Notes

Catalog PN: GM 12554990 per figure GM00-540 callout 453 — "BOLT,OIL PAN(REAR POSITIONS)(M6X1.0X136) — Required: 02, Y 6.2W(LS3) (2008-2011). M6x1.0 thread, 136mm long. The two rear-most oil pan bolts that thread up through the pan rail into the block." length_mm lifted into the structured field on 2026-06-04 from the GM parts descriptor already quoted above (M6X1.0X136); the third number is the bolt length in mm. Cross-checked against the chevrolet-parts-canada parts catalog (captured 2026-05-28), whose blocked detail pages and callout-only diagrams do not separately state this length, so the value rests on the GM Professional Parts Catalog descriptor.
