Simply put, it’s the tried-and-true fast, effective, easy-to-use powder formula radiator stop leak that’s just as simple for a regular driver as for an experienced mechanic. Convenient solutions to seal coolant leaks shouldn’t be limited to just those with advanced automotive knowledge, which is why each product in our catalog is designed to meet the needs of anyone who gets behind the wheel of a vehicle. DIRECTIONS (IMPORTANT NOTE: Cooling systems that are dirty or partially clogged should be flushed before use): Allow engine to cool so radiator cap can be safely removed. Shake well and pour directly into radiator. Do not pack pellets in radiator. Pellets may be pre-dissolved if necessary by putting them in hot water. Note: If you don’t have access to radiator, remove top hose where it connects to top of radiator and install product in hose. Reattach hose and tighten clamp. Fill radiator and overflow tank to proper level, reinstall radiator cap and drive or idle engine for 15 to 30 minutes. Leave product in cooling system for preventative maintenance. Use once per year to help guard against future leak development. Review: Saved me thousands!! - I own a 2003 Ford Ranger four-cylinder. My radiator developed a slow drip. But don’t let a slow drip, fool you! Cruising down the highway my engine started to overheat and I had to pull off onto the shoulder as this slow drip rapidly drained my radiator! Not wanting to spend what could be thousands. I spent a few bucks on this product with nothing but amazing results! I could not access my radiator, so I dissolve the product and poured it into the reservoir as instructed. It did take a couple applications but now I have utmost confidence that I won’t have to pull off the highway again and it has completely sealed the leak! Thank you, thank you thank you!
