Advice for optimal protection of the cooling system
For a long service life of the coolant pump, radiator, and other components of the cooling system, we recommend always using the correct coolant.
For classic Mercedes models, this is usually a blue-green, silicate-based coolant that offers protection against corrosion, limescale, and internal degradation of the cooling system.
In addition, waterless coolant is an excellent alternative. It prevents internal corrosion, reduces the risk of boiling problems, and offers extra protection for classic engines.
Never reuse drained old coolant. Coolant is hazardous waste and must be disposed of in accordance with applicable regulations.
Always check before purchase and installation whether the part is suitable and equivalent based on photos, description, and specifications; installed or used parts cannot be returned.
