What is a cooling system flush?
A cooling system flush, otherwise known as a coolant flush or radiator flush, involves the complete removal of fluid from the system. During normal cooling system service, coolant is drained and then replaced. However, this process only removes about 50% of the fluid from the radiator. It also does nothing to clear out the built-up scale deposits and debris.
During a full coolant service at Medi-CAR, a flush machine is used to completely clear the system of fluid. Our technicians refer to this as a cooling system “exchange.” Along with the coolant, any accumulated waste is flushed out of the system.
Our professionals then go in and use BG flushing chemicals to scrub the system clean. Next, BG additives and conditioner are used to prolong the life of the system and protect against future corrosion. Finally, the system is refilled with fresh, premium coolant.
What are the benefits to a coolant flush?
The biggest benefit is removing old coolant before it has a chance to become acidic. Similar to a vehicle’s oil, coolant breaks down over time. Antifreeze specifically can become acidic if it is not periodically replaced. If not properly serviced, old and broken down coolant can cause other parts of the vehicle to break down, wear prematurely or corrode.
A coolant flush also extends the life of your cooling system. The additives and protective lubricants in coolant are designed to protect the water pump and radiator. As these properties age, they’re less able to do their job. By flushing the system, you’re ensuring clean, functional additives are flowing through the engine.
