i/c = intercooler
its a bit of a pain to get to but here goes:
1. jack up passenger side of car for easier access
2. undo all the clips for the guard liner, they go all the way to the front of the bar including some bolts too
3. pull the liner out
4. take your airbox out
5. undo the hose clamps that are near the intercooler
6. undo all the brackets that hold the i/c in place, undo from both the body and intercooler (there is one on the very inside of the guard too)
7. hit all the rubber hoses up with some wd40 and take a break
8. remove the bolts from one of the pipes from under where the airbox sits (two bolts on either side of the return pipe)
9. now remove the i/c, just needs wiggling to break the seal on the rubber
10. clean it with degreaser - rinse thoroughly
11. blow it out with air
12. leave it sitting in the sun with the cores running vertically so the water runs out into one of the end tanks
13. blow it out again
14. re-install
15. ?????????????????????????
16. Profit
