Chiller & Heat Pump Service Kit for Tesla Model 3 (Up to 2020) | 1133855-00-B

1. Key Specifications & Compatibility

2. Why This Service Kit Matters for Your Pre-2020 Model 3

• Chiller: Cools the battery pack and electric motor during fast charging, highway driving, or hot weather (prevents overheating that reduces range or damages cells).
• Heat Pump: Heats the cabin efficiently in cold weather (uses 30–50% less battery power than resistive heating, preserving winter range).

• Cracked O-rings cause refrigerant leaks (chiller/heat pump lose efficiency; battery overheats or cabin won’t warm up).
• Clogged filters let debris circulate (damages valves or reduces cooling/heating speed).
• Worn gaskets create air gaps (wastes energy and triggers "Thermal System Fault" alerts).

3. Core Benefits of Using This OEM-Spec Kit

1. Restores Thermal System Performance

• Stops Refrigerant Leaks: Pre-lubricated EPDM O-rings and silicone gaskets create a tight seal, eliminating leaks that make your chiller/heat pump underperform. After service, your battery stays cooler during charging, and the cabin heats up faster in winter.
• Protects Critical Components: The included filter drier traps moisture and metal debris before they reach the chiller’s valves or heat pump’s compressor—preventing expensive component failures (a new heat pump compressor costs $1,000+ to replace).
• Matches Factory Efficiency: All parts are calibrated to Tesla’s thermal system pressure specs. No more "cabin not heating" or "battery temp high" warnings after service.

2. Avoids Aftermarket Risks

• Uses Tesla-matched dimensions (O-ring thickness, gasket shape) for a perfect seal.
• Resists refrigerant corrosion (R1234yf is harsh on cheap rubber—EPDM O-rings handle it long-term).
• Includes torque-spec hardware (prevents over-tightening that cracks chiller ports).

3. Saves Time & Money

• One Kit = All Parts: No more waiting for separate O-rings or filters to ship—everything you need for chiller/heat pump service is included.
• Reduces Downtime: Avoids "do-over" repairs from missing or mismatched parts. Professional technicians can complete service in 2–3 hours (vs. 4+ hours with generic kits).

4. When to Use This Service Kit

• Refrigerant Leaks: Puddles of clear oil (refrigerant residue) under the front of the vehicle, or a "Low Refrigerant" alert on the touchscreen.
• Poor Thermal Performance:
  • Battery overheats during fast charging (slows charging speed).
  • Cabin takes 10+ minutes to warm up in cold weather (heat pump isn’t working).
  • Motor limits power in hot weather (chiller can’t cool it).
• Unusual Noises: Hissing from the front of the vehicle (leaking refrigerant) or grinding from the heat pump compressor (debris in the system).
• Routine Maintenance: Recommended every 3–4 years (or 60,000 miles) to prevent premature system failure—per Tesla’s service guidelines for pre-2020 Model 3.

5. Installation & After-Sales Tips

• Professional Installation Required: Servicing chiller/heat pump systems requires:
  1. Recovering remaining refrigerant (per EPA guidelines for R1234yf).
  2. Flushing the system to remove old oil/debris.
  3. Installing kit parts (O-rings, gaskets, filter).
  4. Recharging refrigerant to Tesla’s exact pressure specs.
     We recommend a Tesla-certified technician or shop with EV thermal system experience.
• Post-Install Testing: After service, verify:
  • No leaks (via pressure test).
  • Chiller cools battery to 20–30℃ during charging.
  • Heat pump heats cabin to 22℃ in <5 minutes (32℉ outside).
• Warranty Coverage: Backed by a 1-year limited warranty. If kit parts fail due to manufacturing defects (e.g., O-ring cracking, filter clogging prematurely), we offer free replacement.
