Specs and approvals listed by the manufacturer

  • Meets Tesla G-48 per Antifreeze is glycol plus inhibitors. Choose it by your vehicle's specification. (Tesla)

Manufacturer wording: Tesla Model 3 (2024+) service manual: "Tesla cannot provide warranties for any type of coolant other than Tesla G-48 coolant. Use of other coolants is at your own risk."

"Meets X per manufacturer" is our shorthand for any of the manufacturer's own phrases: meets, meets or exceeds, approved, or recommended for applications requiring. It is the manufacturer's claim, not an approval by Coolant.com or by the vehicle maker. Codes are copied as published. Some sources list codes for compatibility rather than formal approval. The wording above shows which.

Compatibility notes

  • If your owner's manual calls for Tesla G-48, Tesla lists that code for this product. Read the exact wording above, and confirm against your manual.
  • Colour is listed as Blue. Colour is a dye, not a spec, so two coolants of the same colour can be different chemistries. See coolant colours explained.
  • Sold premixed: pour as supplied. Do not add water unless the label says to.

Note: Tesla service manual, Model 3 2024+. Tesla advises owners not to add coolant themselves; contact Tesla service.

Always check your owner's manual first. Use the coolant spec printed in your owner's manual or service information. A listing here is the manufacturer's own claim (meets, exceeds, approved or recommended, worded as they put it). It is not our approval and not a fitment guarantee for your vehicle. If in doubt, ask your dealer or a qualified mechanic.
