Notes

If equipped. Catalog PN: GM 11516697 per figure for Y POWER STEERING PUMP, callout 10 — "BOLT,P/S PUMP(M8X1.25X84MM) — Required: 02 per pump, Y (2005-2011). M8x1.25 thread, 84mm long." (PN now known; torque still needs sourcing from GM SI service doc.) GM SI "Power Steering Pump Bolt (LS3, LS7)" 25 N·m (18 lb·ft) per fastener spec doc 2497908 (Power Steering). LS9 uses higher torque (50 N·m) because of different pump and mounting design. Catalog PN 11516697 (M8x1.25x84mm). length_mm lifted into the structured field on 2026-06-04 from the GM parts descriptor already quoted above (M8X1.25X84); 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.
