Aluminum Radiator Repair Stic-Tite

The Northern Radiator Aluminum Radiator Repair Stic-Tite is a ready-to-use emergency sealant designed for automotive cooling system leaks in aluminum radiators. This portable repair stick is perfect for addressing pinhole leaks, minor weeps at seams, or unexpected failures during road trips, providing immediate containment without the need for coolant drain-down or disassembly.

This stick-format sealant works by chemically bonding to aluminum oxide surfaces, creating a waterproof plug that hardens under coolant circulation and engine heat. It is specifically formulated to withstand the thermal cycling, pH balance, and pressure demands of automotive cooling systems, ensuring that repairs hold through repeated heat cycles and prevent corrosion.

Aluminum radiator owners, from daily drivers to weekend track enthusiasts, will find this product invaluable, especially during extended trips or in remote areas where radiator repair shops are not readily available. The compact size of 6.2 x 0.65 x 9.1 inches makes it easy to store in a toolbox, glove compartment, or emergency kit.
