Notes
Catalog PN: GM 11515768 per figure 1Y01-037 callout 2 — "BOLT — generic GM hex-flange bolt used to secure the accessory drive belt tensioner (12569301) to the engine front. Figure 1Y01-037 (Y Pulleys & Belts/Accessory Drive, LS3/LS7), $0.85 list price (small fastener)." (PN now known; torque still needs sourcing from GM SI service doc.) Drive Belt Tensioner Bolts 50 N·m (37 lb·ft). Sourced from GM SI fastener spec doc 2054937 (6.2L LS9 Engine Mechanical) because the LS3 fastener spec doc 2296270 does not list this entry explicitly. The LS3 (figure 1Y01-037) and LS7 share the same drive belt tensioner 12569301 and M10 mounting hardware, so the LS9 torque is treated as applicable.
