An efficient cooling system is essential for any vehicle, and a coolant failure can spell the fast end of an engine with all the high costs that involves. Our radiator stop leak products can plug tiny cracks in the metal parts of the cooling system before they turn into engine-threatening leaks, helping you avoid the expense and hassle of a major radiator repair or replacement.

How Does Radiator Stop Leak Work?

Our leak stop range is made up of concentrates that are added to the cooling system along with the water and antifreeze. The concentrates contain added particles that are forced into any cracks when the system is under pressure, and then harden in the heat to create a tough seal that prevents the leak from growing.

They should be added at the first sign of a coolant leak. This could show up as a greenish liquid appearing on your garage floor or driveway. Alternatively, stop leak fluids can be used as a preventative measure and added every time the cooling system is flushed and refilled.

Different kinds of stop leak products are available to repair different parts of the vehicle’s cooling system, and if used early enough, can stave off more serious problems. If needed, radiator and engine sealer concentrates can be used repeatedly to keep small leaks under control, with a typical repair lasting for 10,000 miles or more of driving. However, if any visible leakage remains after treatment, it's important to book a car service appointment for a more lasting repair by a qualified mechanic.

Advanced Head Gasket Repair Seals

If you don't catch a radiator leak in time, one of the most common problems caused by overheating is damage to the engine's head gasket. A blown head gasket used to mean costly engine repair, but our head gasket repair formulas can stop minor leaks and seal cracks with a tough, permanent ceramic-type bond.

Use a Tank Repair Kit for Fuel Tanks or Fluid Reservoirs

It's not only the cooling system that can develop a leak in a vehicle. A tank repair kit can be used to seal cracks in both metal fuel tanks and plastic fluid reservoirs, stopping dangerous leaks and extending the life of the tank without needing welding or other major repairs. Our tank repair kits are used on an empty tank and require as little as a half hour for the resin to set into a solid bond, after which the repair is complete, and the tank can be refilled.
