To remove the exhaust manifold, follow similar steps to remove the heater/ventilation inlet air ducting as mentioned earlier. Raise the front of the vehicle and support it on jackstands, remove the engine splash shield and the front axle reinforcement plate/bar bolts. Attach an engine hoist or support fixture to the lifting eye at the front of the cylinder head to take the weight off the engine. Underneath the vehicle, remove the right-hand engine mounting with the support arm. Remove the plastic cover over the injectors by prying out plastic caps and removing screws. Trace back the wiring from the oxygen sensor and remove the nuts/bolts to separate the exhaust pipe from the manifold. Use the engine hoist to raise the engine slightly, then remove the front exhaust manifold and rear exhaust manifold while taking care not to damage the oxygen sensors. Discard the gaskets. For installation, apply anti-seize high-temperature grease to the manifold studs, replace the manifold gaskets, and tighten the manifold nuts to the specified torque. Tighten the front axle reinforcement plate bolts to the specified torque as well.
