Exhaust Manifold — RH

Removal

NOTICE: Whenever turbocharger air intake system components are removed, always cover open ports to protect from debris. It is important that no foreign material enter the system. The turbocharger compressor vanes are susceptible to damage from even small particles. All components should be inspected and cleaned, if necessary, prior to installation or reassembly.

1. Remove the RH turbocharger. For additional information, refer to Section 303-04C .

2. Remove the 8 nuts and the RH exhaust manifold.
   • Discard the nuts and exhaust manifold gasket.

3. Clean and inspect the RH exhaust manifold. For additional information, refer to Section 303-00 .

4. Remove and discard the 8 RH exhaust manifold studs.

5. NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These may cause scratches and gouges resulting in leak paths. Use a plastic scraper to clean the sealing surfaces.

   Clean the exhaust manifold mating surface of the cylinder head with metal surface prep. Follow the directions on the packaging.

Installation

1. Install 8 new RH exhaust manifold studs.
   • Tighten to 12 Nm (106 lb-in).

2. NOTICE: Failure to tighten the exhaust manifold nuts to specification a second time will cause the exhaust manifold to develop an exhaust leak.
