• Q: How to replace the left exhaust manifold on 2001 Cadillac Eldorado?

  A: You should begin left Exhaust Manifold replacement by unfastening the two nuts that keep the secondary air tube connected to the manifold. Then remove the tube and its gasket which need replacing. First raise the vehicle after removing the front Engine Mount Bracket for better access. The required step is to disconnect the Oxygen Sensor before proceeding. The next step is to remove the two bolts which connect the left Exhaust Manifold to the front Exhaust Manifold pipe and then proceed with the left Exhaust Manifold retaining bolts. Detach the left Exhaust Manifold and its gasket by removing it from the engine while disposing of the gasket and discarding the front Exhaust Manifold pipe seal from the left Exhaust Manifold. Use proper cleaning methods on the left Exhaust Manifold after removing its Exhaust Manifold flange seal retainer. Reposition the retainer beneath a new front Exhaust Manifold pipe seal situated on top of the left Exhaust Manifold before setting a new Exhaust Manifold gasket between the left Exhaust Manifold and the left Cylinder Head. Put the left Exhaust Manifold into the front Exhaust Manifold pipe while driving it toward the left Cylinder Head but follow the provided fastener instructions. Fasten the left Exhaust Manifold bolts with a torque of 25 nm (18 ft. Lbs.). Afterwards, attach two bolts that link the left Exhaust Manifold to the front Exhaust Manifold pipe while tightening them to a torque of 25 nm (18 ft. Lbs.). The vehicle must be lowered after reattaching the front Engine Mount Bracket and Oxygen Sensor while installation of a new gasket to the secondary air tube precedes attaching the secondary air tube to the Exhaust Manifold with two nuts tightened to 12 nm (106 inch lbs.).
