Front Right-Hand (RH) Wheel Liner Assembly for 2023+ Tesla Model 3 | 1694557-00-E (CFN Brand)

Core Functions

1. Key Component Shielding
   Acts as a robust barrier between the front right wheel well and critical underbody parts, such as the front suspension control arms, brake hoses, ADAS (Advanced Driver-Assistance Systems) sensor wiring (e.g., for forward-facing cameras or ultrasonic sensors), and cooling system pipelines. It blocks road debris (gravel, sharp stones, broken glass) kicked up by the right front wheel during driving—preventing scratches, impacts, or premature wear to sensitive components like suspension bolts or sensor wiring.
2. Corrosion & Debris Prevention
   Seals the front right wheel well to stop mud, rainwater, and road salt from splashing into the underbody cavity. This avoids corrosion of metal components (e.g., brake caliper brackets, subframe joints) and reduces the risk of water-induced short circuits in nearby electrical wiring. For the 2023+ Model 3’s updated front-end electrical layout, the liner’s tight fit also prevents debris accumulation that could interfere with ADAS sensor performance.
3. Aerodynamic & Noise Optimization
   Follows Tesla’s 2023 Model 3 facelift aerodynamic design to guide airflow smoothly around the right front wheel. It minimizes wind resistance (supporting the vehicle’s energy efficiency, especially during highway cruising) and reduces road noise caused by airflow turbulence in the wheel well—preserving the facelifted Model 3’s enhanced cabin quietness.

Durable Construction

• Main Liner Body: Made of high-grade PP (Polypropylene) plastic with an integrated reinforced rib structure. The PP material has a notched impact strength of ≥5.5kJ/m², resisting cracking from small stone impacts or minor curb contact; the reinforced ribs enhance structural rigidity, preventing deformation even under long-term pressure from wheel vibration or uneven roads.
• Mounting Hardware: Includes OEM-spec high-tensile nylon snap clips (resisting breakage during installation/removal) and galvanized steel mounting brackets (tensile strength ≥300MPa). The galvanized coating on brackets prevents rust from underbody moisture or road salt, ensuring the assembly stays securely attached.
• Environmental Adaptability: Withstands extreme temperature fluctuations (-30°C to 85°C)—remaining flexible in cold winters (no brittle cracking) and stable in hot summers (no softening or warping). It also resists UV fading (passes 400-hour ASTM G154 UV tests) and chemical corrosion from car wash detergents or road de-icing salt.

Installation 要点

1. Vehicle Preparation: Lift the front right side of the vehicle with jack stands (ensure stable support); remove the front right wheel to access the wheel well. Gently peel back the front fender’s lower trim (if overlapping) to expose the wheel well’s mounting points.
2. Old Liner Removal: Use a trim tool to detach the plastic snap clips and 8mm bolts securing the old liner (typically 9–11 fasteners: 6 clips + 5 bolts). Note each fastener’s position to avoid misplacement, then pull the old liner away—take care not to damage adjacent parts like the fender trim or brake lines.
3. Cleaning: Wipe the wheel well’s mounting surface with a dry cloth to remove dust, mud, or residual adhesive—ensuring the new assembly fits tightly.
4. New Assembly Installation: Align 1694557-00-E with the wheel well’s mounting points (ensure edges fit snugly against the front bumper and fender). Snap the clips into place (listen for a “click” to confirm security), then hand-tighten the 8mm bolts to avoid cross-threading.
5. Torque Fastening: Use a torque wrench to tighten bolts to 4±0.3 Nm (per Tesla’s 2023+ Model 3 specs)—over-tightening may crack the liner’s plastic tabs.
6. Post-Installation Check: Reinstall the front right wheel, lower the vehicle, and inspect the wheel well. Confirm the liner is flush with the fender/bumper, with no gaps for debris entry.

Note: This part is right-hand (RH) specific—do not interchange with left-hand (LH) liners (e.g., 1694553-00-E). Pre-2023 Model 3 wheel liners are incompatible, as they do not match the 2023+ wheel well contour.
