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
• | All fasteners and threaded holes on the engine utilize metric threads. |
• | All M11 cylinder head bolts are the same length and have a common torque/angle
tightening strategy. |
Changed Engine Specifications
Piston pin specifications have been revised.
Disassembly and Assembly Procedure Revisions
• | The piston and pin are to be serviced as an assembly. |
• | All applications use full-floating design piston pins. |
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
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
