Q: How to Remove and Install the EGR Tube on Buick Century?
A: Begin the exhaust gas recirculation (EGR) pipe servicing process by removing its retaining bolt from the EGR Valve then gently extracting the pipe assembly backward. The egr pipe assembly nut must first be removed from the Exhaust Manifold before extracting the egr pipe. When installing the EGR Valve pipe you should first secure it to the Exhaust Manifold while tightening the egr pipe nut to 25 n.m (18 lb ft). Attach the EGR Valve pipe bolt and secure it at 25 n.m (18 lb ft).
Q: How to replace the EGR Tube inlet pipe on Buick LeSabre?
A: The replacement of the exhaust gas recirculation (EGR) inlet pipe starts with stripping off the EGR Valve and the EGR Valve outlet pipe. First disconnect the EGR Valve inlet pipe mounting bolt from the Exhaust Manifold and then remove the dual components of mounting bolt plus stud from the EGR Valve inlet pipe bracket. Next you need to eliminate the EGR Valve inlet pipe assembly from the operation. Should you install the EGR Valve inlet pipe assembly fit it back in place using the mounting bolt and stud which secure it to the EGR Valve inlet pipe bracket 50 n.m (37 lb ft). To complete installation of the EGR Valve inlet pipe bolt attach it to the Exhaust Manifold narrowing the bolt to 29 n.m (21 lb in). The last step involves reinstalling both the EGR Valve outlet pipe as well as the EGR Valve.
Q: How to replace the EGR Tube inlet on Buick Regal?
A: The process for replacing an exhaust gas recirculation (EGR) inlet pipe requires removal of the EGR Valve together with the secondary air injection (AIR) pump outlet pipe if present. Detach the EGR Valve outlet pipe together with the EGR Valve adapter pipe mounting bolt from the Exhaust Manifold. First detach the mounting bolt along with the stud from the EGR Valve adapter pipe bracket then unlock the EGR Valve adapter pipe assembly . The installation process starts with setting the EGR Valve adapter pipe assembly into its original position. Mount the mounting bolt and the stud onto the EGR Valve adapter pipe bracket by securing them at 50 n.m (37 lb ft). Start by mounting the EGR Valve adapter pipe bolt to the Exhaust Manifold where tightening to 30 n.m (22 lb in) is necessary. Place back the EGR Valve outlet pipe while reinstalling the secondary air injection (AIR) pump outlet pipe if it is applicable. Finally, install the EGR Valve.
