tifr ee
ze protection will diminish and this will
worsen cooling.
When the coolant is topped up, use a mixture
of distilled water and at least 40 % of the
additive G12evo for optimal protection
against corrosion. Mixing G12evo with G13
(TL-VW 774 J), G12 plus-plus (TL-VW 774 G),
G12 plus (TL-VW 774 F), G12 (red) or G11

If there is not enough anti-freeze in the
