2000 Cadillac Seville Exhaust Manifold Parts Questions & Experts Answers

• Q: How to replace the right exhaust manifold on 2000 Cadillac Seville?

  A: A proper replacement of the right Exhaust Manifold starts by taking out the Oxygen Sensor followed by vehicle elevation and support. First disconnect the nuts between the air tube and the Exhaust Manifold then take out the exhaust front pipe. The procedure requires users to detach the real-time dampening sensor links from both lower control arms and intermediate shaft from steering gear. Mount a high screw jack under the rear engine cradle back member to support it before removing the four cradle-to-body bolts that extend toward the back and allowing the engine cradle to drop. Start by taking out the right side Cylinder Head to the transaxle brace followed by removing Exhaust Manifold nuts that need an open-end wrench or universal coupling tools for proper access. First eliminate the manifold from its position and dispose of the gasket before performing a thorough cleaning procedure of the Exhaust Manifold for inspection. Position the new manifold gasket on Cylinder Head studs before installing both the manifold and its nuts while tightening the bolts to 25 nm (18 ft. Lbs.). Fit the right side Cylinder Head to the transaxle brace followed by Exhaust Manifold nut installation at 47 nm (35 ft. Lbs.). Position the engine cradle correctly then install the four rearward cradle-to-body bolts and tighten them to 191 nm (141 ft. Lbs.). Wipe away the screw jack and join the intermediate shaft with the steering gear works followed by tightening the pinch bolt to 47 nm (35 ft. Lbs.). The real-time dampening sensor links should be reconnected to the lower control arms before implementing the exhaust front pipe and applying the new gasket to the air tube. After fixing the new gasket to the air tube take on the manifold nuts for tightening at 12 nm (106 inch lbs.) and lower the vehicle before reinstalling the Oxygen Sensor.
