How to replace the underhood fuse box on Chevrolet Impala?

Replacing the underhood electrical center or junction block begins with disconnecting the positive battery cables and the negative Battery Cable from underhood Fuse block terminals. You need to first remove the tape from the wiring harness at the base of the underhood Fuse block then restore the underhood Fuse block clip retainers with a small flat-bladed tool. Start by lifting the Fuse block and wiring harness from the base and follow it up with removing the bolts from the underhood Fuse block base before removing the base from the shock tower. A small flat-bladed tool should be used to detach the underhood Fuse block lower front terminal positive assurance retainers and remove plastic shields protecting Battery Cable and buss bar terminals. First disconnect the buss bar jumper bar bolts before removing it from all Fuse blocks. Users can access buss bar terminal release tabs by first clearing fuses from the Fuse block(s) before applying a terminal releasing tool to extract buss bar(s) downward and outward. You must pull down to remove the Battery Cable and buss bar terminals from the underhood Fuse block(s) after releasing their clip retainers from the underhood Fuse block(s). You should remove both the Fuse block and the lamp wiring harness from the vehicle if needed. To install the underhood Fuse block(s) position both the Battery Cable terminal and buss bar into their resting position until complete insertion is achieved. Afterward, apply sufficient force to the buss bar into the Fuse block(s) until both components are secure together. Next install the underhood Fuse block terminal positive assurance retainers followed by replacement of the previously removed fuses. Secure the buss bar jumper bar with bolts that should be tightened to 9 n.m (80 lb in). Secure the underhood Fuse blocks into base retaining locks and fully press them into place. Use new tape to secure the wiring harness at the underhood Fuse block base before placing the base onto the shock tower then install and tighten its nuts to 9 n.m (80 lb in). The positive battery cables should get connected to the underhood Fuse block by fastening the nuts to a torque of 15 n.m (11 lb ft). Subsequently, install the negative Battery Cable.
