Bluecol ‘U’ is a universal top-up antifreeze/coolant which is suitable for use in all vehicles (both petrol and diesel) and it will mix with all colours of antifreeze already in the radiator/expansion tank.
 
When Bluecol ‘U’ is added to antifreeze already in the cooling system, the synthetic process and additive package in Bluecol ‘U’ enhances and revitalizes the qualities of the original antifreeze, providing exceptional all year round protection and performance in all driving conditions.
 
Bluecol ‘U’ Antifreeze offers superior corrosion resistance over extended service periods, which can also be left in the system as a coolant and inhibitor against rust up to a maximum of 5 years.
