How to replace the Air Inject Check Valve on 2002 Buick LeSabre?

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.
