Your engine works hard—especially during those hot North Carolina summers—and your car’s cooling system is what keeps it from overheating. At Yeargan’s Automotive, we see a lot of preventable engine issues that start with a neglected cooling system. With just a little routine care, you can keep your vehicle running smoothly and avoid costly repairs.
Here’s what our team recommends to keep your cooling system in great shape:
💧 1. Check Your Coolant Level Regularly
Coolant (also called antifreeze) absorbs engine heat and keeps things running at the right temperature. If your coolant is low, your engine could overheat or suffer internal damage.
Quick tip from our techs: Check the coolant reservoir once a month when your engine is cool. If it’s below the recommended level, top it off with the correct coolant—or swing by the shop and we’ll check it for you.
🔄 2. Flush the System Every Few Years
Over time, coolant breaks down and picks up rust and debris. That’s why we recommend a coolant flush every 2 to 5 years (depending on your vehicle and driving habits).
A flush removes the old fluid and gunk, replacing it with fresh coolant that keeps your engine protected. If you’re not sure when your last one was, we’ll be happy to check your service records.
🧰 3. Inspect Hoses and Belts
Hoses carry coolant between your radiator and engine—and if they crack or leak, it can mean big trouble. Belts, like the one that powers your water pump, also wear out over time.
What to look for:
Cracks, bulges, or soft spots in hoses
Squealing or visible wear on belts
Leaks or dried coolant around clamps
If you notice any of these signs, come see us before they turn into a breakdown.
🌬️ 4. Keep the Radiator Clean
A clean radiator helps your car “breathe” better. Dirt, bugs, and debris can block airflow, making your cooling system less effective.
A gentle rinse or soft brush can help—but if your car's been running hotter than usual, let our team check it over and make sure there’s no deeper issue.
🚨 5. Pay Attention to Warning Signs
Here’s what might mean trouble is brewing:
Rising temperature gauge
Steam from under the hood
Sweet smell from the engine bay
Green, pink, or orange puddles under the car
If you see any of these, don’t wait. It’s always cheaper to fix a small leak than to replace a whole engine.
🛠️ 6. Use the Right Coolant (We’ve Got You Covered)
Different vehicles use different types of coolant—and mixing the wrong kinds can cause clogs and cooling issues. Not sure which one your car needs? No problem. At Yeargan’s, we’ll make sure the right fluid goes in your vehicle every time.
