Q: How to replace the secondary air inject check valve on Buick Lucerne?
A: The first step for changing the secondary air injection shutoff includes taking out the air cleaner outlet duct. The Brake Booster Vacuum Hose needs to be disconnected from the Intake Manifold before relocating it out of reach. The next task requires the removal of the engine harness electrical connector from the secondary air injection shutoff and check valve. Lift the vehicle before removing the bolts that secure the Intake Manifold cover bracket and subsequently removing the bracket itself. Jeep owners must lower their vehicle first while they remove the nuts that attach the air shutoff and check valve pipe to exhaust manifold. Detach the air feed tube bracket nut which is mounted on the throttle body stud before disconnecting the air feed tube quick connect fitting from the air shutoff and check valve assembly. Place the air feed tube on the throttle body stud but keep it in a different position. First install the upper bolts on the bracket of the air shutoff and check valve then proceed to remove both components from their positions. The technicians should discard the air shutoff and check valve to exhaust manifold gasket after cleaning both gasket sealing surfaces. New installation requires users to place a fresh air shutoff and check valve gasket on exhaust manifold studs before mounting the air shutoff and check valve . Fasten the air shutoff and check valve to bracket upper bolts while tightening them to 25 n.m (18 lb ft). Mount the air feed tube onto the throttle body stud before proceeding to connect the quick connect fitting of the air feed tube to the air shutoff and check valve assembly. The air feed tube bracket nut should be installed onto the throttle body stud then tightened to 10 n.m (89 lb in). Pontiac sunbird 1999 requires applicants to install the air shutoff and check valve pipe to exhaust manifold nuts at a torque of exactly 10 n.m (89 lb in). Connect the Intake Manifold cover bracket together with its bolts while torquing these fasteners to 30 n.m (22 lb ft). After lowering the vehicle the technician returns the engine harness electrical connector to the air shutoff and places the Brake Booster Vacuum Hose at its designated spot on the Intake Manifold before completing the installation with the air cleaner outlet duct.
Q: How to replace the Air Inject Check Valve on Buick LeSabre?
A: The first step for secondary air injection shut-off valve replacement is hose-disconnect from the combination valve. Begin by using the pinch clamp to loosen and lower the exhaust hose of the secondary air injection (AIR) pump. After that detach the 2 mounting bolts which connect the air pipe to the AIR manifold. To complete this task first remove the mounting bolt that connects the combination valve to the manifold air pressure (MAP) sensor bracket. Then extract the AIR combination valve together with its attached AIR pipe. First secure the AIR combination valve and AIR pipe assembly on the MAP sensor bracket by using the mounting bolt and applying 9 N.m (80 lb in) torque. Use the two bolts to mount the AIR pipe onto the AIR manifold. Tighten them to 9 N.m (80 lb in). The AIR pump exhaust pipe will connect to the AIR combination valve where the pinch clamp installation follows before reconnecting the vacuum hose to the combination valve.
Q: How to replace the Air Inject Check Valve on Bank 1 on Buick Rendezvous?
A: The replacement of the air shut-off valve on bank 1 starts with turning off ignition and waiting for engine cooling to be safe from burns before beginning work. Start by disconnecting both the air crossover pipe and vacuum line from the shut-off valve and remove its nut and fasteners that connect the valve to the manifold pipe. The shut-off valve needs to be removed from the bracket after initial disassembly. The installation process starts with bracket securing of the shut-off valve before attaching it to the manifold pipe and tightening to 20 n.m (15 lb ft). After installation of the shut-off valve nut tighten it to 10 n.m (89 lb in) level. Reestablish the vacuum line together with the air crossover pipe to the shut-off valve positioning.
