera?

  A: Replacing an Intake Manifold requires plenum removal and fuel system pressure relief and Fuel Rail detachment of both the supply hose and return hose. Begin by connecting to the fuel injector electrical harness connector and removing the vacuum line that leads to the Fuel Pressure Regulator. You should carefully unbolt the Intake Manifold while using masking tape to prevent foreign things from getting into the engine space and protect machined aluminum surfaces from damage. Clean the sealing surfaces of the Intake Manifold with a nonabrasive tool or solvent then remove all masking from the intake ports before installing a new Intake Manifold. Screw in the Intake Manifold bolts before tightening them to 20 nm (15 ft. Lbs.). Prior to mounting the connections counterhold them to stop Fuel Rail damage. Attach the Fuel Pressure Regulator vacuum line and the fuel injector electrical harness connector. Finally, install the fuel supply hose and tighten its connections to 15 nm (11 ft. Lbs.)after tightening the fuel supply hose at 15 nm (11 ft. Lbs.) users need to proceed by securing the fuel return hose at 15 nm (11 ft. Lbs.) before reinstalling the intake plenum.
