Understanding Your Cooling System’s Role in Preventing Overheating
Your car’s cooling system does more than just keep the engine from overheating—it manages heat transfer, protects against corrosion, and ensures optimal performance. Neglecting this system can lead to engine failure, one of the most expensive repairs you’ll face. With Arizona’s summer temperatures often exceeding 100°F, proactive care is essential. Here, we’ll provide practical steps to prevent overheating so you can drive safely and smoothly all season long.
5 Ways to Keep Your Car from Overheating This Summer
1. Use the Right Coolant
Not all coolants are created equal, and using the wrong one can spell disaster. Today’s modern vehicles require specific coolants tailored to their materials—aluminum, plastic, or specialized alloys. Always check your owner’s manual or consult with your trusted local mechanic to ensure you’re using the correct coolant. Avoid generic “one-size-fits-all” products from auto parts stores, as they may not meet your vehicle’s requirements.
2. Monitor Coolant Levels and System Pressure
Checking your coolant level is a must, but safety comes first. Always check the reservoir when the engine is cold (ideally in the morning before driving) as opening a hot radiator cap can result in severe burns from pressurized coolant. If the level is low, top it off with the correct coolant, but don’t stop there—low levels could indicate a leak or other issue. Our team at Good Works Auto Repair can perform a pressure test to identify hidden problems before they escalate.
To gauge system pressure, gently squeeze the upper radiator hose when the engine is cool. A soft, pliable hose is a good sign, while a hard, bulging hose suggests pressure buildup, indicating it’s unsafe to open the cap. If you’re unsure, let our professionals handle it.
3. Maintain Airflow for Optimal Cooling
Airflow is critical to your cooling system’s performance. Debris like bugs, dirt, or leaves can obstruct your radiator, transmission cooler, or AC condenser, reducing cooling efficiency. Regularly inspect and clean the front of your radiator, but be cautious to avoid damaging fins or electrical components. If you’ve added custom grills or had recent bodywork completed, ensure they don’t block airflow. A minor fender bender can also misalign components, so have your system checked after any accident.
4. Watch for Warning Signs and Act Fast
Your vehicle’s temperature gauge or warning light is your early warning system. If the gauge climbs toward three-quarters or a light appears, don’t ignore it. Pull over to a safe location, turn on the heater to draw heat away from the engine, and let the car cool down. Never drive further if the gauge hits the red zone—a mile too far can turn a small issue into a major repair. For vehicles with only warning lights, like some European models, treat any alert as urgent and seek professional help immediately.
5. Schedule Regular Cooling System Service
Preventative maintenance is your best defense against overheating. That’s why we recommend a full cooling system service every 2-3 years or 50,000 miles. This includes flushing old coolant, inspecting hoses, thermostats, and water pumps, and refilling with the correct fluid. At Good Works Auto Repair, we use advanced diagnostics to catch issues like sediment buildup or failing components before they cause trouble. Regular service not only prevents overheating but also extends the life of your engine.
