Protect your engine from freezing, overheating, and costly repairs

When temperatures start to drop in the fall, most drivers think about jackets and blankets—but your car needs protection from the cold, too. One of the most important (and overlooked) services is a coolant flush.

Coolant, also known as antifreeze, circulates through your engine to regulate temperature. Over time, it loses effectiveness and can even cause damage if left unchecked. Here’s why getting a coolant flush this fall is a smart move.

What Does Coolant Do?

Coolant is your engine’s temperature manager. It:

• Prevents overheating in summer
• Prevents freezing in winter
• Protects engine parts from corrosion and rust
• Keeps the heater working for those chilly mornings

When coolant breaks down, it can’t do these jobs properly—leaving your engine at risk.

Signs You May Need a Coolant Flush

• Temperature gauge running hotter than normal
• Rusty or discolored coolant fluid
• Heater not blowing warm air in cold weather
• It's been 5 years or 100,000 miles since your last coolant flush

If you notice any of these signs, it’s time to bring your vehicle in.

How Often Should You Get a Coolant Flush?

Most manufacturers recommend a coolant flush every 30,000–50,000 miles or every 2–3 years.

Driving conditions matter too—if you tow, drive in extreme heat/cold, or spend time in stop-and-go traffic, your coolant can wear out faster.

Why It’s Worth It

Skipping a coolant flush may not seem like a big deal, but dirty or weak coolant can lead to:

• Overheating
• Frozen or cracked engine block
• Corroded radiator and hoses
• Expensive repairs (sometimes thousands of dollars)
