VW TL 774-G Coolant
If you are looking for a coolant, you will often come across various abbreviations. Especially in the case of Volkswagen (VW) coolants. For example, the abbreviation VW TL 774-G stands for a coolant release, which is also known as G12++, among other things. In your vehicle manual you will find if rather the release VW TL 774-G, instead of the G12++. This is because the numerical release hides a certified standard. Only coolants that show such a release are then also suitable for your Audi, Volkswagen, Skoda or Seat, if according to the manufacturer a coolant with VW TL 774-G should be used.
Approval vs. recommendation
If you want to buy a coolant with the VW TL 774-G approval, you should always pay attention to whether a coolant also officially indicates this as an approval or refers to the fact that it is “recommended” for this purpose. The crucial difference in this case is that a coolant with the official release can be used without any problems. This means that you do not lose any warranty protection against the vehicle manufacturer. If you use a coolant with a recommendation, the warranty claim can be lost in the event of damage to the cooling system.
In terms of price, however, the coolants with a recommendation are usually cheaper, since the manufacturer has no further costs due to the official certification. This price advantage can then be passed on to the customer.
VW TL 774-G and the color
A much-discussed topic is the color of a coolant and that this is automatically accompanied by a release. However, it is wrong to say that a red coolant, for example, always corresponds to a G11 or G13 coolant. This is because every coolant manufacturer is free to decide which color to use for its coolant. A good example is the well-known manufacturer Glysantin. The red-pink Glysantin G40 has VW TL 774-G and Mercedes Benz MB 325.5 approval. Two different approvals, but one color.
