### Installation Procedure

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Important: When installing a new exhaust system component, always use new gaskets and seals.

1. Install the exhaust manifold with a new gasket.

Tighten
Tighten the manifold nuts and bolts (1) to 30 N·m (21.5 lb ft).

2. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
3. Install the exhaust manifold reinforcement bracket following to the exhaust manifold and engine block.

Tighten

• | Tighten the engine mount-to-exhaust bracket bolt (1) to 54 N·m (40 lb ft).

• | Tighten the exhaust bracket-to-exhaust manifold nut (2) to 50 N·m (37 lb ft).

4. Install the front pipe. Refer to Front Pipe Replacement .
5. Lower the vehicle.
6. Install the exhaust manifold cover (2) and the cover bolts (1).

Tighten
Tighten the exhaust manifold heat shield bolts to 10 N·m (89 lb in).

7. Install the oil dipstick and tube (3) using a new O-ring.
8. Attach the oxygen sensor couplers to the mounting bracket (1) and connect the oxygen sensor (HO2S1) electrical connectors (2).
