• Q: How to replace the Air Inject Check Valve on Bank 1 on 2001 Chevrolet Lumina?

  A: The procedure for bank 1 Air Inject Check Valve/pipe replacement begins with unfastening the Air Hose clamp then removing clamp and Air Hose from the check valve before separating the vacuum hose from the check valve. Separate the manual.adapter stud from its nut before you disconnect the exhaust manifold adaptors from the air pipe. Start by removing the check valve/pipe unit from both the manifold and bracket stud before disconnecting its bottom two bolts to divide the pieces. Reinstallation occurs when you pass the two pipe attachment screws through both sides of the check valve before attaching the spring clamp to unite the check valve and reactor pipe while locking the pipe with a nut to a torque of 10 nm (89 lb in). Position the check valve/pipe assembly onto its brackets while securing it through manifold adaptors and tighten the pipe to them before relocking the bracket stud at 10 nm (89 lb in). Last, connect the vacuum hose toward the check valve before attaching the Air Hose with clamp over the check valve and tightening the clamp.
