2B-6 Chapter 2 Part B V6 engine 5.8 Exhaust manifold-to-exhaust system joint (upper arrow) and cross-over pipe (lower arrow) to remove the rear manifold heat shield, dis- To make removal easier, apply penetrat- ing oil to the exhaust manifold and manifold- to-pipe fasteners. 5 Working under the vehicle, remove the exhaust manifold cross-over pipe. Disconnect the oxygen sensor wiring harness at the connector. If you are removing the rear exhaust manifold (near the firewall), remove the power If you are removing the rear exhaust manifold (near the firewall), detach the illus- tration). Note: It may be necessary to tem to facilitate rear manifold removal (see 9 Unscrew the mounting nuts, remove the exhaust manifold and gasket (see illustra- 10 Using a wire brush, clean the exhaust manifold studs, replacing any that show thread damage. 11 Using a scraper, remove all traces of gasket material from the exhaust manifold, 12 Using a precision straightedge and feeler gauge, check the exhaust manifold Installation 13 Install the new exhaust gasket(s) onto 5.9 Exhaust manifold mounting nuts (arrows) (front manifold shown, heat shield removed) 6.4a To keep the crankshaft from turning, insert a large screwdriver or bar through the opening in the damper/pulley and wedge it against the engine block, then loosen the bolt with a socket and breaker bar the cylinder head. Apply Loctite No. 271 to the exhaust manifold mounting stud threads. The remaining installation steps are the reverse of removal. Install a new gasket(s) Run the engine and check for exhaust leaks. 6 Timing belt - removal, inspection Caution: If the timing belt failed with the have occurred.
