Cooling liquid |
mix of soft water and antifreeze (1:1), at such structure is provided frost resistance to –35 °C |
|
Antifreeze |
"G 012 A8D" (red color) or another, VW/AUDI-TL-774-D meeting standard, for example "Glysantin-Au-Protect/G30". It is allowed to apply "G12" (TL-VW-774-F) of lilac color. G12-lila antifreeze (lilac) can mix up with G12-rot antifreeze (red). On the 8-cylinder engine - only "G12 Plus" |
