2016 Scion iA Grille: Decoding Upper, Lower, and Trim Part Numbers

Understanding the 2016 Scion iA's Multi-Piece Grille

When replacing the grille on a 2016 Scion iA, it's crucial to know that it is not a single component. The front end uses a multi-piece assembly, and you must identify exactly which part you need before purchasing a replacement. This is a common point of confusion for owners.

• Upper Grille: This is the main, large black textured section at the top of the bumper opening where the Scion emblem is mounted.
• Lower Grille: This is the black textured insert at the very bottom of the bumper opening. It often takes the most abuse from road debris.
• Grille Trim / Molding: This is the painted or chrome accent piece that often surrounds or divides the grille sections. On the iA, this is typically a prominent center bar.
• Grille Protectors: These are smaller, often overlooked plastic pieces that may sit at the sides of the lower grille opening, sometimes near the fog lights (if equipped).

Symptoms of a Bad or Failing Grille

Grille failure is almost always due to physical damage rather than a manufacturing defect. The symptoms are purely visual.

Cracks, Holes, or Dents

The most common symptom is visible damage from impacts. Small rocks can cause chips and cracks, while minor collisions with curbs, parking blocks, or other vehicles can cause significant breakage. Large holes can leave the radiator and A/C condenser vulnerable to damage.

Broken Mounting Tabs

On the back of every grille piece are numerous plastic tabs and clips that secure it to the bumper cover. These can become brittle with age and snap during even a minor impact or during removal. A grille with broken tabs will not sit flush, may look misaligned, and can vibrate or rattle while driving.

Faded or Peeling Finish

Constant exposure to UV rays from the sun and harsh weather can cause the grille's finish to fade from a deep black to a dull gray. If the grille has a painted or chrome finish, it can begin to peel or flake over time, detracting from the vehicle's appearance.

Buying a Used Grille for Your Scion iA: A Checklist

A used OEM grille is often a better choice than a cheap aftermarket alternative because it guarantees a perfect fit and original material quality. Here’s what to inspect before you buy.

1. Confirm the Exact Piece: First, determine if you need the upper grille, lower grille, or a trim piece. Take a photo of your car's front end to compare with the seller's part.
2. Inspect All Mounting Points: This is the most critical check. Carefully flip the grille over and inspect every single mounting tab and clip location. Even one or two broken tabs can result in a poor fit. Pass on any grille with multiple broken tabs, especially at the corners.
3. Check for Cracks: Examine the entire surface, especially around the screw holes and corners, for hairline cracks. A small crack can grow over time due to engine vibration and temperature changes.
4. Verify the Finish: Check for deep fading, chemical stains, or peeling on chrome/painted sections. Ensure the texture of a used part will closely match any remaining original pieces on your vehicle.

2016 Scion iA Grille Replacement

Replacing any of the grille components on the Scion iA requires removing the entire front bumper cover. While not technically complex, it is an involved process that requires patience to avoid scratching the paint.

• Installation Difficulty: 3 out of 5
• Estimated Time: 1.5 - 2.5 hours
• Tools Needed: Socket set (10mm), Phillips screwdriver, flathead screwdriver or trim removal tool, protective blanket.

Basic Replacement Steps

1. Open the hood and remove the plastic clips and/or bolts securing the top of the bumper cover to the radiator support.
2. In each front wheel well, remove the screws and clips holding the bumper cover edge to the fender liner and fender.
3. Underneath the front of the car, remove all clips and bolts securing the bottom of the bumper cover to the splash shield.
4. Starting at a corner where the bumper meets the fender, gently but firmly pull the side of the bumper cover outwards to release it from the retaining clips under the headlight. Repeat on the other side.
5. With both sides free, pull the entire bumper cover forward. If you have fog lights, disconnect the wiring harnesses before setting the bumper cover aside on a soft blanket to prevent scratches.
6. With the bumper cover removed, you can access the Phillips screws and plastic tabs on the back that hold the grille pieces in place. Carefully remove the damaged piece and install the new one.
7. Re-installation is the reverse of removal.
