Specs and approvals listed by the manufacturer

  • Meets BS 6580 per Antifreeze is glycol plus inhibitors. Choose it by your vehicle's specification. (British Standard)

Manufacturer wording: PEAK® ORIGINAL EQUIPMENT TECHNOLOGY™ ANTIFREEZE + COOLANT for EUROPEAN VEHICLES - BLUE meets the performance requirements of ASTM D3306 and BS 6580.

"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.

What the manufacturer says it is for

Audi, Porsche & Volkswagen: Pre-1996 BMW & MINI: All, includes hybrid and electric vehicles Dodge Sprinter: All Freightliner Sprinter: Pre-2013 Jaguar: Pre-1997 Land Rover V8 & Diesel: 1990-2005 Mercedes-Benz: Pre-2014, includes hybrid vehicles

Quoted from the manufacturer's page. Coolant.com has not verified fitment for any vehicle, and a listed make or year range is the manufacturer's statement, not ours.

Compatibility notes

  • If your owner's manual calls for BS 6580, PEAK lists that code for this product. Read the exact wording above, and confirm against your manual.
  • Chemistry is listed as HOAT. Mixing different chemistries can shorten coolant life. See OAT vs HOAT vs IAT and use the mixing checker before topping up.
  • 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.
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.
