Quick answer
Tesla coolant: Tesla specifies Tesla G-48, a phosphate- and nitrate-free ethylene-glycol 50/50 premix (do not add water). Tesla warranties no other coolant, and advises owners to contact Tesla service rather than topping up themselves.

What coolant does Tesla use?
- Tesla's Model 3 service manual says the cooling system "contains an ethylene glycol (phosphate and nitrate free) based coolant". It lists 1029320-00-A (50/50, 1 gal) for North America and 1119779-00-A (G48, 50/50, 1 l) for EMEA. [1]
- "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." [1]
- "Tesla cannot provide warranties for any type of coolant other than Tesla G-48 coolant." The manual adds that LC100 (blue) coolant from Gigafactory Shanghai "can be mixed with G48 (blue) coolant as needed". [1]
How Tesla coolant changed over the years
Tesla is the odd one out. There is no engine, and the coolant loop cools the battery and drive electronics [1]. For most owners it is not a service item at all [2].
