Chiller & Heat Pump Service Kit for Tesla Model 3 (Up to 2020) | 1133855-00-B
This OEM-grade service kit (Part No. 1133855-00-B) is engineered exclusively for Tesla Model 3 vehicles produced up to 2020, designed to maintain, repair, or restore the performance of your vehicle’s chiller and heat pump systems. These two components are critical to your Model 3’s thermal management—keeping the battery, motor, and cabin at optimal temperatures year-round. The kit includes all essential, Tesla-matched parts to avoid mismatched components and ensure long-lasting reliability.
1. Key Specifications & Compatibility
Feature
Details
Part Number
1133855-00-B
Compatible Vehicle
Tesla Model 3 (production years up to 2020; covers Standard Range, Long Range, and Performance trims with factory heat pump/chiller systems)
Kit Function
Service, maintenance, and repair of Model 3’s chiller (cools battery/motor) and heat pump (heats cabin efficiently)
Works with Tesla-approved R1234yf refrigerant (factory-spec for 2017–2020 Model 3)
Note: Exact components may vary slightly by kit batch, but all meet Tesla’s service standards for chiller/heat pump systems.
2. Why This Service Kit Matters for Your Pre-2020 Model 3
Your Model 3’s chiller and heat pump work in tandem to solve two critical problems:
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).
Over time, the O-rings, gaskets, and filters in these systems degrade:
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).
This kit replaces all these wear parts in one purchase—no need to source individual components (which often don’t match Tesla’s specs) and risk costly rework.
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
Generic service kits use low-quality O-rings that break down in 6–12 months or gaskets that don’t fit—leading to repeat leaks and service visits. This kit:
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
Install this kit if you notice these signs of chiller/heat pump wear:
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:
Recovering remaining refrigerant (per EPA guidelines for R1234yf).
Flushing the system to remove old oil/debris.
Installing kit parts (O-rings, gaskets, filter).
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.
