• Q: How to replace the EGR Tube inlet pipe on 2003 Buick Park Avenue?

  A: The correct replacement process for the exhaust gas recirculation (EGR) inlet pipe requires beginning with EGR Valve removal followed by removal of the EGR Valve outlet pipe. Begin by taking out the EGR Valve inlet pipe mounting bolt from the Exhaust Manifold before removing both the mounting bolt and stud from the EGR Valve inlet pipe bracket. The EGR Valve inlet pipe assembly will need removal as the next step. Putting the EGR Valve inlet pipe assembly back in position starts your installation steps and you must use the mounting bolt and the stud to fix it onto the EGR Valve inlet pipe bracket while tightening them to 50 n.m (37 lb ft). Proceed with mounting the EGR Valve inlet pipe bolt into the Exhaust Manifold while tightening it to 29 n.m (21 lb in). You should reinstall the EGR Valve outlet pipe together with the EGR Valve.
