Caution: Ensure that the vehicle is properly supported and squarely positioned. To help avoid personal injury when a vehicle is on a hoist, provide additional support for the vehicle on the opposite end from which the components are being removed.

Notice: Excessive flexing of the exhaust pipe may damage the flex coupling. Limit flexing to 12 degrees.

1. Raise the vehicle on hoist.

Important: Do not apply silicon products to the oxygen sensor.

2. Disconnect the electrical connector from the oxygen sensor (O2S).



3. Remove the nuts (3) from the exhaust pipe flange to intermediate pipe and separate the flange from the studs.



4. Remove the nuts (3) from the exhaust pipe flange to exhaust manifold.



5. Separate the hanger from the rubber isolator.
6. Separate the pipe flange from the manifold studs and remove the exhaust pipe.
7. Fully remove and discard used gaskets.
8. Remove the oxygen sensor if transferring to a new exhaust pipe.

1. Install a new gasket onto the exhaust manifold studs.
2. Assemble the exhaust pipe to manifold. Install new nuts and tighten.

Tighten
Tighten the exhaust manifold pipe-to-exhaust manifold nuts - 4-CYL to 42 N·m (31 lb ft).




3. Install the new gasket onto the exhaust pipe flange.
4. Assemble the exhaust pipe to intermediate pipe. Install new nuts and tighten.

Tighten
Tighten the exhaust pipe-to-intermediate pipe nuts - 4-CYL to 30 N·m (22 lb ft).
