CFN Brand 265mm Automotive Desiccant for Tesla Model Y | GZP0283

Why This Desiccant Is Non-Negotiable for Model Y’s AC/Heat Pump

Durability & Compatibility Built for Model Y’s Systems

• Core Material: Premium 3A molecular sieve (the same type Tesla uses OEM)—chemically stable, non-toxic, and resistant to breakdown from refrigerant (R1234yf, the type Model Y uses). It won’t leach contaminants into the system or lose absorption capacity prematurely.
• Protective Casing: A breathable, refrigerant-resistant mesh bag (sealed at both ends) holds the molecular sieve in place—preventing particle loss while letting refrigerant and moisture flow through for absorption. The 265mm length is precision-cut to fit the Model Y’s accumulator without folding or jamming (a common issue with ill-fitting desiccants).
• Maintenance Alignment: Matches Tesla’s service intervals—recommended replacement every 4 years for Model Ys with heat pumps, and every 6 years for non-heat pump models. Replacing it on schedule avoids moisture buildup that leads to costly AC repairs (e.g., compressor replacement, which can cost thousands).

Installation: Routine for AC Service (Professional Recommended)

1. Recover Refrigerant: A certified technician will first use an AC recovery machine to safely remove all refrigerant from the Model Y’s system (required by environmental regulations).
2. Access Accumulator: The accumulator (located near the front of the vehicle, connected to the AC compressor) is opened, and the old desiccant is removed.
3. Install New Desiccant: The CFN 265mm desiccant is placed into the accumulator—ensuring it’s centered and the mesh bag isn’t torn.
4. Reassemble & Test: The accumulator is sealed, the system is evacuated (vacuumed) for at least 30 minutes to remove residual moisture, then recharged with fresh R1234yf refrigerant. A leak test is performed to confirm the system is tight.

Key Compatibility Note

• Routine AC/heat pump maintenance (following Tesla’s service schedule).
• Fixing moisture-related AC issues (e.g., weak cooling, ice buildup).
• Replacing the desiccant after AC system repairs (e.g., hose replacement, compressor service).
