Wynn's Radiator Stop Leak Cooling System Sealer 325 ml

Wynn's Radiator Stop Leak is a professional-grade additive formulated to seal minor leaks within automotive cooling systems. This 325 ml treatment is engineered to identify and plug small fissures in radiators, water pumps, and heating circuits, ensuring the integrity of the cooling loop. By maintaining a sealed system, it helps prevent coolant loss and protects the engine from overheating, which is essential for long-term vehicle reliability.

Advantages

The primary benefit of this formula is its ability to provide a reliable seal without the risk of clogging critical components like narrow radiator channels or heater cores. It is fully compatible with all standard antifreeze and coolant types, making it a versatile solution for various vehicle makes and models. The additive is designed to remain stable under high operating temperatures and pressures, providing a durable repair that helps maintain optimal engine thermal management.

Suitable for

• Sealing minor leaks in automotive radiators
• Repairing small fissures in water pumps
• Addressing leaks in vehicle heating systems
• Preventive maintenance for cooling circuits

This product is not intended for repairing large cracks, burst hoses, or significant structural damage to the cooling system. If the leak is substantial or if the cooling system is heavily contaminated with debris, mechanical repair or component replacement is necessary rather than using a chemical sealant.

Key specifications

• Volume: 325 ml
• Compatibility: All antifreeze and coolants
• Application: Cooling system leak repair
• Formulation: Non-clogging liquid

To use this product, ensure the engine is cool before opening the radiator cap or expansion tank. Shake the bottle well and pour the entire contents into the cooling system. Start the engine and allow it to run at operating temperature for approximately 10 to 15 minutes to ensure the additive circulates thoroughly and seals the leak points. Check the coolant level after the engine has cooled down and top up if necessary.

What to consider before purchase

• Verify that the leak is minor and not caused by a burst hose
• Check the total capacity of your cooling system
• Ensure the cooling system is not already clogged with scale or rust

For best results, use Wynn's Radiator Stop Leak as a preventive measure or for immediate minor leak repair. Always monitor your engine temperature gauge closely after application to ensure the cooling system is functioning correctly.
