To remove the arches from the car
1.
remove the caps that cover the nuts that hold the wiper arms 17mm remove the arms.
2.
Now remove the plastic cover that is held on with two torque screws.. Disconnect the pipes that feed the washer jets..
3.
Undo the torque screw that holds the arch on at the front that you can now see now that's why you have removed the plastic cover..
4.
Now open the door and pull down the rubber seal to reveal EIGHT small torque screws remove these.... Now it's time to remove the arches...
5.
You may need a hand with this part as to prevent any damage to the arches near the bonnet, (put a cloth in between ) start at the front and now pull firmly towards yourself and it will unclip, as you go towards the rear, at the very back pull up as there is a location plastic pin that has a small grommet fixed to the car's shell... Now if you have done this you should be holding one of your arches..
6.
To refit arches, put back on in reverse order...
7.
Don't forget to put your water pipes back on... Also line up wiper arms to the two dotted lines on the windscreen so you know that they will be set correctly
Hope this helps you out and other RCZers too
All drive safe and stay lucky
