Grille removal for first-timers: 15-20 min (5-8min if done b4)
Not hard at all. its all basically prying off several plastic bolts with leverage.
Tools:
2 medium-sized flathead screwdriver
1 small-sized flathead screwdriver (the screwdriver that comes with eyeglass repair kits worked great)
1) pop da hood
2) TAKE NOTE
-there are 2 areas where bolts need to be removed (see pic below):

*about 7 are on
top of the grille (mayb 8; i forgot)
*6 are
inside the grille
-to get to the inside bolts, one must first remove top bolts!
3) START WITH BOLTS ON TOP
-with both medium flatheads, take out the bolts by prying them out with leverage (kinda like prying a door open). Using 2 screwdrivers facilitated this
(see below...i copy/pasted in one more of my hands to show)
-Once top bolts are removed, 1ST PHASE COMPLETE.
-grille will start to feel like it'll come off/flexible bc you took off mad bolts. use this to your advantage to get to inside bolts. DONT BE AFRAID TO
GENTLY BEND GRILLE.
4) NOW TAKE OFF INSIDE BOLTS/LATCHES
-start with the CORNER BOLTS/LATCHES of the right or left (doesnt matter)
-for less confusion, start with the right.
-take one medium flathead screwdriver and pry this bolt/latch out. Leverage helps (these corner ones are the hardest)
-once its off, the rest are easier to come out.
below are pics of corner bolt/latch removal:

(can't see bolt/latch here bc of angle)
5) take off middle bolt/latch with small flathead by placing it under the bolt/latch. once screwdriver is under, apply pressure towards you/towardsthe sky (dont know how else to describe it?) and it should come off. kinda like pressing a small button; much easier than that corner bolt/latch
6) NOW take off bottom bolt/latch. Use same method as step 5
7) Repeat 4-6 with left side of grille
8) Once Steps 4-7 are complete, GRILLE WILL COME OFF!
