Kool-It Electrolysis Indicator features the patented Kool-It electrolysis indicator. It is the easiest solution to visually diagnose the destructive excess stray current levels in cooling systems, known as "electrolysis". There are two types of electrolysis: a chemical type and an electrical type. The chemical type is a natural result of coolant (electrolyte solution) flowing through a system composed of different types of metals (iron, copper, or brass). The coolant acts as the conductor through which small amounts of current are transferred between metals in the cooling system. Over time, this very small amount of current (less than 0.3 volts) can cause damage to metal surfaces (especially aluminum). Given enough time, electrolysis will cause a leak to develop. The electrical type is much more destructive and is caused by faulty electrical components that deliver a stray current (over 0.3 volts) through the cooling system. This may be caused by a faulty ground or a wire shortage near the cooling system. The installation of aftermarket electronics, even factory equipment, can cause this type of electrolysis. The stray current introduced into a cooling system this way can be strong enough to cause severe damage quickly. The only way to prevent damage from this type of electrolysis is to mechanically correct this problem at the source. The Kool-It electrolysis indicator is the solution to determine if the electrical type of electrolysis is present. If the tool is dipped into the radiator, or radiator reservoir, a red light will confirm if electrolysis is present. Troubleshooting can be done with all systems on (AC, radio, etc.) and they can be shut off one by one shut to locate the culprit.
