Rislone powder radiator stop leak protects cooling systems (July 28, 2010)

Rislone has introduced a powder version of its popular Radiator Stop Leak. The new product uses the same active ingredients as Rislone Liquid Radiator Stop Leak, but the powder comes in a small, easy-to-use tube.

Like its liquid counterpart, Rislone Powder Radiator Stop Leak (p/n 31170) is designed to permanently seal leaks in plastic, aluminum and metal radiators, heater cores, blocks, heads, gaskets and freeze plugs, including internal, external and coolant-to-oil leaks. These tiny particles will not clog heater cores. In addition to stopping leaks, Rislone Powder Radiator Stop Leak also protects the cooling system. It inhibits the formation of rust and scale, neutralizes pH imbalance, prevents electrolysis and lubricates the water pump seal.

One package treats systems up to 11 litres. Rislone Powder Radiator Stop Leak is safe for any cooling system using conventional green (silicate-based) and extended life red/orange or yellow (OAT) antifreeze. It is added directly to the radiator, with no flushing required.
