Notes

GM "BOLT,BAT NEG CBL GND(M8X1.25X31)" callout 4 of figure 1Y02-079 (Y07-67 Battery Cables & Related Parts, LS3) in the 2011 GM Professional Parts Catalog. M8x1.25 thread, 31mm long. Fitment "Y (2006-2011)". Torque value not in parts catalog — typical GM M8 ground-stud torque is 10-15 N·m (90-130 lb·in); confirm against GM SI Fastener Specifications doc 2296270 before relying on it. GM SI "Battery Positive/Negative Cable Ground Bolt (at engine)" 40 N·m (30 lb·ft) per fastener spec doc 1705600 (Engine Electrical). The engine-side ground bolt for the combined POS+NEG cable harness 20835504. A second ground bolt at the frame rail uses 25 N·m (18 lb·ft). Catalog PN 11589258 (M8x1.25x31). length_mm lifted into the structured field on 2026-06-04 from the GM parts descriptor already quoted above (M8X1.25X31); 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.
