To remove the exhaust manifold first unplug the battery and then take the vehicle off the ground on jack stands. Soak the exhaust pipe to manifold studs and nuts with penetrating oil because they are usually severely rusted; then, undo the nuts fastening the exhaust pipe(s) to the manifold(s). If more force is required to break the nuts loose, the nuts can be heated using propane or acetylene torch. Remove the EGR tube connector from the right side manifold and two through bolts of
Engine Mount. Slowly raise the engine with a floor jack to avoid stretching hoses and connections and with great care for the bulk of the wiper module, cooling fan and fuel lines. Should it be necessary, disconnect the lower engine mount on the left side to allow access to all bolts that are used to attach the exhaust manifold to the
Cylinder Head The exhaust manifold(s) bolts to cylinder head(s) are then removed in order to separate the manifold from the cylinder head. For reassembly, inspect the manifold for cracks and be sure that the bolt threads are dry and both have no damage then clean the mating surfaces before replacing. Place the manifold on the head and fit the mounting bolts and as is always recommended use the torque wrench in steps to tighten the bolts from the center and ends. Last of all, turn on the engine and look for signs of exhaust.
