MANIFOLD-EXHAUST-RIGHT
REMOVAL
1. Disconnect battery negative cable.
2. Separate the exhaust pipe at the exhaust manifold.
3. Remove the air cleaner hose (1) and housing.
4. Disconnect the TPS, IAC and purge vacuum hose from the throttle body.
5. Disconnect the spark plug wires at the spark plugs.
6. Disconnect the oxygen sensors (1,2).
7. Remove bolts attaching exhaust manifold to cylinder head and remove manifold.
8. Inspect and clean manifold.
CLEANING
1. Discard gasket (if equipped) and clean all surfaces of manifold and cylinder head.
INSPECTION
Inspect exhaust manifolds for damage or cracks and check distortion of the cylinder head mounting surface and exhaust crossover mounting surface with a straightedge and thickness gauge.
Manifold surface flatness limits should not exceed 1.0 mm (0.039 in.).
INSTALLATION
1. Position exhaust manifold on cylinder head and install bolts to center runner (cylinder # 3) and initial tighten to 2.8 N·m (25 in. lbs.).
2. Install the remaining manifold attaching bolts. Tighten all bolts to 23 N·m (200 in. lbs.).
3. Connect the oxygen sensors (1,2).
4. Connect the spark plug wires to the spark plugs.
5. Connect the IAC,TPS and the EVAP hose to the throttle body.
6. Attach exhaust pipe to exhaust manifold.
7. Install the air cleaner housing and hose (1).
8. Connect battery negative cable.
