Related Repair Advice

  • Coolant testing strips are the recommended method for determining the amount of coolant additive that needs to be replenished
  • A supplemental coolant additive (SCA) will provide a continuous protective coating on the metal surfaces of the cooling system. This coating helps resist the effects of cavitation in the cooling system.
