How to...Change the Battery

I finally did the deed on Christmas Day. I had to work off all that rich food somehow.
It's a bit fiddly but otherwise it's not that bad. You don't even need a power supply to retain the radio memory, the only thing you'll lose is the date and time.

From memory, for a 2.0 HDI 160:

The air cleaner housing<ul>[*]Undo the four screws on the air cleaner housing. You don't need to remove them as they're captive.[*]Slacken the jubilee clip on the top intake pipe.[*]Unplug the sensor on the intake pipe. The plug is a bit of a pain.<ul>[*]Slide the coloured retaining clip until it stops. Don't pull it out.[*]At the other end to the retaining clip is a black plastic tab. Pull it away from the body and the plug should come out. Don't force it.[/list][*]Unclip the sensor cable from the intake pipe.[*]Remove the top of the air cleaner housing.[*]Remove the air filter.
[/list]The junction box
<ul>[*]The junction box sits on top of the battery box. Unclip and remove the cover.[*]Remove the cable from the battery terminal.
[*]Follow the cable from the battery terminal to the 10mm nut. Remove the nut and free the cable. There is another nut at the top, leave it alone.
[*]Unclip the cable clamp on the front of the battery box.[*]Unplug the big and obvious plug below the junction box.<ul>[*]Slide the coloured retaining clip until it stops. Don't pull it out.[*]At
the other end to the retaining clip is a black plastic tab. Pull it
away from the body and the plug should come out. Don't force it.[/list][*]Release the clips on the right of the juntion box.[*]Slide the junction box to the right to free the retaining tab, then slide it up until it comes away from the battery box. You may have to wiggle it around a bit.[*]Remove the fuxebox lid. It will stop the junction box from sliding off and annoying you.[*]Slide / shuffle the junction box to the right onto the top of the fusebox.[/list]The battery
<ul>[*]Remove the battery box lid. This is a bit of a pain.
<ul>[*]Look at the round lump at the bottom on the left side of the battery box. You should be able to see the direction to pull the lid to remove it.[*]Lift the lid from the bottom and pull it forward. Once the first clip lets go it will be easy.[*]Pull the lid forward and remove it.[/list][*]Undo the 10mm bolt on the battery clamp and remove the clamp.[*]Slacken the 10mm screw on the battery terminal clamp and remove the cable. Wiggle as required.
[*]Remove the battery without crushing your toes.[/list]The new battery
<ul>[*]There is a retaining flange on both sides of the battery at the bottom, this is what the battery clamp holds it by. Some batteries come with additional plastic spacers attached to the flanges. If yours has the spacers, remove both of them.[*]Remove the terminal covers if your battery has them.
[*]If you want to clean any oxide or corrosion from the battery terminals, do it now.[*]Lift the battery into the battery box. The terminals go on the left.[*]Slide the battery to the right so the flange on the battery goes under the edge of the battery box.[*]Secure the battery with the retaining clamp. The bolt is still 10mm.[/list]Put it back together
<ul>[*]Reassembly is pretty straight forward. Read the instructions backwards.
[*]Don't forget the negative (rear) battery cable!
[*]Be careful not the trap any other cables.[*]Feel free to put petrolium jelly on the terminals if you want to.[*]When you reconnect the positive terminal, the indicators will flash and the car will make strange noises. This seems to be normal.[*]Set the clock.[*]You might want to go for a drive to make sure the new battery is fully charged.
