Acura 17110-P72-000 Manifold B, In.

To remove the intake manifold, first disconnect the cable from the negative terminal of the battery, ensuring you have the correct activation code for the radio if it has an anti-theft system. Drain the cooling system, then remove the intake air duct and air cleaner housing. Clearly label and detach any vacuum lines and electrical connectors that may interfere with the manifold removal, and detach the accelerator cable from the throttle lever. Remove the coolant hoses from the throttle body, relieve the fuel system pressure, and disconnect the fuel feed and return lines at the fuel rail. From underneath the engine compartment, remove the brace that supports the intake manifold by taking out the bolts. Disconnect the coolant by-pass hose from the intake manifold, then remove the intake manifold nuts and take the manifold off the engine. For installation, clean the manifold nuts with solvent and dry them with compressed air if available. Check the mating surfaces of the manifold for flatness using a precision straightedge and feeler gauges, and inspect the manifold for cracks and distortion, replacing it if necessary. Carefully check for any stripped or broken intake manifold bolts or studs and replace any defective bolts with new parts. Use a scraper to remove all traces of old gasket material from the cylinder head and manifold mating surfaces, then clean the surfaces with lacquer thinner or acetone. Install the intake manifold with a new gasket, tightening all the nuts finger-tight, and then follow the recommended sequence to tighten the nuts to the specified torque. The remainder of the installation process is the reverse of the removal steps.

To remove the intake manifold, first disconnect the cable from the negative terminal of the battery, ensuring you have the correct activation code for the radio if it has an anti-theft system. Drain the cooling system and remove the intake air duct and air cleaner housing, noting that on 1999 and later CR-V models, the intake air resonator chamber must also be removed. Clearly label and detach any vacuum lines and electrical connectors that may interfere with the removal process, paying special attention to the intake air bypass solenoid connector on B18C1 engines, which may be difficult to access. Detach the accelerator cable and, if applicable, the cruise control cable from the throttle lever, then remove the coolant hoses from the throttle body and the Idle Air Control (IAC) valve. Relieve the fuel system pressure and disconnect the fuel feed and return lines at the fuel rail. From underneath the engine compartment, remove the brace supporting the intake manifold by taking out the bolts. Disconnect the coolant bypass hose from the timing belt end of the intake manifold and remove the intake manifold mounting nuts before taking the manifold off the engine. If working on a manifold with a removable air chamber on B18C1 engines, separate it from the manifold as needed, along with any gaskets. For installation, clean the manifold nuts with solvent and dry them with compressed air if available, then check the mating surfaces for flatness using a precision straightedge and feeler gauge. Inspect the manifold for cracks and distortion, replacing it if necessary, and check for any stripped or broken intake manifold bolts or studs, replacing defective fasteners. Remove all traces of old gasket material from the cylinder head and manifold mating surfaces with a scraper, then clean the surfaces with lacquer thinner or acetone. Install the intake manifold with a new gasket, tightening the nuts finger-tight before following the recommended sequence to torque them properly. The remainder of the installation process follows the reverse order of removal.
