Do not dilute below 40%. Blue Star will protect for a maximum of 2 years and contains a bittering agent to help prevent ingestion. Methanol-free formulation suitable for all engine types.

If sludge is evident use Carlube Radiator Flush for a complete cooling system preparation. Check all hoses, clips and joints for leakage. Tighten or replace where necessary. Remove radiator or expansion tank cap, fill the radiator with antifreeze to give the level of protection required (refer to the vehicle handbook for total volume of the cooling system). Replace cap. Run engine until it reaches normal operating temperature to remove any air locks. Switch off engine and allow to cool. Check for and correct any leaks. Top up with water if necessary.
