A coolant system flush (a.k.a. coolant flush or radiator flush) is an important element of your vehicle's preventative maintenance schedule. Most car manufacturers recommend getting a coolant flush every 40,000 miles or so (depending upon the vehicle) in order keep your engine performing at optimal levels. So what exactly is a coolant flush, and how will it benefit your vehicle? Read below to find out more. 

What is a Cooling System Flush? 

When the ASE Certified Technicians and Mechanics at Hogan & Sons Tire and Auto perform a cooling system flush, the first step they take is to remove all of the antifreeze (a.k.a. engine coolant) out of your car's system. During a typical cooling system service, the engine coolant is simply drained and then replaced, but this is not the same thing as a cooling system flush. When our certified technicians perform a full flush, they use a specialized machine to completely clean your radiator of any built-up sludge, dirt, rust, and any old antifreeze that has become corrosive to the engine. Once this cleaning (sometimes called a "transfusion") takes place, they apply several special additives that will keep the system clean, guard against corrosion and prolong the life of your engine. Lastly, fresh new coolant is added to the engine, giving it "new life." 

What Are the Benefits of a Cooling System Flush?
Antifreeze, like the other fluids in your engine, can become dirty after a while, which decreases its performance and poses a risk to the health of your engine. The chemicals in the average antifreeze formula have certain pH levels that must be maintained, but over time, these chemicals become depleted due to high engine heat and miles driven. This means that your engine loses a little bit of its protection, which can eventually lead to leaks or even failure of certain engine parts. Without this vital protection being there, your car engine can overheat, which is never a pleasant experience. In addition, old or broken down antifreeze can change the ratio of water to coolant in your engine, which means that on extremely cold days, the water in your engine can freeze and possibly crack certain parts of your engine. Keeping your vehicle serviced with a regular coolant system flush can prevent costly damage to your engine.

In addition, a coolant system flush will also extend the life of your engine's cooling system. There are certain lubricants and additives in your coolant that will protect the radiator and the water pump from damage. Over time, these parts can become worn down, but as long as you keep your cooling system flushed on a periodic basis, you will enjoy much more life out of your engine.
