Catalog PN: GM 11562588 per figure GM00-540 callout 430 — "PLUG,OIL PAN DRN(M12X1.75X25)(W/SEAL)(EXC MAGNET) — Y 6.2W(LS3) (2008-2011). M12x1.75 thread, 25mm long. Includes integral seal washer. Catalog notes (other figures) the O-ring seal is 12616850 (callout 429 of figure GM00-545 — companion piece)." length_mm lifted into the structured field on 2026-06-04 from the GM parts descriptor already quoted above (M12X1.75X25); 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.
