It's in the service manual, but I don't remember the page numbers. Straighforward but a pain.
I did this to install mesh last summer.
1. remove and disconnect both front turn signals
2. lift front end
3. remove both front tires (you don't have to but it makes it much easier)
4. remove both front wheel well liners (again, you don't have to but it makes it much easier. If you don't, you'll at least have to loosen them both in the front so you can fold them back about halfway)
5. There are two or three 10 or 13mm nuts to remove from inside each fender well
6. remove the external temp sensor from it's front bumper mount just in front of the radiator
7. unplug the horn
8. remove and plug the windshield washer pump tube
9. now you can actually remove the last bolts holding it on, there are three on either side, about 14-15mm I think.
10. once it's loose, lift gently but firmly upwards and it should come off with some wiggling. Be ready because it weighs about 40 lbs and have something like an old cover or something soft on the ground to put it on. Once off, it's "unstable" and doesn't want to sit upright on it's own and will want to tip over, which will scratch it. (ask me how I know!)
Reverse these procedures to put it back on, and remember now is a good time to clean out all the leaves and crap that accumulate in front of the radiator, check your AC tubes, straighten and fix any of the plastic underbody pieces, etc.
Good luck and I hope this helps! Find and print the pages in the service manual, they help a lot.
