Penrite Radiator Flush - 375ml

Radiator Flush is a fast-acting (7 minute) alkaline cleaner formulated to remove rust, scale, and other deposits from automotive cooling systems that can restrict coolant flow through the radiator or engine. It is suitable for use in passenger cars, 4WDs, light and heavy-duty commercial vehicles, motorcycles, agricultural, mining, construction equipment, and stationary engines.

Designed to be used before adding new coolant, Radiator Flush thoroughly cleans the cooling system of rust and residue that could impair coolant performance. It also neutralizes any remaining old coolant to prevent compatibility issues when switching coolant types. The formula is safe for all metals, rubber, plastic, and seals commonly found in cooling systems. After flushing, refilling with a quality OEM-approved Penrite antifreeze and anti-boil coolant is recommended.
