Summer heat can be brutal—not just for you, but for your vehicle too. When temperatures rise, your engine works harder to stay cool. Without the right maintenance and precautions, that added strain can lead to overheating, engine damage, or even complete breakdowns.
At Ken’s Automotive & Transmissions, we’ve helped countless drivers protect their engines through the hottest months of the year. If you want to avoid roadside emergencies and keep your vehicle running smoothly, here’s what you need to know about keeping your engine cool when the heat is on.
Why Engine Cooling Matters in Summer
Your engine creates a lot of heat, even in cooler weather. During the summer, extreme temperatures and heavy use—like running your A/C or towing—only add to that heat load. Your vehicle’s cooling system is designed to regulate temperature, but if any part of it is underperforming or failing, your engine could quickly overheat.
Overheating isn’t just inconvenient—it can warp engine components, blow a head gasket, or cause permanent damage, leading to costly repairs. That’s why proactive care is important.
Top Ways to Keep Your Engine Cool
1. Check and Top Off Your Coolant
Coolant (or antifreeze) is your engine’s first line of defense against heat. It circulates through the engine, absorbing heat and carrying it to the radiator where it’s released.
- Make sure coolant levels are between the “min” and “max” marks on the reservoir.
- If your coolant is dirty or low, have it flushed and refilled with the proper type for your vehicle.
If you’re unsure about coolant condition, Ken’s offers full inspections and flush services to keep your system in top shape.
2. Inspect the Radiator and Hoses
A clogged or damaged radiator won’t be able to dissipate heat effectively. Similarly, cracked or leaking hoses can lead to coolant loss—and that’s a quick path to overheating.
- Look for leaks, swelling, or soft spots in hoses.
- Make sure the radiator isn’t blocked by debris like bugs or leaves.
- Keep the fins clean and straight for optimal airflow.
3. Keep an Eye on Your Temperature Gauge
Your dashboard temperature gauge is there for a reason. If you notice it climbing higher than normal—especially into the red—pull over and turn the engine off. Continuing to drive with an overheating engine can cause major damage fast.
4. Don’t Overload Your Engine
Towing a trailer, climbing steep hills, or driving in stop-and-go traffic all put extra strain on your engine. During extreme heat, give your engine a break when possible:
- Avoid idling for long periods.
- Use lower gears on inclines.
- Turn off A/C in heavy traffic if the temperature gauge is rising.
5. Get Regular Cooling System Inspections
Your vehicle’s cooling system includes multiple components that need to be in sync—radiator, thermostat, water pump, fan, and coolant. A failure in any part of that system can lead to problems.
At Ken’s, we offer cooling system inspections that include pressure tests, coolant analysis, and system performance checks. We’ll help you catch issues early, so you can drive with confidence even in triple-digit temps.
