Installation Instructions
Installation of WeatherTech Mud Flaps is designed to be quick and simple, typically taking only minutes per flap without the need for specialized tools or vehicle modifications. No drilling is required, as the mud flaps utilize existing factory mounting points.
Required Tools:
- T15 Torx Key (for removing existing screws)
- Supplied Hex Key (included with your mud flaps)
Installation Steps:
- Prepare the Vehicle: Ensure the area around the wheel wells where the mud flaps will be installed is clean and free of dirt or debris. It is not necessary to remove the wheels or tires for installation.
- Identify Mounting Points: Locate the existing factory mounting points in the wheel well. The WeatherTech Mud Flaps are custom-designed to align perfectly with these points.
- Remove Existing Fasteners: Using a T15 Torx key, carefully remove any existing screws or fasteners from the factory mounting points. Note that clearance in the rear wheel wells may be limited, requiring careful manipulation of the tool.
- Position the Mud Flap: Align the WeatherTech Mud Flap with the now-empty factory mounting points. Ensure the mud flap sits flush against the vehicle's fender.
- Secure the Mud Flap: Use the supplied hex key and the new hardware provided with your WeatherTech Mud Flaps to secure them firmly into the factory mounting points. Do not overtighten.
- Repeat for Remaining Flaps: Follow the same steps for the remaining mud flaps (front and rear, on both sides of the vehicle).
For detailed visual instructions, please refer to any specific installation guides or videos provided by WeatherTech for your exact vehicle model.

Operating Instructions
Once installed, your WeatherTech Mud Flaps operate passively by deflecting road debris away from your vehicle's painted surfaces and lower body. No active operation is required. They are designed to withstand various weather conditions and road environments, providing continuous protection.
Maintenance
To ensure the longevity and effectiveness of your WeatherTech Mud Flaps, follow these simple maintenance guidelines:
- Regular Cleaning: Clean the mud flaps regularly with soap and water, especially after driving in muddy or dusty conditions, to prevent buildup of dirt and grime.
- Inspection: Periodically inspect the mud flaps and their mounting hardware for any signs of damage, cracks, or looseness. Ensure all fasteners remain secure.
- Avoid Harsh Chemicals: Do not use abrasive cleaners or harsh chemicals, as these may damage the proprietary thermoplastic resin material.
Troubleshooting
While WeatherTech Mud Flaps are designed for a perfect fit and easy installation, here are some common issues and their solutions:
- Mud Flap Does Not Fit Flush:
Solution: Double-check that you have the correct mud flap for the specific wheel well (front/rear, left/right). Ensure all existing factory fasteners have been completely removed and that no debris is obstructing the mounting surface. - Fasteners Are Difficult to Install/Tighten:
Solution: Ensure the mud flap is correctly aligned with the mounting holes. Apply gentle, even pressure while starting the fasteners. If using a T15 Torx key, ensure it is fully seated in the screw head. For tight spaces, a smaller, angled tool may be helpful. - Mud Flap Appears Loose After Installation:
Solution: Re-tighten all mounting fasteners. Avoid overtightening, but ensure they are snug. If the issue persists, inspect the mud flap for any manufacturing defects or damage.
If you encounter persistent issues, please contact WeatherTech customer support for assistance.
