  Q: How to replace the negative battery cable on Chevrolet Avalanche 1500?

  A:

  Start by disconnecting the negative Battery Cable before you replace it. Your task involves removing the Battery Cable bracket bolt and bracket from the Power Steering Pump and disconnecting the accessory power fuse block front wiring harness electrical connector that attaches to the negative cable connector on vehicles using 4.8l, 5.3l, or 6.0l engines. For engine types with 4.8l, 5.3l or 6.0l engine capacity you should first detach the negative cable clip from the positive cable clip before vehicle support and suspension. The engine wiring harness ground/negative cable bolt must be removed besides the additional removal of the negative cable clip from the positive cable clip when working on vehicles featuring an 8.1l engine. After lifting the vehicle to its upright position install the engine wiring harness ground/negative cable bolt then place wiring harness ground and negative cables correctly prior to removing the forward lamp wiring harness ground/negative cable bolt and the negative Battery Cable. Install the negative Battery Cable first by attaching the negative cable and forward lamp wiring harness ring terminals to the frame and inserting the anti-rotation tab on the forward lamp wiring harness into the frame hole. Fasten the forward lamp wiring harness ground/negative cable bolt with a torque of 9 n.m (80 lb in). Position the wiring harness ground and negative cables for engines with an 8.1l by correctly locating the anti-rotation tab on the negative cable before tightening the engine wiring harness ground/negative cable bolt to 25 n.m (18 lb ft). After lowering the vehicle position the positive cable clip on top of the negative cable clip. Place the negative cable and engine wiring harness ring terminals onto the engine block while ensuring correct placement of the anti-rotation tab on the negative cable next install the engine wiring harness ground/negative cable bolt and tighten it to 25 n.m (18 lb ft). Proceed with the following installation steps: first lower the vehicle then connect the accessory power fuse block front wiring harness electrical connector to the negative cable connector if equipped then install Battery Cable bracket and Power Steering Pump bolt with a torque of 25 n.m (18 lb ft). Complete the process by attaching the negative Battery Cable.

  Q: How to remove and install the positive battery cable on Chevrolet Avalanche 1500?

  A:

  The procedure to disconnect the positive Battery Cable starts with negative cable removal followed by unsnapping the positive cable cap before disconnecting the positive cable. Remove the positive Battery Cable bolt from the underhood bussed electrical center (UBEC) while remembering that the bolt stays with the cable due to its integral design. First remove any necessary engine sight shield components before releasing the junction block cover to take the positive Battery Cable from its junction block mounting. Car models with 4.8l, 5.3l or 6.0l engines require the removal of the negative cable clip from the positive cable clip followed by vehicle elevation and support and for vehicles equipped with an 8.1l engine, both negative and positive clips need to be removed. The first step includes removing the channel bolt securing the positive Battery Cable before slipping the channel pin from the Oil Pan tab and extracting the cable from the channel. A technician must first remove the Battery Cable bracket bolt and bracket from the Power Steering Pump before moving on to remove the positive cable nut and positive cable from the Starter when working with 4.8l, 5.3l or 6.0l engines. Apply tools to detach the positive cable clip from the Oil Pan and then the positive Battery Cable. The installation requires 8.1l engine technicians to first remove both the positive cable nut and the positive cable from the Starter before moving to the positive cable clip bolt and positive cable from the engine harness clip. The positive Battery Cable installation for 8.1l motors begins with the cable itself then proceeds to the engine harness clip attachment. Fitting and securing the positive cable clip bolt should be performed until it reaches 8 n.m torque (71 lb in) while the subsequent positive cable installation to the Starter requires a torque on the positive cable nut set to 9 n.m (80 lb in). The positive Battery Cable installation process requires first coupling the cable to the Oil Pan clip before affixing it to the Starter where the positive cable nut needs a tightening torque of 9 n.m (80 lb in). Install the Battery Cable bracket then mount its bolt to the Power Steering Pump where tightening should reach 25 n.m (18 lb ft). Screw in the positive Battery Cable while setting it into the channel before sliding the channel pin to the Oil Pan tab and finishing with the positive Battery Cable channel bolt installation at 12 n.m (106 lb in). Vehicle position must be lowered while installers should fasten negative cable clips to positive cable clips when working on 8.1l engines as well as on 4.8l, 5.3l, and 6.0l engines. The positive Battery Cable should be inserted into the junction block and then install the junction block cover while optional engine sight shield reattachment may be required. The positive cable bolt at the ubec requires 9 n.m (80 lb in) torque before the positive Battery Cable installation with a torque of 17 n.m (13 lb ft) and final closure of both positive Battery Cable caps and negative Battery Cable application.
