The average life expectancy of a unit’s belts, hoses, thermostat and coolant is three to four years based on runtime and unit condition. Fidelity Power Systems^® suggests customers replace aging parts with new factory Original Equipment Manufacturer (OEM) parts to prevent any kind of system failure and maintain the system’s reliability.

Additionally, we offer a four-year extended life coolant, which reduces the overall cost of coolant replacement, including labor costs. Rehlko (formerly Kohler Energy) Genuine Coolant, with Hybrid Organic Acid Technology (HOAT), includes additives designed to extend the life of the unit components and improve overall operational efficiency.
