The radiator and cooling system in your vehicle holds a water and antifreeze mixture called Permeant Coolant/Antifreeze to help your engine maintain proper temperature and provide heat and defrost functions. The mixture prevents your vehicle from overheating in the summer, and prevents the engine from freezing during the winter. The amount of permanent coolant required varies from vehicle to vehicle.

Radiators, cooling & heating systems require Cooling System Flushes from time to time because the by-products produced during normal wear and tear of the system and the decay of the chemical mix in the permanent coolant can dirty the system with impurities and rust. These particles can block the system and prevent the radiator from performing the way the engine requires. It may also reduce the amount of heat available to heat the cabin and defrost the windows. By flushing and servicing the system, you will help extend the life of your vehicle and prevent costly breakdowns and repairs.  

When to Get a Radiator Flush

There is no set rule for how often you should get your radiator flushed. The frequency of radiator flushes will depend on several factors, such as your own driving habits and the quality of antifreeze you use. Occasionally flushing your car's radiator will help extend the useful life of your vehicle.

Over time, the antifreeze in your vehicle may become acidic and lose its ability to help protect the engine from extreme temperatures. You can purchase a pH level litmus test at your local auto parts store to test the acidity level of the antifreeze. Simply insert one of the litmus test strips into your car's radiator and refer to the color guide on the box. If the test reveals that the water and antifreeze in your radiator is too acidic, then it's time to get a radiator flush.

While there is no set schedule for getting a radiator flush, almost all car manufacturers recommend that you drain and refill your radiator with quality antifreeze at least every other year, or every 40,000 to 60,000 miles - whichever comes first. Occasionally flushing the radiator will help keep it clean and prevent buildup of dirt and sediment. Fresh antifreeze will also help protect your car engine from extreme cold or hot temperatures.
