New Product Information

The purpose of New Product Information is to highlight or indicate important product changes from the previous model year.
Changes may include one or more of the following items:
- Torque values and/or fastener tightening strategies
- Changed engine specifications
- New sealants and/or adhesives
- Disassembly and assembly procedure revisions
- Engine mechanical diagnostic procedure revisions
- New special tools required
- A component comparison from the previous year

Torque Values and/or Fastener Tightening Strategies
- The new service thread repair tools and service procedures are identified.
- A second design connecting rod bolt may be used. The proper fastener tightening value MUST be used with the correct bolt.

New Sealants and/or Adhesives
No sealant or adhesive changes from the previous year.

Engine Mechanical Diagnostic Procedure Revisions
All diagnosis on a vehicle should follow a logical process. Strategy based diagnostics is a uniform approach for repairing all systems. The diagnostic flow may always be used in order to resolve a system problem. The diagnostic flow is the place to start when repairs are necessary.

New Special Tools Required
- The proper thread repair procedures for aluminum cylinder blocks and cylinder heads have been added.
- J 42078 is not required for installation of the second design seal and shim assembly.

A Component Comparison from the Previous Year
- The engine coolant air bleed system has been changed to a two point system with the coolant air bleed pipe mounted to the front top area of both cylinder heads.
- Valve lift specifications are changed.
- The Exhaust Gas Recirculation (EGR) system has been deleted.
- Crankshaft main bearing clearances are reduced.
- A second design valve stem oil seal and shim assembly may be used on later engines.
