New Product Information
The purpose of New Product Information is to highlight important technical 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
No torque or fastener tightening changes from the previous year. Refer to Fastener Tightening Specifications.

Changed Engine Specifications
No changed engine specifications.

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. For a detailed explanation, refer to Strategy Based Diagnosis or Diagnostic Starting Point - Engine Mechanical.

New Special Tools Required
^ A variety of new tools have been developed to assist in engine disassembly, assembly and on-vehicle service. Refer to Special Tools.
^ Angle Meter J 45059 has been developed to provide technicians with a convenient method to tighten bolts that require the torque angle tightening strategy.

A Component Comparison from the Previous Year
^ The exhaust gas recirculation system (EGR) has been removed. Refer to Disassembled Views.
^ The front cover is now aligned to the engine block with 2 front cover locating pins.
^ All applications use a full-floating design piston and pin assembly.
