What coolant does Tesla use?
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.
- 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]

Not sure which coolant your car takes?
Find your coolant →Colour and chemistry
Among the 2 products on this page, the listed colours are Blue (2), and the listed chemistries are not published. Colour is a dye chosen by each maker, so two coolants of the same colour can be chemically different, and the same chemistry can come in different colours. Match the spec or the named factory coolant, not the colour. See coolant colours explained and OAT vs HOAT vs IAT.
Topping up and mixing
If the reservoir is low, top up only with the coolant your manual specifies, and use the same premix or concentrate ratio. Mixing chemistries can reduce corrosion protection and shorten coolant life. Some makers (Mopar, Mercedes-Benz) explicitly say not to mix specs. If an unknown coolant has been added, a flush and refill is safer than topping up. Use the mixing checker and our coolant flush guide. Never open a hot radiator or reservoir cap.
Varies by model and year
Tesla has changed coolant specs over the years, and a spec can differ by engine and market (for example North America vs Europe). Electric and hybrid models may use separate loops with their own fluids. This page does not tell you which code applies to your vehicle. Your owner's manual, the reservoir cap label or a dealer does.
When to see a mechanic
See a dealer or qualified mechanic if the coolant looks rusty, oily or sludgy, if the engine overheats or the coolant warning light comes on, or if you cannot identify the correct spec. See coolant warning light and coolant leaks.
