2003 Pontiac Montana battery removal

Before disconnecting the battery, make sure the radio is turned off. If left on, the radio will ask you for the radio code to have it work again.

You have to remove the round bar on the passenger side. There are two bolts in front and one in the back by hood hinge. The round bar slides out of the relay box.
Remove the wire connecting to the relay box to the battery by removing the holding nut. Lay the relay box over - towards the motor.
Remove the hold-down bolt located on the backside of the battery at the bottom.
Remove the batter posts bolts. Remove old battery.
Put new battery in and reverse the above steps.
