Wynns Cooling System Flush is a specialized cleaning solution designed to remove rust, scale, and mineral deposits from automotive cooling systems. This effective 325ml formula contains powerful detergents and chelating agents that dissolve and suspend contaminants that accumulate over time, restricting coolant flow and reducing cooling efficiency. Regular use helps maintain proper engine operating temperature, prevent overheating, and extend the life of cooling system components including the radiator, water pump, and heater core.

Key Features

• Scale Removal: Dissolves mineral deposits and lime scale throughout the cooling system
• Rust Elimination: Removes rust and corrosion products that restrict coolant flow
• Sludge Dissolution: Breaks down accumulated sludge and sediment
• Heat Transfer Restoration: Improves cooling efficiency by cleaning heat exchange surfaces
• Water Pump Protection: Removes abrasive particles that can damage pump seals
• Radiator Cleaning: Clears restricted radiator tubes and fins
• Heater Core Restoration: Improves cabin heating by cleaning restricted heater cores
• Compatible with All Coolants: Safe for use with all types of antifreeze and cooling systems
• Non-Acidic Formula: Won't damage aluminum, copper, or plastic components
• Preventative Maintenance: Recommended before each coolant change

How to Use

Add entire contents to the cooling system when the engine is cool. Top up with water if necessary to ensure proper level. Run the engine at normal operating temperature with the heater set to maximum for 10-15 minutes. Allow the engine to cool completely, then drain the entire cooling system according to manufacturer's instructions. Flush thoroughly with clean water until it runs clear. Refill with fresh coolant of the appropriate type and concentration. For severely contaminated systems, a second treatment may be necessary.

Cooling System Flush is particularly valuable for preventative maintenance in older vehicles or those with high mileage where scale and deposit buildup is more likely. This product should be used as part of regular cooling system service every 2 years or 30,000 miles, or whenever coolant is changed. For cooling systems contaminated with oil, use Wynns Extreme Cooling System Degreaser first, followed by this product. Regular use helps prevent cooling system failures, extends component life, and ensures consistent engine operating temperature.
