Our coolant flush process reduces sediment buildup which can lead to corrosion in the coolant pipes and tanks and protects the metal surface of the radiator, hater core and engine block. A professionally conducted coolant flush lubricates the water pump, allows the cooling system to operate at maximum efficiency and reduces the likelihood of overheating and blown gasket heads.
Is a coolant flush really necessary?
Left unchecked, rust and particulate can block internal passageways which can cause a generator to overheat. Plus, the new coolant will contain fresh additives that will protect the interior of the engine and radiator from further corrosion.
Over time coolant properties change, becoming acidic (lower pH) and corrosive to certain metal engine components. But pH levels which are too high can cause aluminum surfaces in and around the radiator to corrode and damage critical engine cooling parts. Coolant with high pH levels can ‘eat’ through the thin tubes of the radiator core causing damage beyond repair and requiring a complete radiator replacement – a repair bill that may run into thousands of dollars depending on size.
Coolant also has lubricating qualities that diminish over time. This is important in maintaining the moving parts within the cooling system, such as water pumps. Old coolant with particulate and low lubricity can cause water pumps to fail and your generator to overheat and shut down.
A coolant flush also protects against foaming. Aged coolant can become frothy as it’s pumped through the system. Foamed coolant will not transfer heat away from the engine efficiently rendering the coolant ineffective and causing overheating.
How is a coolant flush performed?
The proper way to perform a cooling system flush is to first add a cleaning solution to the cooling system, the generator set is then run for about 15 minutes to ensure that the cleaning agents are properly circulated throughout the system. Next the system is drained of the old coolant. Fresh water is then rinsed through the cooling system and monitored until it runs out clean to ensure the removal of any remaining coolant, cleaning agents, and loose deposits. The system is then refilled with fresh coolant per engine/generator specifications.
It is additionally recommended that the thermostat and gasket be replaced during this service to ensure proper function.
What are the benefits of a coolant flush?
Aside from ensuring that your generator is operating at its peak performance and guarding against failed starts, coolant flushing can save you thousands of dollars when it comes to a radiator replacement which also comes with related downtime during the repair window.
