This exclusive kit includes Thoro-Flush, Ceramic Motor Seal, and All Weather Seal, three high-performance additives trusted by professionals and enthusiasts for over 60 years. Whether you’re dealing with rust, scale, leaks, or sludge, this 3-pack provides the ultimate protection for your vehicle’s radiator, head gaskets, and cooling system. Thoro-Flush is the most powerful coolant flush available, designed to remove rust, scale, oil, and grease from your cooling system. Its formula is ideal for use on cast iron, aluminum, brass, and plastic, ensuring thorough cleaning without damaging sensitive components. Ceramic Motor Seal is a premium product that provides a permanent seal for gasket leaks, porous metal, and small cracks. This product coats the entire cooling system with a ceramic layer that improves coolant flow and helps your engine maintain optimal temperature control. It seals head gaskets, intake gaskets, and other engine components, reducing the risk of leaks and coolant loss. All Weather Seal is the ultimate leak prevention additive that works with all types of antifreeze, including waterless antifreeze. It blends seamlessly with your coolant and activates only when heat and air are encountered, sealing leaks in your engine’s radiator, head gaskets, and other cooling system components. The no-plug formula ensures that it won’t cause clogs or affect the performance of your heater core. This makes it ideal for both preventative maintenance and emergency repairs. Each product in this kit is designed to treat up to a 6-gallon cooling system. For best results, use the products in sequence, starting with Thoro-Flush, followed by Ceramic Motor Seal, and finishing with All Weather Seal for complete leak protection and system restoration. ## Features - 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.

Thanks.** A: It is meant to be a 3-step process, however, depending on your circumstances it could be beneficial to skip any one or more of these products. Certain types of leaks make using Ceramic Motor Seal dangerous to your engine. (coolant leaks that go to oil for example.) In such a case using All Weather Seal and not using Ceramic Seal would be advised. The Thoro-Flush is only if your system is in need of flushing to start with as clean of a system as possible, but in some cases may not be necessary. **Q: Should the thermostat be removed during flush and or ceramic seal procedure?** A: We recommend leaving the thermostat in during treatment because it will cause pressure to build which will aid and benefit the sealing or cleaning process. In addition to building pressure in the cooling system, peak performance is obtained with Irontite Coolant Additives, including ThoroFlush, when the engine is at normal operating temperatures, controlled by the thermostat opening/closing. **Q: What color is the red bottle, ceramic sealer liquid inside? Iooks different than last time I got some. Thank you** A: Gray in color **Q: What color is the liquid inside it? Iooks different than last time I got some. Thank you** A: It's a dark grey for Ceramic Motor Seal and more Black'ish for All Weather Seal and Thoro-Flush is a light Green. These colors will vary in intensity from mix to mix as we add the color in and since it's not a critical component of the mix it can vary a bit. ## Frequently Bought Together - Irontite 3-Pack Cooling System Additives - Thoro-Flush, All Weather Seal, Ceramic Motor Seal - Premium Leak Sealants, Rust & Scale Removers, Preventative Maintenance for Radiators, Head Gaskets & More - Irontite All Weather Seal, Blue, 16 oz - Irontite Thoro-Flush Coolant System Cleaner - Removes Rust, Scale, Oil, Sludge & Gelled Dex-Cool - 16oz Powder - Cleans Cooling Systems, Restores Coolant Flow, Safe for Cast Iron, Aluminum & Plastic --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/302077971-irontite-3-pack-cooling-system-additives-thoro-flush-all-weather](https://www.desertcart.pl/products/302077971-irontite-3-pack-cooling-system-additives-thoro-flush-all-weather) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-24*
