Just a correction for the record - it appears that G12 is actually made by Valvoline (Zerex), although Pentosin makes a similar, and I believe compatible, coolant.

VW G12+ its pink and can mix with previous versions of VW coolant

GSF [1] do it for £4.50 for 1.5Litres (concentrate, makes double) Avoid non- recommended brands as the T25 WBX is prone to corrosion on parts that the coolant comes in contact with (i.e the bolts that hold your engine together.) If these corrode then when it eventually comes to change your cylinder head these are likely to snap and your engine will bassically need to be rebuilt.


It will take 9 litres of anti-freeze to fill your system (before diluting) = 6 bottles = £27.00 at GSF

Coolant volume = 16~18 litres

50/50 mix (ideal for max frost protection and ideal for corrosion protection too)



The VAG specification for G12+ antifreeze is TL 774-F

The VAG specification for G12 antifreeze is TL 774-D

The older, blue-green, VW G11 coolant has VAG specification TL 774-C


Mocki uses Comma Super Coldmaster - Concentrated Antifreeze. Comma have confirmed that this does not meet G12 spec but the xtream red does (however it is more expensive than G12+!)


From here:

A while back, I posted that G12 coolant was made by Pentosin.

Just a correction for the record - it appears that G12 is actually made by Valvoline (Zerex), although Pentosin makes a similar, and I believe compatible, coolant.

G12 is Valvoline/Zerex Glysantin G 30, the datasheet for which may be found at [2]

It was developed in conjunction with BASF, and more info on G12 is to be found at [3]

The VAG specification for G12 antifreeze is TL 774-D.

In January, 2003, VW/Audi introduced G12+ (part number G 012 A8F A4), an antifreeze with purple coloration. It can be freely mixed with the original pink G12 (part number ZVW 237 G12). The VAG specification for G12+ is TL 774-F. From the information at the above BASF site, Glysantin G 30 meets both specifications. I believe that the only significant difference between the two is the color - changed to help prevent people from thinking that GM Dexcool compatible (typically orange) coolant could be used to top-up the original G12 (pink), which is not the case.

The older, blue-green, VW G11 coolant has VAG specification TL 774-C, and is Glysantin G 48.
