    Q:
    How to replace the air hose outlet duct on Buick Lucerne? Posted by Customer
    A:
    To replace the air cleaner outlet duct, you will have to remove the intake manifold cover. Remove the mass air flow (MAF)/intake air temperature (IAT) sensor engine harness electrical connector from the pcv tube quick connect fitting on the air cleaner outlet duct. Loose the air cleaner outlet duct clamp at the Throttle Body and remove the duct from the Throttle Body and then loose it from the maf/iat sensor and removing it from the vehicle. In installing, align the air cleaner outlet duct to the vehicle and the maf/iat sensor, then tighten the clamp at the maf/iat sensor to 4.n.m (35 lb in). Next, connect the duct to the Throttle Body and tighten the corresponding clamp to the same torque specification. Join pcv tube quick connect fitting to the air cleaner outlet duct and the maf iat sensor engine harness electrical connector. Finally, install the intake manifold cover back onto its position.

    Q:
    How to Service and Repair the Air Hose? What Steps Are Involved on a Buick Lucerne? Posted by Customer
    A:
    Start by removing the intake manifold cover before disconnecting three components: engine harness electrical connector from maf/iat sensor, electrical connector from maf/iat sensor to the air cleaner outlet duct, and pcv tube quick connect fitting from the outlet duct. Begin by removing the air cleaner outlet duct from the Throttle Body while simultaneously loosening its clamp at the Throttle Body. Then unscrew the duct from the maf/iat sensor before complete removal. Installation requires the air cleaner outlet duct assembly between the vehicle and the maf/iat sensor while tightening the maf/iat clamp to 4 n.m (35 lb in) of torque. You should install the duct to the Throttle Body before tightening its clamp at an identical torque setting. The pcv tube quick connect fitting should get reattached to the air cleaner outlet duct and the engine harness should reconnect its electrical connector to the maf/iat sensor before finishing with intake manifold cover replacement.
