Does anyone has a instructions on how to install a grill for a civic ex 99?

 

this isn't for a 99, but it should be pretty close: http://www.torontocivics.com/articles/grille/grill.html

you'll probably skip some steps, but it should all be there

hope it helps

 

It isn't rocket science.
1.Unclip the bumper from the top. Open the hood and there are tabs about 6 of them with a flathead screwdriver.

2. Pull the bumper off, 2 phillips (+) crews on each end and I believe 2 or 3 10mm bolts on the underside of the bumper. At this point the bumper should be off.

3. Look at the backside of the bumper where the grill is attached. there should be small screws holding the grill and bumper together unscrew it and replace.

4. Put everything back together.

5. There you're done.
