2003-2004 Mazda 6 Wheel Cover Guide: Avoiding Damage and Loss
This guide covers the common issues, replacement costs, and buying advice for the 7-spoke, 16-inch wheel cover used on the 2003-2004 Mazda 6.
- This 7-spoke wheel cover (GK2A-37-170) ONLY fits 2003-2004 Mazda 6 models with 16-inch steel wheels.
- When buying used, the most critical step is to inspect the back and confirm all plastic retaining clips are intact and not cracked.
- The primary causes of failure are impacts from potholes/curbs and age-related brittleness of the plastic clips.
- Installation is a simple DIY task, but ensure the cover is aligned with the valve stem and fully snapped into place to prevent it from falling off.
Symptoms of Wheel Cover Failure
Failure for a wheel cover is typically related to physical damage or it becoming detached from the vehicle. Unlike mechanical parts, there are no error codes, but the symptoms are usually easy to spot or hear.
1. Missing Wheel Cover
The most obvious symptom is a bare, black steel wheel where a silver 7-spoke cover used to be. Wheel covers can be knocked off by hitting potholes, curbs, or other road debris. Improper installation or weakened retaining clips can also cause a cover to fall off during normal driving.
2. Rattling or Clicking Noises
A rattling, clicking, or creaking sound coming from one of the wheels, especially at low speeds, often indicates a loose wheel cover. This happens when one or more of the plastic retaining clips on the back are broken or the metal retention ring has lost tension. The cover is no longer held tightly against the wheel and moves around, causing the noise.
3. Visible Cracks or Damage
Visual inspection may reveal cracks, deep scuffs (curb rash), or broken sections of the plastic. Impacts from curbs are the most common cause of this type of damage. While minor scuffs are cosmetic, significant cracks can compromise the structural integrity of the cover, making it more likely to break apart or fall off.
Warning: A loose or damaged wheel cover can detach from the vehicle at speed, becoming a dangerous projectile and a hazard to other drivers. If you hear a rattling noise from your wheel, it's best to inspect and secure or remove the cover as soon as possible.
Buying a Used 2003-2004 Mazda 6 Wheel Cover
Buying a used OEM wheel cover is often a smart choice, as it ensures a perfect match in design and fit compared to sometimes ill-fitting universal aftermarket options. However, careful inspection is key to getting a good part.
Key Inspection Points for a Used Wheel Cover:
- Check All Retaining Clips: This is the most critical inspection point. Turn the cover over and examine the plastic clips around the perimeter. Ensure all clips are present and free of cracks. Even one broken or weak clip can prevent the cover from seating securely and lead to it falling off.
- Inspect the Retention Ring: Most snap-on covers have a steel wire ring that provides tension to the clips. Make sure this ring is present, not excessively rusted, and properly seated in its channel on the clips.
- Look for Hidden Cracks: Carefully inspect the entire surface, front and back, for cracks. Pay special attention to the areas around the spokes and the outer lip. A crack that seems minor can quickly spread from road vibrations and temperature changes.
- Verify Compatibility: This wheel cover, OEM part number GK2A-37-170, is a 7-spoke design specifically for the 16-inch steel wheels on the 2003-2004 Mazda 6 and Mazda Mazda6. It will not fit models with alloy wheels, the Mazdaspeed6, or other wheel sizes.
Pro Tip: When buying online, look for listings with clear, high-resolution photos of both the front and, most importantly, the back of the wheel cover so you can inspect the clips before purchasing.
Known Issues, Recalls, and TSBs
There are no recalls or Technical Service Bulletins (TSBs) issued by Mazda or the NHTSA specifically for the wheel covers on the 2003-2004 Mazda 6. Issues with this part are related to general wear, road hazards, or installation error rather than a specific manufacturing defect.
However, the 2003-2004 Mazda 6 was subject to several significant recalls related to Takata airbag inflators. While unrelated to the wheel covers, it is crucial for any owner of this vehicle to ensure these safety recalls have been performed.
Cost Comparison
Prices for a single wheel cover can vary significantly based on the source and condition.
| Part Type | Estimated Price (Single Cover) | Notes |
|---|---|---|
| New OEM | $48 - $75 | Purchased from a Mazda dealership or online OEM parts retailer. Guarantees perfect fit and finish. |
| New Aftermarket | $20 - $45 (often sold in sets) | Available from general auto parts stores. Quality and exact color/style match can vary. May be less durable than OEM. |
| Used OEM | $25 - $55 | Available from salvage yards or online sellers. Offers OEM quality at a lower price, but condition must be carefully inspected. |
| Shop Labor | $0 - $25 | Most tire shops will install a wheel cover for free if you are having other tire work done. If done as a standalone job, it would be a minimal charge, if any. |
Installation Guide
Replacing a wheel cover is a simple DIY task that requires minimal tools.
- Difficulty: 1/5 (Beginner)
- Estimated Time: 5 minutes
- Tools Needed: Wheel cover pry tool or a flat-head screwdriver with the tip wrapped in tape (to prevent scratching the wheel).
Removal:
- Find a notch or sturdy opening along the edge of the wheel cover.
- Insert the pry tool or protected screwdriver and gently pry outwards.
- Work your way around the cover, prying in a few different spots to release the clips evenly until the cover pops off.
Installation:
- Align the new wheel cover with the wheel. There is an indentation or cutout in the cover that must be aligned with the tire's valve stem.
- Once aligned, press the cover onto the wheel. Start by pushing it into place with the palms of your hands.
- Give the cover a series of firm taps with the heel of your hand around the perimeter to ensure all the clips snap securely into place. Do not use a hammer, as it will crack the plastic.
- Pull on the edges of the cover to confirm it is seated tightly and does not move.
Pro Tip: For extra security, especially if you live in an area with poor road conditions, you can use two black or silver zip ties to secure the cover to the steel wheel. Loop them through the spokes of the cover and the openings in the steel wheel for a discreet and effective way to prevent loss.
