Re: Removal of Front Bumper on a AR 156
The headlight washers are held on with an almight great big nut underneath the bumper. When I tried to undo mine to transfer to a new bumper the plastic sheared so be gentle with it if you are removing.
The bumper has 4 T20 torx bolts under the centre grille sections (which are held in place by 2 philips screws on either side of the upper grilles and 2 in the central grille section), then there are another 3 T20 torx bolts unber the front bumper lip and and additional 2 each side of the top of the bumper which screw in to the underside of either wing.
Many people advise removing the wheels and arch liners to get at these but I found that putting the wheels on opposite lock and prying the edge of the arch liner away gives enough access with the right tool.
The washer hose feeds from the left hand side of the front of the car and the fog light wiring is clipped in to the right hand side, you may have to free these or disconnect to allow you to remove the bumper fully to work on.
As the Haynes saying goes,"refitting is the opposite of removal".
I couldn't find a replacement bumper in my colour with the washer cutouts, so I disconnected my headlight washers and fitted a bumper without them, but the front end does seem lacking without them. Having a bumper with the hole, but no washer just looks wrong, so if you have the time and patience to refit the missing one, its worthwhile.
Best of luck
