How to Prevent Your Car from Overheating

How to Prevent Your Car from Overheating

Few car problems are as stressful and damaging as an overheating engine. Whether you're stuck in summer traffic or driving up a steep hill, temperature spikes can lead to costly repairs if not managed quickly. Fortunately, with the right care and preventive habits, you can avoid most overheating situations. Here's how, straight from the experts at DM Motorsports in Midland Mint Hill, NC.

1. Regularly Check Your Coolant Levels to Avoid Overheating

Coolant (also called antifreeze) plays a vital role in regulating your engine's temperature. Always ensure your coolant reservoir is filled to the proper level.

• Check it monthly, especially in summer

• Only check coolant when the engine is cool

• Top off with the correct 50/50 coolant-water mix

2. Maintain the Radiator System

Your radiator helps dissipate heat from the engine. Keeping it clean and functional is key.

• Flush your radiator every 30,000 miles or as recommended

• Remove debris and dirt from the front of the radiator

• Replace the radiator cap if it no longer holds pressure

3. Inspect Belts and Hoses

Over time, belts and hoses can crack or wear down, causing coolant leaks or loss of circulation.

• Look for bulges, leaks, or cracks

• Replace belts every 60,000–100,000 miles

• Ensure hose clamps are tight and corrosion-free

4. Keep an Eye on the Temperature Gauge

Your car’s dashboard temp gauge is the first sign something’s wrong. If it starts creeping into the red:

• Turn off the AC and turn on the heater to draw heat from the engine

• Pull over and let the engine cool

• Do not remove the radiator cap when hot

5. Stay on Top of Preventative Maintenance
