RXSOL REDCOOL is a complete full fill requirement and it’s ready to use - simply pour. RXSOL REDCOOL is a glycol premix coolant which reduces cavitation in areas such as the water pump and surface cavitation in hot spots of the cylinder head. The minimisation of cavitation erosion and pitting of heat rejecting aluminium surfaces (eg. behind exhaust ports) helps to increase component life. A concentration of at least 30% glycol is required to obtain a significant improvement in cavitation performance. Motor manufacturers normally use a minimum of 33% glycol coolant in new vehicles to achieve satisfactory engine cooling system protection.RXSOL REDCOOL is premixed to more glycol concentration. RXSOL REDCOOL will raise the boiling point and lower the freezing point of the engine coolant. The benefits impart a resistance to the engine coolant boiling in summer and freezing in winter. RXSOL REDCOOL incorporates additives to guard against corrosion of cast iron, steel, brass, solder, copper and aluminium alloys used for engine and radiator components.
