Engine Accessory Drive and SRS Documentation
This document delivers targeted technical coverage for accessory drive systems and supplemental restraint components. Technicians can rely on these exact factory schematics to streamline their daily workshop routine, cutting down on time spent searching for correct component alignments. The accessory drive section maps out serpentine belt routing and idler pulley layouts for the 4.2L, 4.6L, and 5.4L engine variants. Correct belt installation is critical for proper powertrain operation, and this reference provides the exact routing paths needed before any physical repair begins. Moving to interior safety, the manual outlines the entire SRS network. It catalogs the dual-stage airbag modules, the Restraints Control Module (RCM), impact sensors, and seat track position sensors.
Factory Specifications and Safety Data
Proper reassembly relies on exact tolerances. This manual provides the required factory torque values for critical fasteners. Front impact severity sensor bolts and restraints control module bolts must be secured to 12 Nm (9 lb-ft). Front seat cushion pan-to-track nuts require 25 Nm (18 lb-ft). On the drive system side, belt idler pulley bolts on the 4.2L engine demand 55 Nm (41 lb-ft), while the 4.6L and 5.4L variants are specified at 25 Nm (18 lb-ft).
Working on supplemental restraints involves active, high-voltage safety devices. Always ensure system power is fully depleted and strictly follow standard shop safety protocols to prevent accidental airbag deployment or injury during service.
