Welche kühlerflüssigkeit für citroen c4 grand picasso?

Which information you need…

The car is from 2009 and the cooling fluid must be changed every three years.

So it has been changed several times or not…

After a long period of time, it cannot be certain whether silicate-free or silicate-containing coolant has been used and it cannot be reliably recognized by the color, which is NOT standardized.

If one would accidentally mix silicate-containing cooling liquid with silicate-free cooling liquid, then a chemical reaction with acid formation could occur which leads to expensive damage….

Therefore, leave the cooling liquid completely, fill in clear water once and leave it off and then mix new coolant from water and glysantin G33.

Please don’t just fill in water, because then you may not have any space for frost protection and if you first fill frost protection, the mixing ratio may not be right….before mixing in a one or pouring can in the right ratio is a safe solution.

If you have mixed too much, fill it in a clean canister and use it when you have to refill coolant.
