Exhaust Manifold Pipe Replacement - Manual Transmission

EXHAUST MANIFOLD PIPE MANUAL TRANSAXLE REPLACEMENT

REMOVAL

CAUTION: MAKE SURE VEHICLE IS PROPERLY SUPPORTED AND SQUARELY POSITIONED ON HOIST.





1. Raise vehicle on hoist.

NOTICE: Do not apply grease or silicone products to the heated oxygen sensor. Do not alter the wiring in any way. The wires carry air reference to the sensor.

2. Remove heated oxygen sensor electrical connector.
3. Remove heated oxygen sensor from heat shield.
4. Remove heated oxygen sensor.





5. Remove nuts that hold exhaust manifold pipe to exhaust manifold.





6. Remove bolts that hold exhaust manifold pipe to exhaust resonator.
7. Remove exhaust manifold pipe from vehicle.

INSTALLATION





1. Position gasket on exhaust manifold pipe.
2. Position exhaust manifold pipe into vehicle.

IMPORTANT: Do not tighten fasteners.

3. Install nuts that hold exhaust manifold pipe to exhaust manifold.





4. Position gasket between exhaust manifold pipe and exhaust resonator.
5. Install bolts that hold exhaust manifold pipe to exhaust resonator.
Torque:
Exhaust Manifold Pipe-to-Resonator Bolts: 20 Nm (15 ft. lbs.)
6. Tighten nuts that hold manifold pipe to exhaust manifold.
Torque:
Exhaust Manifold Pipe-to-Exhaust Manifold Nuts: 30 Nm (22 ft. lbs.)





NOTICE: Always use a pickle-based anti-seize compound (Saturn P/N 21485279 or equivalent) on the threads of the heated oxygen sensor. If the heated oxygen sensor is replaced, do not apply anti-seize to the new sensor. New sensors have anti-seize pre-applied. Never use silicone products. Silicone products will cause damage to heated oxygen sensor.

7. Install heated oxygen sensor.
8. Connect heated oxygen sensor harness connector.
9. Connect heated oxygen sensor harness to heat shield.
10. Lower vehicle from hoist.
11. Start engine and check for exhaust leaks.
