Component / System

Description

Air Conditioning

Depending on its intended sales region, the air conditioning system is filled with R134a or R1234yf refrigerant.

  • 1012403-00-B, REFRIGERANT, R134a
  • 2006643-00-A, REFRIGERANT, R1234yf

For China only, please use the following refrigerant:

  • 1065472-10-A, REFRIGERANT, R134A 13.5KG CYLINDER

If oil needs to be added to the air conditioning system, use the appropriate oil as specified below.

Warning IconA warning icon, calling your attention to a possibly risky situation
CAUTION
Select the corresponding refrigerant oil type according to different types of compressors. Do not mix different types of A/C system oil.
  • Sanden compressor type: use RB100EV A/C oil (part number 1994534-00-A or 1031093-01-A)
  • Denso compressor type: use ND-11 A/C oil (part number 1031093-00-A or 1108849-00-A).
Informational PurposesAn informational icon, calling your attention
Note
For calculations, both ND-11 and RB100EV compressor oils have a density of 0.98 grams/ml at 15°C.
  • Given a value in grams, divide by 0.98 to find the value in ml (milliliters or cc).
  • Given a value in ml (milliliters or cc), multiply by 0.98 to find the value in grams.
If ultraviolet dye needs to be added to the system to troubleshoot a leak, the following leak detector injection kit and refill leak detector dye are Tesla-approved for all Tesla refrigerant systems.

Brake Fluid

DOT 4 BASF Hydraulan 404 (part number 1012041-10-C) is the approved brake fluid.

Informational PurposesAn informational icon, calling your attention
Note
The brake fluid filler cap is marked 'DOT 3'. This is the minimum requirement and does not state to only use DOT 3 brake fluid.
Warning IconA warning icon, calling your attention to a possibly risky situation
CAUTION
Only use new fluid from sealed containers.

Coolant

The cooling system contains an ethylene glycol (phosphate and nitrate free) based coolant.

  • 1029320-00-A, ETHYLENE GLYCOL COOLANT - 50/50 MIX - 1 Gallon
  • 1061466-00-A, ETHYLENE GLYCOL COOLANT - 50/50 MIX - 55 Gallon Drum
  • NA only: 1734463-00-A, COOLANT,ETHYLENE GLYCOL,HEAT TRANSFER FLUID - LOW SILICATE (HTF-LS), 50/50 MIX,OAT

For China only, please use the following coolant:

  • 1012820-10-A, COOLANT, ETHYLENE GLYCOL, 50/50 MIX, 4L
For EMEA only, please use the following coolant:
  • 1119779-00-A, G48 Coolant – 50/50 MIX 1 Liter
Informational PurposesAn informational icon, calling your attention
Note
NA only: Model Y vehicles manufactured in Gigafactory Texas starting on October 2024 were filled with HTF-LS coolant that is orange in color.
Warning IconA warning icon, calling your attention to a possibly risky situation
CAUTION
NA only: Do not mix G-48 and HTF-LS coolant. If the vehicle already has G-48 coolant (blue), top off with G-48 coolant. If the vehicle already has HTF-LS coolant (orange), top off with HTF-LS coolant. If the two fluids are mixed, thermal performance will not be affected, but the fluid color will change to brown, which could interfere with proper cooling system diagnosis in service.

The overall concentration of ethylene glycol should not fall below 50% by volume to make sure that the anti-corrosion properties of the coolant are maintained.

Concentrations of ethylene glycol greater than 60% are not recommended as cooling efficiency will be impaired.

Tesla HTF-LS (NA only) and G-48 coolant is a pre-mixed 50/50 solution of ethylene glycol and water. The coolant is ready to use. Do not add water.

Warning IconA warning icon, calling your attention to a possibly risky situation
CAUTION
Tesla cannot provide warranties for any type of coolant other than HTF-LS (NA only) or Tesla G-48 coolant. Use of other coolants is at your own risk.

Electrical Joint Compound

Penetrox A-13 electrical joint compound (part number 1089974-00-A).

Gearbox Fluid

 To reduce gearbox fluid variances and improve drive unit efficiency, service centers are to transition to KAF1 gearbox fluid for all vehicle drive units. When refilling or topping up drive unit gearboxes, first deplete supplies of the specified SK 212-B, ATF-9, and EDF2 gearbox fluids, and only then substitute with KAF1. KAF1 gearbox fluid is fully backwards compatible with the SK 212-B, ATF-9, and EDF2 gearbox fluids, and incidental mixing of the specified fluid with KAF1 is permitted. Eventually, service centers will only stock KAF1 fluid.
Warning IconA warning icon, calling your attention to a possibly risky situation
CAUTION
SK 212-B gearbox fluid is reddish, ATF-9 and EDF2 fluids are dark purple, and KAF1 fluid is amber colored. If you are unable to determine what fluid is in the drive unit, refill or top up with only KAF1. Do not mix SK 212, ATF-9, or EDF2 gearbox fluids with each other.
  • For all 3DU drive units up to and including Model Year 2023 use ATF-9 (part number 1135241-00-A) or EDF2 (part number 1616951-00-A) or ultimately, KAF1 (part number 1646886-02-A or 1646886-04-A)
  • For all 3DU drive units Model Year 2024 and later use KAF1 (part number 1646886-02-A or 1646886-04-A)
  • For all 4DU drive units use KAF1 (part number 1646886-02-A or 1646886-04-A)
