When the summer heat hits fully, your vehicle’s cooling system becomes one of the most critical components to ensure reliable performance. Whether you’re headed out on a family road trip or commuting through the Southeast’s hot temperatures, keeping your engine cool isn’t just good for performance, it can help you avoid costly breakdowns and emergency towing. At Doug Yates Towing & Recovery, we’ve seen firsthand how many summer vehicle issues start with cooling system failures.
In this blog, we will show you how to prepare your vehicle’s cooling system for summer heat, what to look out for, and when to call for roadside assistance. This proactive approach can save you time, money, and the headache of searching for a “tow truck near me” in the middle of a heatwave.
Your car’s cooling system is designed to prevent the engine from overheating. It circulates coolant (also called antifreeze) through the engine block and radiator to dissipate heat. In the summer months, especially here in Tennessee where temperatures often soar past 90°F, the risk of overheating increases dramatically. An overheated engine can cause:
That’s why it’s critical to inspect and maintain your cooling system before temperatures peak.
Start with the basics: check your coolant level. Your owner’s manual will show you where the coolant reservoir is located. Make sure the coolant is between the “MIN” and “MAX” marks. If it’s low, top it off with the appropriate mixture of water and antifreeze, usually a 50/50 ratio.
Also, inspect the coolant itself. If it appears rusty, dirty, or has debris floating in it, it’s time to flush the system. Old or contaminated coolant can’t do its job properly, increasing the risk of engine overheating.
The rubber hoses that carry coolant to and from your radiator can become brittle over time. Look for:
Your engine’s serpentine belt, which powers the water pump and other components, should also be checked for cracks, fraying, or signs of excessive wear. A broken belt or burst hose can instantly disable your cooling system and that’s when Doug Yates Towing & Recovery is here to help with fast, professional roadside assistance and emergency towing.
Your radiator should be free of external damage, leaks, and blockages. Dirt, bugs, and debris can collect on the radiator fins, restricting airflow. Clean the front of the radiator with a hose or gentle brush.
Also, don’t overlook the radiator cap. It’s designed to maintain pressure in the cooling system. If it’s worn out or can’t hold pressure, the system won’t function properly, and overheating becomes more likely.
The thermostat regulates the flow of coolant based on engine temperature. A malfunctioning thermostat can stay closed too long, preventing coolant from flowing to the radiator. Similarly, the water pump circulates coolant throughout the engine. If it fails, the system shuts down entirely.
If you notice unusual temperature fluctuations, coolant leaks under your vehicle, or whining noises from the engine bay, these could indicate water pump or thermostat issues. Have a trusted mechanic perform a diagnostic.
Most vehicle manufacturers recommend a coolant flush every 30,000 to 50,000 miles, or every 2–5 years. Flushing the system removes rust, scale deposits, and old coolant that no longer protects against high temperatures. This preventative maintenance is much more affordable than an engine replacement or paying for emergency towing when your vehicle overheats.
Even with proper maintenance, cooling system issues can arise, especially in extreme summer heat. Here are some red flags to watch for:
