G12 concentrate for year-round cooling-system protection.
GEOSIM G12 antifreeze is a red 1 L concentrate for automotive cooling systems. Mixed with distilled water to the ratio you need, it protects the engine against freezing in winter and overheating in summer.
Concentrate rated down to -70°C
GEOSIM G12 comes as a concentrate rated at -70°C, so you set the mixing ratio with distilled water to match your climate and the carmaker's recommendation. One litre is enough for a top-up or for preparing a larger batch of ready coolant.
G12 spec in red for easy identification
The red colour of GEOSIM G12 marks the coolant's specification and makes it easy to spot in the expansion tank when checking the level. Always top up with the G12 class specified for your vehicle.
Handy 1 L bottle for the boot
The 1 L GEOSIM G12 bottle takes up little space and works well as a spare in the boot or the garage. Keep it for periodic top-ups after checking the coolant level.
