Your vehicle’s engine works so hard and, in the process, gets too hot that it could melt into a block if not cooled down. The coolant or radiator fluid keeps the temperature down to ensure that the engine is operating optimally. The fluid moves the heat away from the engine to be more effective on the Naperville, IL roads. However, coolant fluid exchange is vital for the health of your car’s engine. It extends the life of the components in the cooling system by removing contaminants and preventing rusting.


The coolant flush or radiator fluid exchange is the process of draining the old and tired fluid and replacing it with a fresh one for your vehicle. The constant high temperatures from the engine break the radiator fluid over time. This process produces acids that inhibit effective heat dissipation and damages the cooling system. That is if you fail to exchange the coolant fluid. The fluid exchange ensures that the coolant is doing its job to protect the engine and ensure your vehicle is effective. It also removes any acid built up since the last exchange to prevent corrosion of the engine parts.


A fresh, coolant fluid extends the radiator’s life and reduces the overall repair costs you incur. The new coolant contains chemicals that slow down any rusting or corrosion of the cooling system. But how often should you exchange the fluid? Whether you are driving in Aurora, Bolingbrook, Wheaton, or Woodridge, some vehicle manufacturers recommend changing the engine coolant after every 30,000 miles. Hyundai advises 60,000 miles and 30,000 miles after that. For vehicles subjected to severe service, the engine coolant exchange should be more often.



Modern vehicles come with engine coolant with longer intervals between changes. The coolant still deteriorates over time, and it’s hard to tell by its appearance. A coolant flush and antifreeze drain may be necessary even if the antifreeze and coolant protection levels are adequate. At Bill Jacobs MINI in Naperville, IL, we test the acidity and the freezing and boiling protection of the coolant, periodically, after the vehicle achieves 50,000 miles. We check the PH level using test strips. If the acidity is high, we use a flash machine to exchange the old with the new fluid at the same time. Our experienced and qualified technicians are more than happy to handle any vehicle maintenance and care needs.
