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

1. Key Specifications & Compatibility

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

• Chiller: Cools the battery pack and electric motor during fast charging, highway driving, or hot weather. It prevents overheating that would otherwise reduce battery range, damage cells, or trigger power limits on the motor.
• Heat Pump: Heats the cabin in cold weather using 30–50% less battery power than traditional resistive heating—critical for preserving winter range (a common pain point for EV owners).

• Cracked O-rings or worn gaskets cause refrigerant leaks, robbing the chiller/heat pump of efficiency (your battery may overheat during charging, or the cabin won’t warm up in winter).
• A clogged filter drier lets debris and moisture circulate, damaging sensitive valves or the heat pump compressor (a single compressor replacement costs $1,000+).
• A failing electric water pump disrupts coolant flow, leading to uneven temperature regulation and "Thermal System Fault" alerts on your touchscreen.

3. Core Benefits of This OEM-Spec Kit

1. Restores Factory-Grade Thermal Performance

• Stops Refrigerant Leaks: Pre-lubricated EPDM O-rings and silicone gaskets create an airtight seal, eliminating leaks that make your chiller/heat pump underperform. After service, your battery stays within the ideal 20–30℃ range during fast charging, and the cabin heats up 2–3x faster in cold weather.
• Protects High-Cost Components: The filter drier traps moisture and metal debris before they reach the chiller’s valves or heat pump compressor, preventing premature (and expensive) failures.
• Matches Tesla’s Efficiency: Every part is calibrated to the exact pressure and flow specs of your Model 3’s thermal system. No more "Battery Temp High" or "Cabin Heating Slow" issues post-repair.

2. Avoids Aftermarket Risks

• Perfect Fit: All parts (from O-rings to hardware) match Tesla’s factory dimensions, so they install seamlessly without modification.
• Refrigerant Resistance: EPDM O-rings withstand the harshness of R1234yf refrigerant (cheap rubber O-rings break down in 6–12 months).
• Durable Water Pump: The included electric water pump uses the same copper windings and reinforced housing as Tesla’s original, ensuring it lasts 80,000+ miles.

3. Saves Time & Money

• One Kit = Complete Solution: No more waiting for separate O-rings, gaskets, or water pumps to ship—everything you need for a full service is included.
• Reduces Downtime: Professional technicians can complete repairs in 2–3 hours (vs. 4+ hours with generic kits that require adjustments).
• Prevents Costly Rework: Mismatched aftermarket parts often fail quickly—this kit’s OEM specs ensure the job is done right the first time.

4. When to Use This Service Kit

• Refrigerant Leaks: Clear oil residue (refrigerant byproduct) under the front of your vehicle, or a "Low Refrigerant" alert on the touchscreen.
• Poor Thermal Performance:
  • Battery overheats during Supercharging (charging speed slows to <50kW).
  • Cabin takes 10+ minutes to reach 22℃ in cold weather (32℉/0℃ outside).
  • Motor power is limited in hot weather (your Model 3 feels sluggish during acceleration).
• Unusual Noises: Hissing from the front (leaking refrigerant) or grinding from the heat pump (debris in the system).
• Routine Maintenance: Recommended every 3–4 years (or 60,000 miles) per Tesla’s service guidelines to prevent premature system failure.

5. Installation & After-Sales Tips

• Professional Installation Required: Servicing chiller/heat pump systems demands specialized tools and expertise. The process includes:
  1. Safely recovering remaining R1234yf refrigerant (per EPA regulations).
  2. Flushing the system to remove old oil, debris, and moisture.
  3. Installing all kit components (O-rings, gaskets, filter drier, water pump).
  4. Recharging refrigerant to Tesla’s exact pressure specs (typically 45–55 psi for the heat pump circuit).
     We strongly recommend a Tesla-certified technician or EV shop with thermal system experience.
• Post-Install Testing: After service, verify:
  • No leaks (via a 30-minute pressure test).
  • Chiller cools the battery to 20–30℃ during 150kW+ Supercharging.
  • Heat pump heats the cabin to 22℃ in <5 minutes (32℉/0℃ outside).
• Warranty Coverage: Backed by a 1-year limited warranty. If any kit part fails due to manufacturing defects (e.g., O-ring cracking, water pump failure), we offer free replacement.
