With the onset of summer, rising temperatures can have a significant impact on your car and its maintenance. It’s important to understand how heat can affect the mechanics of your vehicle and what steps you can take to mitigate these effects.
Let’s explore the potential effects of heat on your car and discuss effective ways to combat them, ensuring your vehicle remains in optimal condition during the summer season.
Tire changes
During summer or periods of high temperatures, it’s crucial to pay attention to the condition of your car’s tires. The extreme heat experienced on hot days can lead to premature wear and potential safety hazards.
To ensure road safety and minimize the risk of accidents, it’s important to regularly check the tread depth of your tires. While the legal limit is 1.6 millimeters, it’s advisable to maintain a minimum tread depth of at least 2 millimeters. This not only ensures compliance with safety standards but also provides better grip on the road.
Additionally, it’s essential to monitor the tire pressure. High temperatures can cause an increase in tire pressure, but it’s equally important not to drive with underinflated tires, as it significantly increases the risk of a blowout by 60%. Refer to the manufacturer’s recommended tire pressure and ensure it is maintained accordingly. In cases of extreme heat, it is acceptable to have a slight excess of 0.3 bar in tire pressure.
By regularly checking the tread depth and maintaining proper tire pressure, you can effectively combat the adverse effects of heat on your car’s tires, ensuring optimal performance and road safety.
Loss of power and increased consumption
One noticeable effect of high temperatures on our vehicles is a loss of power, which is often attributed to running the air conditioning (which can indeed reduce power). However, the actual reason behind this power loss is related to the availability of air for combustion in the engine. As the temperature rises, the air contains less oxygen, making it more difficult for the fuel to burn efficiently, resulting in decreased engine performance.
This effect is particularly evident in turbocharged or supercharged engines, especially those without an intercooler, as they require more air for optimal function. Therefore, the lack of oxygen affects them even more, leading to a loss of up to 15 horsepower. Each additional degree in your car’s temperature can reduce its on-road performance, potentially resulting in power losses of up to 15%. If the air filter is also dirty, this situation worsens.
In addition to the loss of engine power, these conditions also contribute to increased fuel consumption. The less easily combustible mixture caused by heat leads to a higher fuel consumption rate, resulting in an average increase of one liter per 100 kilometers.
To combat these issues, it’s important to check the air conditioning and cooling system of your vehicle. Any leaks in the system can cause the engine to overheat, potentially leading to a breakdown. Common areas for leaks include the cap, hoses, or clamps, which are relatively easy to fix. The key is to prevent the engine from running without sufficient coolant, as this can result in overheating and potential damage. Regular maintenance and monitoring of the cooling system are essential to ensure optimal performance and prevent costly repairs.
Break system
To prevent any unpleasant surprises, it’s advisable to inspect the condition of your brakes. The braking system is regularly exposed to high friction, generating heat. During summer, the temperature rises significantly, further increasing the heat transferred to the brake discs. In extreme cases, this excessive heat can cause the brake discs to deform, compromising their effectiveness. Additionally, the high temperature can lead to faster evaporation of the brake fluid.
To mitigate these risks, it’s recommended to employ certain driving techniques. Utilizing low gears when descending long slopes on roads and highways helps to slow down the vehicle without relying heavily on the brakes. This approach minimizes the strain on the braking system and reduces the risk of overheating. By practicing this driving technique, you can help maintain your car’s brakes and ensure their optimal performance during the summer months.
