Engine Mechanical - 3.6L - Description and Operation: Overhaul GMC Acadia I

Disassembly and Assembly Procedure Revisions

A variety of procedures have been revised based on the design of the LLT engine.

1. Structural front engine cover has one additional bolt and two optional bolts that must be removed before the cover can be separated from the engine.
2. Single belt accessory drive.
3. Plastic thrust rings installed between cam position actuators and camshafts.

Assembling Components

1. Assemble components using only the sealant (or equivalent) that is specified in the service procedure.
2. Sealing surfaces must be clean and free of debris or oil.
3. Specific components such as crankshaft oil seals or valve stem oil seals may require lubrication during assembly.
4. Components requiring lubrication will be identified in the service procedure.
5. Apply only the amount of sealant specified in the service procedure to a component.
6. Do not allow the sealant to enter into any blind threaded holes, as the sealant may prevent the fastener from clamping properly or cause component damage when tightened.
7. Tighten the fasteners to the proper specifications.
