IMPORTANT
All fasteners are important attaching parts as they affect the performance of vital components and / or could
result in major repair expense. Where specified in this section, fasteners MUST be replaced with parts of the
same part number or a GM approved equivalent. Do not use fasteners of an inferior quality or substitute
design.
Torque values must be used as specified during reassembly to ensure proper 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.
&
&&
& Vehicle must be at kerb height before final tightening.
6
66
6 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.
