Add one dosage Forté Cooling System Flush to the cooling system of a vehicle or 10 % by volume at larger cooling systems.

Run the engine op operating temperature and run on increased idling speed for 20-30 minutes, whilst the valve for the internal heating and thermostat are opened. Drain the coolant and flush the radiators and the complete engine with plain water. Make sure all the corrosion and scale formation is removed from the cooling system before refilling the cooling system.
As an after treatment we advise to add Forté Cooling System Conditioner to the new coolant to prevent corrosion and scale formation.
