The purpose of New Product Information is to highlight, or indicate, important product changes from the previous model year.
Changes may include 1 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 LH6 engines utilize metric threads. |
| • | Certain fasteners should not be used again. Bolts, studs, or other fasteners that must be replaced, will be called out in the specific service procedure. |
| • | Some applications may use a second design camshaft retainer plate and bolts. Refer to
Camshaft Installation. |
New Sealants and/or Adhesives
Sealers and adhesives, as required, are identified within the specific service procedures. Refer to
Adhesives, Fluids, Lubricants, and Sealers.
Disassembly and Assembly Procedure Revisions
The piston and piston pin are to be serviced as an assembly.
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 condition. 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
No new special tools have been designed for this application.
A Component Comparison from the Previous Year
Some applications may use a second design camshaft retainer plate and bolts. Refer to
Camshaft Installation.
