Autochem 2 Year antifreeze & summer coolant is a methanol-free formulation suitable for all engine types, providing exceptional all-year-round protection and performance in all driving conditions. Autochem antifreeze is blended from an antifreeze concentrate which meets BS6580 (2010) and contains anti-corrosion additives which can be left in the system as a coolant and inhibitor against rust for up to a maximum of 2 years. Winter Protection: For general conditions, use a 33% v/v solution (1 part antifreeze to 2 part water). For optimum protection down to -18°C, use a 50% v/v solution (1 solution (1 part antifreeze to 1 part water). Directions for use: Drain and flush the cooling system with clean water. Check all hoses, clips and joints for leakage - tighten or replace where necessary. Refer to the vehicle manufacturer's handbook for the total volume of the cooling system. Remove the radiator cap and pour 1.5 litres of clean water into the radiator system. Add antifreeze to a volume equal to 33% or 50% of the total coolant system capacity (depending on the protection desired). Top up with clean water to the recommended fill level. Replace cap. Run the engine until it reaches the normal operating temperature to remove any air locks. Switch off the engine and allow to cool. Remove the radiator cap and top up with water if necessary. Replace cap. Note: If neat fluid is spilt on paintwork rinse off immediately with water. It is recommended to check antifreeze levels on a regular basis. If top-up is necessary, use Autochem antifreeze mixed to the same solution as previously used. When not in use, ensure the product is stored in a secure, upright position.
