Product Details
✓Ultimate 3-Step Cooling System Repair Kit: Includes Thoro-Flush, Ceramic Motor Seal, and All Weather Seal - three powerful additives designed to clean, seal, and protect your engine’s cooling system, radiator, and fuel tank. Ideal for vehicle maintenance, preventative repairs, and heavy-duty commercial use.
✓Step 1: Thoro-Flush for Rust & Scale Removal: This formula is designed to clean rust, scale, sludge, and grease from your engine’s cooling system. Restores coolant flow, unplugs heater cores, and removes gelled Dex-Cool and sludge in a single flush, improving coolant efficiency and engine performance.
✓Step 2: Ceramic Motor Seal for Durable Leak Prevention: Seals cracks, gasket leaks, and porous metal with a rock-hard ceramic coating. Trusted by performance enthusiasts for over 50 years to improve cooling performance by up to 10%. Provides a permanent seal that withstands extreme temperatures, perfect for head gasket leaks, intake gaskets, and cooling system cracks.
✓Step 3: All Weather Seal for Instant Leak Fix: No-plug formula blends seamlessly with your antifreeze to stop leaks in radiators, head gaskets, and more. Works when your engine reaches operating temperature, forming a patch over leaks. Compatible with all coolants, including waterless antifreeze, and suitable for all engine types—cast iron, aluminum, plastic, and more.
✓Premium Leak Protection for Every Engine Type: Ideal for use in automotive, commercial vehicles, and heavy-duty engines. Compatible with all antifreezes and metal surfaces. Provides a cost-effective solution to expensive engine repairs and helps prevent future breakdowns and coolant leaks.
✓Easy to Use : Each bottle in this 3-pack treats up to a 6-gallon cooling system. Follow the easy-to-understand instructions on each product for straightforward application. Whether you are dealing with rust buildup, overheating, or coolant leaks, this 3-step process restores your engine’s cooling system to optimal performance.
