2000 Cadillac Catera Exhaust Manifold Parts Questions & Experts Answers

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

  A: The right Exhaust Manifold replacement process requires developers to start by taking out the transmission and coolant intake pipe before removing lower heat shield bolts one by three and finally removing the lower heat shield itself. The Exhaust Manifold replacement sequence starts with taking off three nuts on its rear section and the rear upper heat shield bolt and catalytic converter fasteners. Lower the vehicle while you remove the accessory drive belt tensioner followed by the two nuts near the front of the Exhaust Manifold. You need to remove the upper heat shield bolts to reach the air pipe before detaching the air pipe bolts as well as the air pipe from the Exhaust Manifold. To remove the Exhaust Manifold begin by first taking off the two upper nuts and subsequently raising the vehicle to extract it beneath. Begin by cleaning both Cylinder Head and Exhaust Manifold mating areas if you plan to reuse them before putting on the Exhaust Manifold and applying torque to its most accessible nuts. Lower the vehicle before installing the two upper nuts on the Exhaust Manifold while applying a torque of 20 nm (15 ft lbs) to them. Before installing and tightening the air pipe bolts at the Exhaust Manifold, coat them with high temperature anti-seize compound, gm p/n 12371386 or equivalent. Apply the compound to the bolts before securing them to 20 nm (15 ft. Lbs.). The anti-seize compound should be applied to the upper heat shield bolts before installation and subsequent tightening to 8 nm (71 inch lbs.). Attach the accessory drive belt tensioner next before installing the two lower nuts at the front of the Exhaust Manifold to a torque of 20 nm (15 ft. Lbs.). Raise the vehicle while you install the catalytic converter nuts and apply torque evenly to 20 nm (15 ft. Lbs.). The three lower nuts at the Exhaust Manifold rear need an identical torque fitting of 20 nm (15 ft. Lbs.). Place the lower heat shield before applying high temperature anti-seize compound to its bolts and torque them to 8 nm (71 inch lbs.). Complete the task by lowering the vehicle then replace the coolant intake pipe followed by the Transmission Assembly.
