Yes you do need to remove the brace "bar" above the battery. If I am not mistaken, the fuse box also has to be relocated for clearance. One thing you must do before you start is disconnect the negative cable from the battery. The negative cable is the black one. One of the oldest rules when working on any vehicle battery is negative is disconnected first and reconnected last. Since the vehicle is "negative ground" it will make it impossible to short negative to ground. The bolts that hold the bar in place are either 13mm or 15mm. The battery is held in place with a plastic wedge that is held down with a 13mm bolt. The battery cables are 8mm.

2005 Avalon, I changed the dead battery and think the cables touched. Now it won't turn over. The push button start goes green but the car doesn't engage anything to start. Thoughts?

Hello, check the large fuses in the fuse box under the hood, there is a 140 alternator fuse which is larger than the rest, it may be blown due to the short circuit, some models use an integrated fusible link assembly, these are about 1/4" wide and about 3" long and have either a blue or brown top, both versions are bolted in on the inside of the box, in some cases the sub fuse holder can be released from the box and pulled up enough so that you can remove the bolts.

How do I get the battery out of a 2005 Pointiac Montana?

It's a tight fit. You must remove the bolts securing the bar that goes from the radiator support to the strut tower and remove the bar. The underhood fuse block (also known as battery juction box) can "uncliped" from its base and can then be moved aside. Then the battery has to be turned up on end to get it out.

...and people cannot understand why we mechanics would charge for something as simple as replacing a battery......:-D

How do you get fuse box off bar to remove battery

brasssyslv, There are three bolts holding the bar in place. Two in front and one in the back. To get at the back bolt, remove the plastic triangle shaped cover by pulling it straight up. When you remove these bolts, grab the bar and turn it 90 degrees either way and pull it straight out. Now the only thing holding the fuse box in is either a 10mm bolt or a plastic push pin. Remove it and place the box aside while you change the battery. Good luck with this.

I am trying to replace the battery on my 2005 Saturn relay. I have removed the cross bar, but the fuse box is in the way. How do I remove this?

You need to detach the fuse box: take out its cover then the 5 bolts securing it. Then tip the battery forward and then pull it out on a diagonal

Have a 01 Tahoe with new red top and fairly new alternator. It charges at about 14v. But if I leave the Tahoe set for a week, it wont start.Where do I look for a voltage leak. The Tahoe seems to be working...

Start with the basics; Is the reason the car does not start is that the battery is discharged after a week of sitting or a case that it won't start without a jump although the battery is still good. If the car just does not start after sitting then try the following; Pull the negative battery cable and let the car sit overnight. Reconnect the cable in the morning and see if it starts. If it does then you are looking for something that is pulling current from the battery. Could be lots of things; light on in the glove box or trunk, a short in a wire, etc. You can try pulling a couple of fuses each evening and in the morning, replace the fuses and see if the car will start after sitting. If it continues to discharge the battery then try another set of fuses. The day it starts after sitting then you have narrowed the electrical system that is discharging your battery. Focus on those systems

Volkswagon radio 2005 golf (2)

Not likely as a result of sitting too long, but there is a possibility that your radio went into theft mode when you cleaned the battery if you disconnected either of the terminals. The fuse for the radio is inside your car, likely in the fuse block on the end of the dash when you open your door. There should be a fuse block schematic either on the door removed to gain access to the fuse block, or in your Owner's Manual.

If it's a radio code issue you may need to consult with your VW Dealer. The radio, however, should power on and then provide you with some indication that the radio has gone into safe mode.
