Steps
- Test the battery voltage
Touch a multimeter's leads to the positive and negative terminals with the engine off (a resting reading of about 12.4 volts or higher is good), then have an assistant hold the leads and start the truck — you should see at least 13.8 volts.
- Remove the old battery
Disconnect the 8mm negative terminal, then the positive terminal, remove the 8mm hold-down bolt and the hold-down, then lift the battery out.
- Install the new battery
Set it on the tray, refit the hold-down and tighten its 8mm bolt, then tighten the positive terminal followed by the negative, both with an 8mm socket.
