• Q: How to replace the left exhaust manifold on 2007 Buick Terraza?

  A: The left replacement of Exhaust Manifold requires beginning by removing the air cleaner outlet duct combined with the right engine mount strut bracket and radiator inlet hose and heater hoses from the heater pipes. Secure the Throttle Body by removing all nuts which hold the heater pipes in position then place the pipes aside. You should start by removing the exhaust crossover heat shield bolts and shield after which you should unfasten the exhaust crossover pipe from the left Exhaust Manifold nuts. Finish removal operations with bolt extraction starting from the Exhaust Manifold heat shield then proceeding to heat shield, Exhaust Manifold bolts and eventually removing the Exhaust Manifold joint with its new gasket. A new Exhaust Manifold Gasket should be positioned on the Cylinder Head before installing the Exhaust Manifold. Begin by tightening the Exhaust Manifold bolts to 20 n.m (15 lb ft) and then move to attach and effectively tighten the Exhaust Manifold heat shield bolts with 10 n.m (89 lb in). Install the exhaust crossover pipe to the left Exhaust Manifold nuts before tightening them to 20 n.m (15 lb ft). First connect the heater pipes to their proper position and then fasten heater pipe nuts at the Throttle Body while attaching the hoses. Secure the hose clamps to heater pipes and hose afterward install the exhaust crossover heat shield followed by its installation bolts with 10 n.m (89 lb in) final torque. The installation process concludes with replacing the radiator inlet hose along with the right engine mount strut bracket and the air cleaner outlet duct.
