Notes

Catalog PN: GM 11610787 per figure for Y STARTER MOTOR, callout 2 — "BOLT,STRTR(OUTBOARD)(M10X1.5X116)(ACDelco #11610787) — Required: AR (as required), Y 6.2W(LS3) (2008-2011). M10x1.5 thread, 116mm long. The outboard starter mounting bolt (two used per starter, this is the long-shank bolt; the inboard bolt is shorter)." (PN now known; torque still needs sourcing from GM SI service doc.) GM SI "Starter Motor Bolt" 50 N·m (37 lb·ft) per fastener spec doc 1705600 (Engine Electrical). Two bolts per starter; the long outboard bolt 11610787 (M10x1.5x116) was identified via the 2011 parts catalog. length_mm lifted into the structured field on 2026-06-04 from the GM parts descriptor already quoted above (M10X1.5X116); 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.
