For 1990-2009 cars

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.

1. Install the lower heat shield insulator to the exhaust manifold. Secure the insulator using three bolts.

Tighten
Tighten the lower heat insulator bolts 15 N·m (11 lb ft).

2. Install the following components:

• | The new exhaust manifold gasket

• | The exhaust manifold

3. Secure the manifold using 5 exhaust manifold nuts (1).

Tighten
Tighten the exhaust manifold nuts to 48 N·m (36 lb ft).

4. Install the 5 upper heat insulator. Secure the insulator using 6 bolts.

Tighten
Tighten the upper heat insulator bolts to 15 N·m (11 lb ft).

5. Install 1 bolt (1) to the exhaust manifold support bracket.

Tighten
Tighten the exhaust manifold bracket bolt to 35 N·m (26 lb ft).
