New Product Information for GMC Truck Savana 2007

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 engine utilize metric threads.

•	All M11 cylinder head bolts are the same length and have a common torque/angle tightening strategy.

•	Some applications may use a second design camshaft retainer plate and bolts. Refer to Camshaft Installation .

•	The torque value for the oil pressure sensor has been revised. Refer to Engine Mechanical Specifications.

New Sealants and/or Adhesives

•	Sealers and adhesives, as required, are identified within the specific service procedures. Refer to Adhesives, Fluids, Lubricants, and Sealers.

•	A new sealer has been identified for the oil pan to front cover and oil pan to rear housing sealing surfaces.

Disassembly and Assembly Procedure Revisions

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 condition. 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

Oil pressure gage adapter EN-47971 is required for oil pressure testing. The new design oil filter with internal bypass valve has a larger diameter oil filter fitting. Refer to Special Tools.

A Component Comparison from the Previous Year

•	All M11 cylinder head bolts are the same length.

•	All applications use full-floating design piston pins.

•	Some applications may use a second design camshaft retainer plate and bolts. Refer to Camshaft Installation .

•	The oil filter bypass valve is now internal to the oil filter.

•	An electronically actuated drive-by-wire throttle body replaces the cable actuated design.
