4 Major Service Operations
ATTENTION
The V6 engine is a combination of numerous components, containing machined, honed, polished and lapped
surfaces manufactured on the latest, high technology production equipment. Many of the components
contain tolerances measured in thousandths of a millimetre. Consequently, when any engine component is to
be serviced, care and cleanliness are extremely important.
Prior to re-assembly of the V6 engine, all components must be cleaned and inspected in accordance with the
relevant procedures throughout this section, and replaced or repaired where required.
In addition to cleaning and inspecting components, a liberal coating of engine oil should be applied to friction
surfaces during assembly to protect and lubricate the surfaces on initial operation.
When performing any service operation contained in this Section, it should be understood that correct
cleaning and protection of machined surfaces and friction areas is part of the repair procedure. This is
considered standard workshop practice, even if not specifically stated. Torque values must be used as
specified during reassembly to ensure correct retention of all components.
Through out this section, fastener torque wrench specifications may be accompanied with the following
identification marks:
■ Fasteners must be replaced after loosening.

Fasteners either have micro encapsulated sealant applied or incorporate a mechanical thread lock and
should only be re-used once. If in doubt, replacement is recommended.

If one of these identification marks is present alongside a fastener torque wrench specification, the
recommendation regarding that fastener must be adhered to.
4.1 Engine Removal
CAUTION
• Allow the engine to cool to at least 50 °
°°
°
C,
before attempting fastener removal.
• As aluminium has a greater rate of thermal
expansion than that of cast iron,
aluminium bolt hole threads will change
dimension to a larger extent than cast iron
bolt threads.
• If a bolt or other threaded component is
removed before the engine is allowed to
cool to at least 50 °
°°
°
C, threads could be
pulled from the cylinder block or cylinder
head.
• Do not use impact tools to remove bolts
during engine disassembly. While this may
be common practice with cast iron engine
components, use of these tools is likely to
pull the aluminium threads in the cylinder
block or head of this engine.
