Deposits in the cooling / heating system form a barrier to heat exchange, block thermostatic valves and regulating mechanisms. At high engine temperatures allow the engine to run economically with a high wear and high risk of damage. Radiator Cleaner removes these dangerous deposits safely and ensures optimal engine temperature and reliability. Application:.
