• Q: How to replace the starter motor on 5.3L and 6.0L engines on 2008 Chevrolet Trailblazer?

  A: The replacement of Starter motors in 5.3l and 6.0l engines starts by disconnecting the negative Battery Cable and safely lifting the vehicle. First disconnect the rear steering gear crossmember before removing the transmission oil cooler line bracket bolt through its retaining clips on the wire harness that attaches to the transmission oil cooler line bracket. Start by uninstalling both the right transmission cover bolt and the Starter bolts. First move the Starter toward the vehicle's front before removing both the transmission cover and then the Starter solenoid heat shield. To navigate the Starter past transmission oil cooler lines and engine Oil Pan the tool needs to be both tilted and rotated. To extract the Starter completely unthread the Starter solenoid nut and the Starter lead from the solenoid stud followed by removing the battery positive cable nut and the battery positive cable from the Starter solenoid. During placement set the Starter between the transmission oil cooler lines and the engine Oil Pan before securing the positive cable to the Starter stud with its nut tightened to 9 n.m (80 lb in). Fasten the Starter solenoid lead to the solenoid stud through the Starter solenoid nut which requires a torque setting of 3.4 n.m (30 lb in). Reinstall the Starter solenoid heat shield while moving the Starter forward toward the vehicle's front but place the transmission cover onto the transmission. You must position the Starter correctly onto the engine before applying the Starter bolts whose torque must be set to 50 n.m (37 lb ft). Use 9 n.m (80 lb in) torque to tighten both the right transmission cover bolt and the transmission oil cooler line bracket bolt. After lowering the vehicle return the rear steering gear crossmember into position before installing the wiring harness retaining clips while connecting the negative Battery Cable.
