There are some reasons why you should want remove the front grill of your chrysler 300. This is one of the most commonly customized cars, and aftermarket grilles are often used to replace the stock car.
Other reasons for removing the grille could include replacement or repair after an accident, or to gain more access to the engine for mechanical work.
Steps to remove the front grille of the Chrysler 300

Removing the grate or grill can be a tedious process that takes several hours to complete, as some of the screws are very difficult to reach. An offset screwdriver will be needed for this process.
These ratcheting screwdrivers operate at a 90-degree angle and are available at most automotive parts stores. Without one of these tools, it would be nearly impossible to access all of the bolts that hold the grill in place without removing the entire front bumper.
1.Open the cover
First you need to open the hood of your Chrysler 300 and look straight down into the grille area. You will see two plastic covers on each side of the grill that overlap the top of the grill. These will be in the way of the mounting screws, and must be removed. Grab them and pull them out, using firm pressure. They will simply drop out of the vehicle, set them aside for now.
2. Remove the inserts
Remove the four plastic inserts that the covers you just removed had hidden. These inserts resemble thumbtacks, and can be popped out of place without unscrewing.
You may need to pry them out with the tip of a flathead screwdriver. They are small and can easily get lost, so keep them in a safe place for when you put everything back together.
Gently pull forward (away from the car) the outer cover that is attached to the bumper. Now that the plastic inserts have been removed, you will be able to walk freely away from the car, but it will not come off as it is still attached at the bottom. A little extra space is all that is needed for this job, so there is no need to further disassemble the front end.
3.Take out the top screws
Look inside the perimeter of the grill from inside the engine compartment. There are 10 total screws that hold the grille in place. There is one plastic square head screw on each side and eight Phillips head screws, half at the top and half at the bottom.
To get started, remove the top four screws with a Phillips-head screwdriver. These should come off easily. Also remove the two square-head plastic screws located on either side of the grill, using a Phillips-head screwdriver.
4.Remove the remaining four screws
Feel the bottom of the grille from the inside and note the location of the four remaining Phillips head screws. These are in a very small space, and it is impossible to remove them with a normal screwdriver.
Insert a Phillips bit into the offset screwdriver and slide it under the grille. You will now be able to loosen each of the screws and move them out of the way as well. Be careful when removing the last one, since the grille is free and can fall from the car.
