Stop the Steam: How to Keep Your Car from Overheating

Few things are as stressful as seeing that temperature gauge shoot up or, worse, seeing steam pour out from under the hood. When your car overheats, it’s not just an inconvenience—it’s a serious threat to your engine that can lead to costly damage. Understanding the causes and, more importantly, the solutions is key to keeping your ride running smoothly and your wallet safe.

At Matt’s Automotive Service Center, a family-owned and operated business with a commitment to excellence in the Fargo-Moorhead and Minneapolis-St. Paul, we believe in helping you prevent problems before they start. Our goal is to set a new benchmark in the industry by being much more than a typical auto repair shop. We want to be your trusted resource.

How to Keep Your Car from Overheating with Regular Maintenance

The best defense against an overheating engine is a great offense—regular maintenance. Your car’s cooling system is a complex network of parts, and neglecting just one can cause the whole system to fail. If you’re asking, “Why is my car overheating?” the answer often comes down to one of these areas:

The Cooling System: Your Engine’s Best Friend

The cooling system’s job is simple: remove excess heat from the engine. It circulates a mixture of water and antifreeze (coolant) through the engine block to absorb heat, then moves it to the radiator to cool down, and then back again. When this cycle is broken, you have a problem.

Cooling System Repair and routine checks are non-negotiable for long-term engine health. Here are the core components you need to keep an eye on:

• Coolant (Antifreeze) Check: Coolant is the lifeblood of the system. Check its level regularly—when the engine is cool! Low coolant is one of the quickest causes of an engine getting too hot. This is a simple yet vital step in engine cooling system maintenance.
• Hoses and Belts: Over time, the rubber hoses can become brittle, cracked, or soft, leading to leaks. A broken belt (like the serpentine belt) can stop the water pump from working, which means no coolant circulation. Have a skilled and dedicated auto mechanic inspect these during every oil change.
• The Radiator Cap: This small, often overlooked part maintains the pressure in the system. If the cap is faulty, the coolant can boil at a lower temperature, leading to overheating. A quick check of the seal can prevent a major headache.
• The Thermostat: The thermostat controls the flow of coolant. If it gets stuck closed, coolant can’t circulate to the radiator, and your engine will overheat quickly. This often requires professional cooling system repair.

Radiator Maintenance: The Heat Dissipator

The radiator is the star of the show when it comes to cooling. It uses air flow to remove heat from the coolant. If the radiator is clogged, dirty, or leaking, it can’t do its job.

Follow these essential radiator maintenance tips:

1. Flush the System: Over time, sediment and corrosion can build up inside the radiator and the engine’s coolant passages. A professional cooling system flush removes these contaminants and replaces the old, tired coolant with fresh fluid. We recommend doing this according to your car manufacturer’s schedule.
2. Keep it Clean: The outside of the radiator can get blocked by bugs, dirt, and road debris, especially during summer driving. Less airflow means less cooling. A quick, gentle spray can clear away the grime.
3. Check for Leaks: Visible leaks (puddles of sweet-smelling fluid) or rust spots on the radiator are clear signs you need immediate attention from specialized car technicians.

How to Keep Your Car from Overheating During Hot Weather

Summer heat is brutal on a car’s cooling system. The hotter the air temperature, the harder your car has to work to shed heat. Learning how to prevent car overheating in summer is crucial, especially in the sweltering heat of North Dakota and Minnesota.

• Don’t Overwork Your A/C: Your air conditioning system puts extra strain on the engine. If you are idling in traffic or driving up a long, steep hill on a scorching day, turn off the A/C or switch to just the fan for a bit. Reducing this load can give your engine a much-needed break.
• Mind the Traffic: Stop-and-go traffic is a killer for cooling systems. When you’re not moving, there is no air flowing over the radiator to cool the coolant. If possible, try to drive during less congested hours.
• Keep Your Coolant Mix Right: You need the correct ratio of water and antifreeze. Too much water lowers the boiling point, and too much antifreeze lowers the cooling efficiency. Always use the specific type of coolant recommended by your car’s manufacturer.

How to Stop a Car from Overheating on the Road

Sometimes, despite your best efforts, you might experience the signs of engine overheating. The temperature gauge starts to climb, the ‘check engine’ light flashes, or you hear a strange bubbling sound. Don’t panic! Knowing what to do when your car overheats can prevent catastrophic engine damage.

1. Turn Off the A/C and Turn on the Heater: Yes, you read that right. Turning on the interior heater and fan to the maximum setting draws hot air away from the engine block and into the cabin, acting as a secondary cooling system. It might be uncomfortable, but it’s a temporary fix that can save your engine.
2. Pull Over Safely: As soon as possible, pull over and turn off the engine. Do not try to keep driving. Find a safe spot, put the car in park, and shut it down immediately.
3. Wait and Inspect: Let the car cool down for at least 30 minutes. NEVER open the radiator cap or coolant reservoir cap when the engine is hot. The pressurized, boiling-hot fluid will spray out and cause severe burns. Once cooled, you can check the coolant level. If it’s low, add a 50/50 coolant mix or, in a pinch, water, to get to a local mechanic.
4. Call for Help: If you’ve added fluid and the temperature gauge climbs right back up, the issue is beyond a quick fix, and you need a tow. The moment you see that needle in the red, it’s time to call the professionals at a trusted mechanics shop like Matt’s Automotive Service Center.

How to Keep Your Car from Overheating Year-Round

While summer is the most obvious time for overheating, cold weather can also reveal underlying issues. A healthy cooling system is essential 365 days a year.

Addressing overheating car causes and solutions should be part of your yearly car care checklist:

• Check for Leaks: Small leaks are the number one cause of low coolant. They might be hard to spot, but can be coming from the radiator, hoses, water pump, or a faulty gasket. Catching a leak early is much cheaper than replacing a head gasket later.
• The Water Pump: This component is what keeps the coolant circulating. If you hear a whining noise coming from the front of the engine, it could be a sign of a failing water pump. This requires immediate auto repair cooling system service.
• The Fan: Your car has an electric fan or a fan clutch that kicks in to pull air across the radiator when the car is idling or moving slowly. If this fan isn’t working, your car will overheat in traffic. You can often see and hear the fan working when the engine is hot and the A/C is running.

By focusing on these points, you take an active role in keeping your car from overheating, protecting your investment no matter the season.

Stay Cool: Protect Your Engine and Drive with Confidence

Engine overheating is not a problem that fixes itself. Ignoring a climbing temperature gauge is the single most destructive thing you can do to your vehicle. It can lead to warped cylinder heads, blown head gaskets, and total engine failure—the cost of which is almost always in the thousands of dollars. Prevention is absolutely the most affordable solution.
