Fluids And Capacities: Fluids: Coolant

WARNING: This page is about a different car, the 2024 Tesla Model X, 2023 Tesla Model X, 2022 Tesla Model X, and 2021 Tesla Model X. However, it is still accessible from the selected car via links, so may be relevant.

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

For China only, please use the following coolant:

1012820-10-A, COOLANT, ETHYLENE GLYCOL, 50/50 MIX, 4L

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 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.

CAUTION: Tesla cannot provide warranties for any type of coolant other than Tesla G-48 coolant. Use of other coolants is at your own risk.
