Common Signs Your Vehicle Needs a Coolant Flush
Most manufacturers recommend a coolant flush every 30,000 to 50,000 miles, but this can vary depending on your vehicle’s make, model, and driving conditions. If you frequently drive in hot weather or heavy traffic—common around Austin—your cooling system works harder and may need attention sooner. Neglecting this service can lead to reduced engine efficiency, increased wear, and even costly damage to components like the radiator or water pump.
There are several signs that your vehicle may be due for a coolant flush. Watch for temperature gauge fluctuations, visible rust or debris in the coolant, or an unusual sweet smell under the hood—these can all indicate contaminated or deteriorating coolant. In some cases, your heater may blow cold air even when the engine is warm, which can also point to cooling system issues.
Getting a coolant flush involves draining the old fluid, cleaning the system, and refilling it with fresh coolant to maintain proper temperature balance and prevent corrosion. It’s a relatively simple procedure that offers lasting protection for your engine and ensures smoother operation year-round.
