Battery Cable

The battery negative cable extension cable replacement starts with disconnecting the negative Battery Cable. Pull the engine wiring harness from its mounting position on the battery negative cable extension cable clip then remove the battery negative cable extension cable ground bolt attached to the Cylinder Head. Detach the battery negative cable extension cable terminal from the Cylinder Head before removing the battery negative cable extension cable ground bolt from the left wheelhouse panel upper reinforcement. The engine compartment becomes accessible after disconnecting the battery negative cable extension cable clip from both the left upper engine compartment support bracket and the front compartment side rail. Reinstall the battery negative cable extension cable inside the engine compartment while following the fastener notice during the process. Connect the battery negative cable extension cable ground bolt to the left wheelhouse panel upper reinforcement. Tighten the bolt to 58 n.m (43 lb ft). Connect the left upper engine compartment support bracket and front compartment side rail through the battery negative cable extension cable clips. Screw in the battery negative cable extension cable terminal to the Cylinder Head then install the ground bolt on the extension cable while tightening it to 58 n.m (43 lb ft). Connect the engine wiring harness to the battery negative cable extension cable clip and join the negative Battery Cable into place.

The first step to replace the battery positive junction block cable requires disconnecting the negative Battery Cable. Then proceed to open the accessory wiring junction block cover after which you must remove the accessory wiring junction block nut. Unhook both the positive Battery Cable terminal from its stud as well as the battery positive junction block cable terminal from its stud. Unfasten the battery positive junction block cable clips which are attached to the power steering reservoir bracket and move the battery positive junction block cable boot to a new position. To proceed with the removal disconnect the battery positive junction block cable to generator nut while also deinstalling the battery positive junction block cable terminal from its generator stud. The technical intervention begins by taking away the left Catalytic Converter along with the starter heat shield bolt coupled with shield and the battery positive junction block cable clip which remains on the engine block. Lower the vehicle while removing the battery positive junction block cable after first detaching both the starter solenoid bat terminal nut and the battery positive junction block cable terminal from the starter. The vehicle receives the battery positive junction block cable before installing its terminal at the stud and its positive Battery Cable terminal at the junction block stud. The accessory wiring junction block nut requires tightening to 22 n.m (16 lb ft) then you should install the accessory wiring junction block cover . After the power steering reservoir bracket installment of the battery positive junction block cable clips the following step includes connecting the generator stud to the battery positive junction block cable terminal before securing the battery positive junction block cable to generator nut with a torque of 22 n.m (16 lb ft). Position the battery positive junction block cable boot and raise the vehicle while using proper support so you can install the battery positive junction block cable terminal to the starter and the starter solenoid bat terminal nut before tightening it to 25 n.m (18 lb ft). Position the battery positive junction block cable clip to engine block and ground first before securing it to starter heat shield with a bolt at 7 n.m (62 lb in) torque while additionally attaching it to the left Catalytic Converter. The last step is to connect the negative Battery Cable.

Position the battery negative cable extension cable terminal to the cylinder head, install the ground bolt, reconnect the engine wiring harness, reinstall the air cleaner assembly, and finally connect the negative battery cable.

After that, remove the negative battery cable.

Connect the body wiring harness electrical connector to the battery cable electrical connector and install the positive battery cable to the body wiring harness right front sill plate.
