Dodgy coolant warning

Tetrosyl warns that an influx of cheap coloured water has found its way into the UK market over the past couple of years which after testing, has shown to have little or no freeze rating. Its Bluecol and Carplan ranges of winter car care cleaning and maintenance products include antifreezes and coolants, screenwashes and wiper blades. Four new coolants have been added to the Bluecol range and are suitable for petrol and diesel engines. They prevent corrosion and overheating and offer protection from freezing down to -35ºC with a dilution rate of 50%.
