  Q: How to remove and install the exhaust manifold on Nissan Murano?

  A: This procedure is for manual transmission cars only because for the exhaust manifolds in automatic transmission cars the engine has to be pulled out. First, be sure to lift the car and support it on jackstands; next, unbolt the front portion of the exhaust pipe. If the rear exhaust manifold, or the catalyst is removed, slightly raise the rear section of the engine/transaxle assembly and remove the rear engine mounting bracket insulator and the cowl cover. Second, you have to take out the upstream and downstream oxygen sensors and thereafter unbolt the exhaust manifold and the catalyst heat shields. Remove the exhaust manifold from the catalyst by using the factory tool, by Loosening the bolt and nut holds the catalyst to the manifold. Loosen and take out the exhaust manifold nuts in precisely the opposite sequence in which they were tightened and then replace the exhaust manifold. Scrape off the entire old gasket materials, and carbon on the mating surfaces of the manifold and Cylinder Head. For inspection, utilize the precision straightedge and the feeler gauge to first determine the flatness of the exhaust manifold sealing surface against the maximum allowable measure; in case of excessive warpage, replace the manifold or have it surfaced. For replacement, slide the new exhaust manifold gaskets over the studs on the cylinder head and thread the manifold and its nuts/bolts and tighten in a progressive manner to the recommended torque. Last of all, reattach the other components in the sequence they were detached from and charge the battery as well as doing the required re-learn operations.
