Tightening procedure
GM does not publish a discrete torque value for this item in the fastener specifications. See the notes below for how it is serviced.
Notes
The LS3 water pump pulley is press-fit onto the water pump shaft — there is no bolt-on pulley with its own torque spec. The water pump (19180610) is sold as a complete assembly including the pulley. This entry does not apply to the LS3 platform; it is retained only if the dataset is reused for older small-block-Chevy V8 engines that did use bolt-on pulleys.
