• Q: How to replace the left exhaust manifold on 2002 Cadillac Eldorado?

  A: Residents must first remove the 2 nuts that secure the secondary air tube to the Exhaust Manifold then disconnect the tube section with its gasket that needs to be discarded. You should first remove the front Engine Mount Bracket then raise and support your vehicle. First remove the Oxygen Sensor and then unfasten the 2 bolts between the left Exhaust Manifold and the front Exhaust Manifold pipe. Follow this step by using a tool to remove the left Exhaust Manifold retaining bolts which enables you to extract the left Exhaust Manifold together with its gasket while discarding the gasket usage. Clean the left Exhaust Manifold while removing both the front Exhaust Manifold pipe seal that belongs to the left Exhaust Manifold as well as the Exhaust Manifold flange seal retainer. The installation process starts with placing the retainer along with a new front Exhaust Manifold pipe seal on top of the left Exhaust Manifold. A new Exhaust Manifold Gasket should then be positioned between the left Exhaust Manifold and the left Cylinder Head. Place the left Exhaust Manifold through the front Exhaust Manifold pipe until it reaches the left Cylinder Head before installing left Exhaust Manifold bolts which should be tightened to 25 nm (18 ft. Lbs. You should install the 2 bolts that fasten the left Exhaust Manifold to the front Exhaust Manifold pipe while tightening them to 25 Nm (18 ft. Lbs.). After installing the Oxygen Sensor and front Engine Mount Bracket and lowering the vehicle you must apply the new gasket to the secondary air tube before using 2 nuts to fasten it to the Exhaust Manifold at 12 nm (106 inch lbs.).
