Every 4cyl TDI has it printed on the coolant bottle. These two coolants are NOT compatible, and cause cooling system degradation.Įvery water cooled Volkswagen since the late '80s has, somewhere under the hood, a tag that specifies what coolant the car uses. Toyota specifies the red as "Long Life" and the pink as "Super Long Life", or SLL. Toyota's red coolant was replaced YEARS ago, the running change started around 2004-2006, depending on model/plant, with a prediluted pink coolant. All of these have been in older cars, and those same brands now use the Asian blue stuff. There ARE coolants that are blue-green, as used in some Hyundai/Kia products, some Nissans, and some Hondas. I should also add, that G11 is inky blue, it is NOT "blue-green".
Never use a coolant for Asian cars in any VW product. Euro spec coolants DO NOT contain phosphates.
They also contain silicates but so do Euro spec HOAT coolants. That's why I included the Asian coolants. The take away here is that not all HOAT coolants are created the same. An OAT coolant that contains phosphates is technically a HOAT coolant. Asian specification coolants are PHOSPHATED OAT coolants. OAT technology with a small amount of silicates added.Īsian Blue & Asian red are the exact same coolants except for the color. G05: a HOAT coolant that is basically the same formula as G12++. Non-OAT formula, contains borates, phosphates, and silicates. G48: The old VW G11 formula, the green/blue stuff. The amount of glycerine based glycol is around 10% of the total glycol content. All G13 is VW specifies a little bit of glycol derived from glycerine instead of 100% petrochemical based. Don't get all hung up on G13, it's not that special. The hybrid means some silicates were added. G40: VW G12++ and G13 compatible, HOAT (Hybrid Organic Acid technology). The first OAT (Organic Acid Technology) coolant This includes anything made by Prestone and Peak. A very brief description of each coolant starting from left to right.ĭex-Cool: Run away from anything that has Dex-Cool on the label. Not all NAPA stores stock all the varieties of Zerex coolant. This is the first time I saw all the Zerex products together. I took this photo at a NAPA store a few months ago. Contains some silicates and glycerin made from renewable sources as a substitute to some of the ethylene glycol. Contains silicates, borates, and nitrates. They talk about VW coolants around the 10 minute mark. Please verify any information in question with a sales representative.I can demystify all the confusion about VW coolants.
