Start by removing the bolts from the collective and setting them aside. Loosen the collector and remove the bolts holding the manifold on, then remove the manifold from the vehicle. Install your new manifold in the same spot the old manifold was in and reattach the bolts. Clean all the other parts and hardware you removed, then reinstall these parts in the reverse order that you removed them. Make sure all bolts are tight, and your Jeep Cherokee exhaust manifold replacement is complete.
