How often do coolants have to be changed?
In the cooling system, pH buffers and additives are gradually degraded and become less effective with time. We therefore recommend a complete change of coolant every three to four years. It is also strongly recommended to clean the cooling system and completely renew the coolant whenever the cooling system is repaired. This prevents rust, contamination and suspended particles remaining in the system leading to scale, corrosion and other damage.
