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.

Buy VW TL 774-G (G12++) coolant
As you can see in the table, the G12++ standard has already been replaced by the G13 and then VW G12evo. Thus, only the G12evo coolant is manufactured by Volkswagen. If you would like to buy a coolant with the VW TL 774-G release, you have to switch to other manufacturers. For this purpose, we have picked out three suitable products for you. Because they have the official approval, they can be mixed with other G12 coolants.
With the latest G12evo coolant, you can fall back on the original VW G12evo. Like its predecessor, the G13, this has a pinkish-pink color and is mixable with older standard, such as the VW TL 774-G. However, in order for the fluids to perform to their full potential, a whole coolant change is recommended. In addition to the original VW product, but also the Glysantin G65 has the latest VW release.
Radiator antifreeze is always available as a concentrate or ready-mix. The latter already contains a proportion of water, so that it can be filled directly into the cooling system. With the concentrate, however, you have to dilute it with water. Here you can orient yourself to a mixing ratio of 1:1. If you increase the proportion of water, the entire liquid can freeze faster at subzero temperatures. When diluting, you should use a distilled water, as it does not lead to lime deposits in the cooling system
