Q: How to replace the Air Inject Check Valve and Pipe on Cadillac Catera?
A: 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.
Q: How to replace the Air Inject Check Valve for Bank 1 on Cadillac DeVille?
A: The first step to replace the bank 1 secondary air injection (AIR) shut-off valve begins with raising the vehicle. Start by raising the vehicle before removing the two nuts holding the outlet pipe to the Exhaust Manifold. Lower the vehicle afterward. Extract the bank 1 intermediate pipe/hose from its position on the bank 1 air shut-off valve after disconnecting it from the valve then eliminate both vacuum lines attached to it. Remove the three engine securing nuts of the bank 1 air outlet pipe's air shut-off valve followed by removing the valve from the outlet pipe. The installation of bank 1 air shut-off valve requires connection of this component with a new gasket to the bank 1 air outlet pipe while strictly following fastener notice in service precautions. Secure the bank 1 air shut-off valve to the engine with three nuts which need to be tightened to 9 n.m (80 lb in). The vacuum lines require reinstallment while returning the bank 1 air intermediate pipe/hose and clamp to connect with the bank 1 air shut-off valve system. Attach the two securing nuts between the bank 1 air outlet pipe and Exhaust Manifold at 9 n.m torque, repeat for the opposite side before dropping the vehicle.
Q: How to replace the Air Inject Check Valve on Cadillac DTS?
A: Separating the fuel injector sight shield serves as the first step for replacement of the Secondary Air Injection Check Valve. Gratis the engine harness electrical connector from operating with the secondary air injection (AIR) check valve. The constant tension clamp should be pinched while the air pipe needs extraction from the air check valve. Start by extracting the exhaust manifold nuts from the air check valve then detach its bolts to successfully remove the air check valve. The exhaust manifold gasket of the air check valve should be discarded before cleaning all gasket sealing surfaces. The installation of a new air check valve with its gasket to exhaust manifold requires proper placement before installing the valve. Use the given air check valve to secure exhaust manifold nuts while applying torque of 9 nm (80 lb in); afterward use the check valve bolts which should reach the same 9 nm (80 lb in) torque value. Shut down and disconnect the battery and then reconnect the engine harness electrical connector to the air check valve before attaching the air pipe to it. Re-install the fuel injector sight shield as the last step.
