How to Protect Your Car’s Cooling System During Warmer Months

As temperatures rise, your car’s cooling system becomes one of its most important defenses against breakdowns. A properly functioning cooling system keeps your engine at the right temperature, preventing overheating and costly damage. Unfortunately, the warmer months can push this system to its limits—especially if routine maintenance has been overlooked. Here’s how to protect your car’s cooling system and avoid getting stranded when the temperature rises.

Why Your Cooling System Matters

Your engine generates a lot of heat while running. The cooling system’s job is to regulate that heat using a combination of coolant, a water pump, radiator, thermostat, cooling fan, and hoses. When any part of this system fails, it can lead to overheating, engine damage, or even total engine failure.

In the warmer months, high outdoor temperatures, stop-and-go traffic, and increased use of air conditioning add extra stress. That’s why proactive care is so important.

Tips to Keep Your Cooling System in Top Shape

Check Coolant Levels Regularly

Coolant (or antifreeze) absorbs heat from the engine and dissipates it through the radiator. Low coolant levels can quickly lead to overheating.

Tip:

• Check your coolant level at least once a month when the engine is cold.
• If it’s low, top it off with the correct coolant mixture recommended by your vehicle’s manufacturer.

If you find yourself adding coolant frequently, it could signal a leak that needs professional attention.

Inspect for Leaks and Hose Wear

Heat can cause hoses to become brittle and crack over time. Coolant leaks are often one of the first signs of a cooling system problem.

Tip:

• Look for puddles of green, orange, or pink fluid under your car.
• Inspect hoses for cracks, bulges, or soft spots.

If you notice any issues, bring your vehicle to Mighty Auto Pro for a thorough inspection.

Keep the Radiator Clean and Clear

A clogged or dirty radiator can’t effectively dissipate heat. Dirt, bugs, and debris can accumulate on the radiator fins, especially during spring and summer driving.

Tip:

• Periodically check the front of the radiator and gently clean off any buildup with a soft brush or low-pressure water spray.

Also, make sure nothing is blocking airflow to the radiator, like aftermarket grill covers or debris.

Flush the Cooling System as Recommended

Over time, coolant breaks down and loses its effectiveness. Old coolant can also become acidic and corrode engine components.

Tip:

• Follow your vehicle manufacturer’s recommended coolant flush schedule—typically every 30,000 to 50,000 miles.
• If you’re not sure when your last flush was, our technicians can check the condition of your coolant.

Watch Your Temperature Gauge

The temperature gauge on your dashboard is a simple but essential tool. If it starts creeping into the red zone or you notice steam coming from under the hood, pull over immediately and turn off the engine to avoid serious damage.

Never attempt to open a hot radiator cap, as this can cause serious burns.
