The proportion of anticorrosion agent/anti
freeze in the cooling system should
• be at least 50 %. This protects the cooling
system against freezing down to about
37 °C.
• not exceed 55 % (frost protection down to
45 °C), as otherwise heat is harder to dis
sipate.
If the vehicle has lost coolant, top up with
equal parts water and anticorrosion agent/
antifreeze.
Always use anticorrosion agents/antifreezes
that have been approved by smart or offer
equivalent protection.
Information on this is available from any qua
lified specialist workshop, e.g. a smart center.
