Summer weather might feel easier on your car than winter, but extreme heat can actually cause more damage. Why is heat harder on your car than cold? While cold weather slows things down, heat wears important parts out faster and puts extra stress on your vehicle. If you are planning road trips, car shows, or just more driving this summer, now is the time to make sure your car is ready.
Here are a few of the biggest ways heat affects your vehicle and what you can do to avoid problems.
Your Cooling System Works Overtime
Your engine generates a massive amount of internal heat just to keep the car moving. When you add scorching summer temperatures into the mix, your vehicle relies entirely on its cooling system to prevent a catastrophic engine failure.
The cooling system pushes coolant through the engine block to absorb excess heat. It then cycles that hot fluid through the radiator to cool it down before repeating the process. During the summer, the outside air blowing across the radiator is already hot, making this cooling process much less efficient.
If your coolant levels drop, or if the fluid becomes old and contaminated, the engine can quickly overheat. A failing water pump or a cracked radiator hose will also stop this vital cycle. Checking your coolant levels and inspecting the radiator for leaks are critical steps before the hottest months arrive.
The Surprising Truth About Car Batteries
Most people think winter kills car batteries, but high temperatures are the ultimate enemy of battery life. Heat causes the chemical liquids inside your battery to evaporate. Once those fluid levels drop, the internal lead plates become exposed and quickly corrode. This internal damage permanently ruins the battery’s ability to hold a full charge.
That damage often shows up months later when colder weather hits, but it starts during the summer. Having your battery tested before it fails is a simple way to avoid getting stranded.
Your AC Needs Attention Too
Your AC system works incredibly hard to pull hot air out of the cabin and replace it with cool, conditioned air. Over time, the refrigerant gas that makes this process possible can slowly leak out through tiny gaps in hoses and seals. When the refrigerant level drops, the system blows warm air and forces the AC compressor to work much harder than necessary. This extra strain can cause the compressor to fail entirely, leading to a very expensive repair.
If you notice weird smells, hear clicking noises from the dashboard, or feel warm air coming from the vents, your system needs attention. A professional inspection ensures your AC has the right amount of refrigerant and that all components are functioning perfectly.
Simple Summer Maintenance Checklist
A little preventative maintenance goes a long way during the hottest months of the year.
Here are a few easy things to check:
- Coolant levels
- Radiator and hoses for leaks or cracks
• Battery health and terminal corrosion
• AC performance
• Engine oil, brake fluid, and transmission fluid levels
