Electrolysis Indicator™


The Kool-It Electrolysis Indicator™ is the easiest tool to visually determine if electrical electrolysis is present in ANY cooling system!
And it helps troubleshoot to find the source of the stray current too!


  • Diagnoses electrolysis instantly

  • Works in place of expensive meters

  • Place directly in radiator or reservoir if radiator access is limited

  • Green indicator light tells you everything is operating normal

  • Red indicator light tells you electrolysis is present

  • Also use to troubleshoot and find the source of the stray current



THERE ARE TWO DISTINCT TYPES OF ELECTROLYSIS IN VEHICLE SYSTEMS. KOOL-IT PRODUCTS ADDRESS BOTH TYPES!

1. The chemical type occurs in all vehicles and is a natural result when coolant (electrolyte solution) flows 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 the passage of time this very small amount of current (less than 0.3 volts) can cause damage to metal surfaces (especially aluminum). Given enough time, the damage will cause a leak to develop. KOOL-IT Supreme Coolant Treatment (P/N: 96001) provides long term protection from the chemical electrolysis damage by forming a passive, non-reactive, molecular surface film that prevents damage to the metal.

2. The electrical type of electrolysis is much more destructive and is caused by faulty electrical components that deliver stray current (over 0.3 volts) through the cooling system. This may be caused by a faulty ground or a shorted wire near the cooling system. Stray current introduced into a system this way can be strong enough to cause severe damage very 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 easiest solution to determine if the electrical type of electrolysis is present and troubleshoot where it’s coming from!
