Notes
Catalog PN: GM 11518632 per figure for Y ALTERNATOR/GENERATOR, callout 3 — "BOLT,GEN BRKT(M10X1.5X70,25.9 THD)(MATPOINT) — Required: 01, Y 6.2W(LS3),7.0E(LS7) (2009-2011). M10x1.5 thread, 70mm long, 25.9mm threaded length, with Matpoint patch (pre-applied thread sealant/locker)." (PN now known; torque still needs sourcing from GM SI service doc.) GM SI "Generator Bracket Bolt" 50 N·m (37 lb·ft) per fastener spec doc 1705600 (Engine Electrical). "Generator" = alternator in GM nomenclature. Catalog PN 11518632 (M10x1.5x70 with Matpoint sealant patch). length_mm lifted into the structured field on 2026-06-04 from the GM parts descriptor already quoted above (M10X1.5X70); 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.
