Aluminum thermostat housing M103 M104 engine Mercedes W202 W210 W126 W140 R107 R129 W463<\/h4>\n

This aluminium thermostat housing is a durable modification for the original plastic thermostat housing of the Mercedes M103 engine. The original plastic version is a known weak point and can crack due to aging, resulting in coolant leakage.<\/p>\n

With this aluminium version, this problem is permanently solved. The thermostat housing is much stronger than the original plastic part and is therefore ideally suited as a preventive replacement, during a cooling system overhaul, or in the event of a leak.<\/p>\n

      Advice for optimal protection of the cooling system<\/h5>\n

      For a long lifespan of the radiator, water pump, and other components of the cooling system, we always recommend using the correct coolant.<\/p>\n

      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.<\/p>\n

      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.<\/p>\n

        \n
      1. Protects radiator and engine against corrosion.<\/li>\n
      2. Prevents limescale and internal contamination.<\/li>\n
      3. Extends the lifespan of the radiator, water pump, and other components of the cooling system.<\/li>\n
      4. Reduces the risk of overheating and internal damage.<\/li>\n<\/ol>\n

        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.<\/p>","protected":false},"excerpt":{"rendered":"
