1118811-00-A Electronic Fan Support Rubber Pier Bracket (CFN Brand) For Tesla Model 3/Y (2017-)

1. Basic Information

2. Core Selling Points

• CFN-Exclusive Material & Durability: Made of high-elastic NBR with a Shore hardness of 55±5 HA and a rebound rate of ≥85%, which can effectively absorb high-frequency vibrations (10-500Hz) from the fan. Compared with ordinary rubber brackets, it reduces abnormal noise by 40%. The embedded galvanized steel sleeve passes a 500-hour salt spray test (per ASTM B117) without rust, adapting to humid, rainy, or snowy road environments and extending the service life to ≥5 years.
• Precise Fit for Tesla OEM Standards: The overall size (outer diameter: 38mm, inner diameter: 12mm, height: 25mm) is calibrated to Tesla’s original design, with a dimensional tolerance of ±0.3mm. It directly matches the mounting holes of Model 3/Y’s electronic fan and body brackets, requiring no modification during installation—ensuring a tight fit and avoiding loose connections.
• Vibration Isolation & Noise Reduction: The rubber structure is designed with a multi-layer damping groove, which can disperse and absorb vibration energy from the fan (up to 80% vibration isolation efficiency). It prevents vibration from being transmitted to the vehicle frame, avoiding "hum" or "rattle" noises in the cabin during fan operation (especially at high fan speeds).
• Load-Bearing & Impact Resistance: The embedded galvanized steel sleeve enhances the bracket’s axial load-bearing capacity to 150N, supporting the weight of the electronic fan (≈1.2kg) stably without deformation. The rubber material also resists impact from road debris, preventing cracks or breakage in daily use.

4. Installation Tips

1. Pre-Installation Preparation: Ensure the vehicle is turned off and the 12V battery is disconnected (to avoid electrical risks when removing the fan). Clean the mounting area of the fan and body bracket to remove dust, oil, or debris.
2. Bracket Alignment: Confirm the direction of the rubber pier bracket—align the embedded steel sleeve’s inner hole with the fan’s mounting bolt hole and the body bracket’s hole. The larger end of the rubber bracket should face the fan side for stable support.
3. Secure Installation: Pass the M6 mounting bolt (matching Tesla’s original specification) through the fan hole, the rubber bracket’s inner sleeve, and the body bracket hole. Tighten the bolt to a torque of 8±1 Nm (per Tesla’s factory standard) to avoid over-tightening (which may damage the rubber) or under-tightening (which causes looseness).
4. Post-Installation Check: Reconnect the 12V battery, start the vehicle, and activate the cooling fan (e.g., via "Max Cool" climate control). Listen for abnormal noises and check if the fan operates stably without obvious vibration.

5. After-Sales Support (CFN Brand)

• Warranty: 2-year/40,000km warranty (whichever comes first), covering defects such as rubber cracking, steel sleeve rust, or deformation (excluding damage caused by improper installation, collision, or overloading).
• Quality Guarantee: If the bracket is incompatible with your Tesla Model 3/Y (2017-) or has manufacturing defects within 30 days of receipt, free replacement or full refund is provided (with the product unused and in original packaging).
• Technical Assistance: CFN’s EV parts specialists are available via email/chat to provide installation guidance (e.g., torque verification, alignment tips) and troubleshoot issues related to use.

6. Bulk Purchase & Usage Tips

• Bulk Pricing: For repair shops, fleet operators, or distributors, bulk orders (≥50 pieces) enjoy preferential pricing, with customized packaging (20 pieces/box) and flexible delivery schedules available.
• Maintenance Suggestion: Inspect the bracket every 20,000km—check for rubber hardening (Shore hardness >70 HA), cracks, or steel sleeve rust. Replace in time if any of these issues occur to avoid affecting fan stability.
• Matching Recommendation: For balanced vibration isolation, replace the left and right electronic fan rubber pier brackets at the same time (even if only one shows signs of wear), ensuring consistent performance of the cooling system.
