How to replace the Air Inject Check Valve and Pipe on Cadillac Catera?

Replacing the secondary air injection (AIR) check valve and pipe begins with disassembly of the air hoses combined with the removal of the check valve and the center air pipe and subsequent detachment of the upper Exhaust Manifold heat shield. The bolt unfastening of the air pipe must be followed by its separation from the Exhaust Manifold through air pipe bank 1 and air pipe bank 2 detachment. Install the new air pipes by placing their gaskets onto the surfaces and clean the Exhaust Manifold thoroughly to achieve proper sealing. The installation requires gm p/n 5613695 anti-seize compound or equivalent on the air pipe nipple to manifold and the bolts along with the air check valve. Apply the Exhaust Manifold bolts to new air pipes of air pipe bank 1 and air pipe bank 2 until the torque reaches 20 n.m (15 lb ft). Begin with reattaching both upper Exhaust Manifold heat shields and then install the center air pipe and the air check valve. Tighten the check valve to 30 n.m (22 lb ft). The completion includes attaching the air hoses while installing fuse clamps along with leakage verification checks.
