🔍 Understanding the Basics
When it comes to protecting your engine during the scorching Tennessee summers, few systems are more important than your cooling system. Many drivers use the terms coolant and antifreeze interchangeably, but they’re not exactly the same — and knowing the difference can save you from costly repairs.
🧪 What Is Antifreeze?
Antifreeze is a concentrated liquid, typically made from ethylene glycol or propylene glycol, that’s designed to:
-
❄️ Lower the freezing point of engine fluid in winter
-
🔥 Raise the boiling point to prevent overheating
-
🛡️ Protect the cooling system from rust, corrosion, and mineral deposits
It’s important to note that antifreeze must be mixed with water to be used safely inside your vehicle.
💧 What Is Coolant?
Coolant is a 50/50 blend of antifreeze and distilled water. It is this mixture that flows through your engine block, radiator, and hoses, absorbing excess heat and keeping your engine operating at safe temperatures.
Without the correct type and concentration of coolant, engines in Hendersonville, Gallatin, and across Sumner County can quickly overheat — especially in summer conditions.
⚠️ Why Coolant Maintenance Is Critical
Coolant deteriorates over time. Exposure to extreme temperatures, metal surfaces, and contaminants can lead to:
-
Acidic breakdown
-
Sludge and rust formation
-
Blocked radiator or heater core
-
Failed thermostat or water pump
This breakdown can lead to engine overheating, poor AC performance, and eventual engine damage if not addressed.
🔧 What Is a Coolant Flush?
A coolant flush is a preventive maintenance procedure where:
-
Old, contaminated coolant is completely drained
-
A cleaning solution is run through the system to remove deposits
-
Fresh coolant is added to restore thermal protection
This process helps ensure proper flow, optimal temperature regulation, and extended component life.
🌞 Why a Flush Is Essential Before Summer
Tennessee summers are brutal — and your engine feels it. With ambient temps soaring and more people on the road, your vehicle’s cooling system works overtime.
A coolant flush ensures:
-
🚗 Faster heat transfer and cooler engine temperatures
-
🔧 Improved system efficiency
-
🧰 Protection against high-temp breakdowns and costly repairs
Hendersonville Muffler and Brakes recommends flushing your coolant every 30,000 to 50,000 miles, or every 2–3 years depending on your make, model, and usage.
