Here’s How Summer Weather Can Damage Your Car

Summer weather, believe it or not, can actually damage our cars in a number of ways. Here’s how, and what you can do about it…


Car batteries don’t like extreme temperatures, hot or cold. During the summer, heat can wreak havoc on the chemical processes taking place in the battery; making it harder for it to retain charge. If you factor in the (likely) heavy use of air conditioning, it’ll come under increased pressure, too. Older batteries are, naturally, more susceptible to failing than newer ones. When the summer months approach, try to get your car’s battery checked and, if necessary, replaced.


Oil will, when exposed to heat, thin somewhat. This means it may offer less protection to your car’s parts and components. This can lead to an increased level of friction, and therefore more wear and tear for your vehicle’s engine. The best way to avoid any problems is to top up your car’s oil level and with a high-quality product before things start to get too warm.


Coolant, as the name implies, gets your car’s engine and other parts at a reasonable temperature. During the summer months, it has to work harder to keep out excessive heat. Coolant generally has to work harder when you’re travelling at lower speeds, as less air is flowing through the fan at the front of your vehicle. As with oil, make sure that you’ve got plenty of coolant at the start of summer.


Higher temperatures can cause the air inside a car’s tyres to expand, which can lead to over-inflation or even bulging. This increases the chances of punctures and blowouts. Neither is something you want to experience whilst cruising down a motorway. To avoid this scenario, regularly check your tyres air pressures and inspect them for any signs of damage.

Air Conditioning

You’ll likely be using your car’s air conditioning on a regular basis during the warmer months of this year. If you’ve neglected its maintenance, the extra strain can lead to it failing when it faces a lot of strain. Should it fail, you’ll face a hefty repair bill. In advance of the heat, get your car’s ac system checked. When driving at lower speeds, simply lower your windows.


Most modern vehicles possess advanced paintwork that doesn’t react when exposed to intense sunlight. However, some older models may see their paintwork deteriorate when left out in the sun. If you’re driving an old vehicle, try to park in the shade or invest in a car cover. Some cleaning products, such as car wax, can also offer an extra layer of protection, too.
