Recommended Parts for Tesla Battery Maintenance & Replacement
If you’re working on your Tesla’s battery pack, certain parts may need replacing. While some components can be cleaned and reused, others are best swapped out for new ones. Keep in mind that part compatibility depends on your specific battery model—newer versions may not fit older packs. You can browse Tesla’s Parts Catalog and inquire about availability at a Service Center (SC).
Buying Parts from Tesla: What to Expect
Unlike traditional dealerships, Tesla does not have a walk-in parts department where you can easily order anything. Some components, particularly high-voltage (HV) battery parts, are restricted from customer purchases.
You can attempt to order through the Tesla app by submitting a service request, waiting for confirmation, and picking up the parts once approved. However, some owners find that visiting a Service Center in person yields better results.
Things to Keep in Mind:
✅ Tesla’s “Over-the-Counter” (OTC) parts list is inconsistent—some SCs may sell a part while others won’t.
✅ Policies change frequently, meaning a part that was available last year may now be restricted.
✅ If Tesla refuses to sell a component, third-party sellers or online marketplaces might be your only option.

Other Useful Supplies (Non-Tesla Sources)
1. Coolant & Fluids
🔹 G48 Coolant – Tesla’s thermal system uses a 50/50 premix, but concentrated versions can be found for better value.
2. Installation Aids
🔹 M5 × 0.75 bolts (x4) – Useful as alignment pins for the battery lid
🔹 M8 × 1.25 bolts (x4) – Helps align the pack when reinstalling
3. Sealants & Adhesives
🔹 Sikaflex-221 (x3 tubes) – Used for securing the battery lid; offers a longer working time for DIY repairs – Where to buy
🔹 Permatex The Right Stuff – Gasket sealant for the fuse cover and coolant rapidmate. Where to buy.
4. Sealing Tape & Caps
🔹 Butyl Tape (1/8″ thick, 30′ long, ~3/4″ wide) – Commonly used for sealing and waterproofing. Where to buy.
🔹 5/16″ Rubber Caps – Prevents coolant drips when moving modules. Where to buy.
Final Thoughts
- Plan Ahead 🔹 Many SCs will refuse to sell HV-related parts, so have alternatives ready.
- Double-Check Compatibility 🔹 V1 and V2 pack components are not always interchangeable.
- Persistence Pays Off 🔹 What one SC refuses, another might sell—try different locations.
- eBay & Salvage Networks 🔹 If Tesla won’t sell a part, third-party sources are often your best bet.
Whether you’re repairing a pack, upgrading components, or refreshing worn parts, getting the right supplies in advance will save time and prevent unexpected delays.
