- Coolant changes are often overlooked as part of regular maintenance and almost always topped up with tap water. Just in the same way your kettle furrs up with limescale over successive uses, lime and other impurities are deposited overtime in your cooling system. This blocks the fine waterways in your radiator, and seizes your thermostat and water pump. These also promote oxidation, which is a particular issue with classic cars as the radiators and engine components are less resistant to rusting.
- MOTUL Radiator Clean is a product specifically developed to break down deposits left in the cooling system of cars due to evaporation, tap water contamination and sludge build up caused by infrequent coolant changes.
