As summer temperatures intensify in the Kingdom, vehicles are exposed to harsh conditions that can lead to sudden breakdowns if necessary precautions are not taken. Driving under the scorching sun not only exhausts the driver but also tests the durability of every part of the car, especially the engine, tires, and battery, which are most affected by high temperatures.

Therefore, we offer you this practical guide that highlights the best practices to protect your car during the summer, ensuring reliable performance and avoiding costly breakdowns. Follow these tips for a safe and comfortable journey.

Protecting the Engine: Cooling System and Oil

The engine is the heart of the car and suffers most from high heat. First, ensure the cooling system is intact: check the coolant (radiator) level and ensure no leaks, and inspect hoses for cracks or bulges. Use a dedicated coolant suitable for high temperatures and flush the radiator periodically according to the manufacturer's recommendations.

As for engine oil, choose oil with appropriate viscosity for summer and ensure it is changed according to the recommended schedule. High heat causes oil to oxidize faster, losing its lubricating properties. It is also advisable to check the cooling fans and electric fan to ensure they work efficiently, especially when stopping in traffic.

Tires: Air Pressure and Safety

Tires are the only contact point between the car and the road, and they face increased pressure in summer due to heat and asphalt friction. Check tire pressure weekly and when the tires are cold (before driving or after the car has been parked for an hour). Heat raises internal air pressure, so ensure it does not exceed the manufacturer's recommended maximum.

Also check tread depth and ensure there are no cracks or bulges. It is advisable to replace tires showing signs of uneven wear, as this increases the risk of blowouts at high speeds. Do not forget to check the spare tire as well, as you may need it at any moment.

Battery: Heat Is Its Worst Enemy

Contrary to popular belief, extreme heat damages the battery more than cold. It accelerates internal chemical reactions and increases the rate of corrosion, reducing its lifespan. Therefore, ensure the battery terminals are clean and free of corrosion (oxidation) using a wire brush and a sodium bicarbonate solution.

Check the battery fluid level if it is a maintenance type, and add distilled water when necessary. It is preferable to have the battery voltage checked by a specialized technician before summer, especially if it is over three years old. Also, be careful not to leave lights or electrical devices on with the engine off, as this drains the battery and may prevent the engine from starting the next day.

Additional Tips to Reduce Cabin Heat

Use sunshades (reflectors) on the front and rear windows to reduce cabin temperature rise, which lessens the load on the air conditioner and preserves the battery. If your car is parked under the sun, open the windows for a minute before turning on the AC to expel hot air.

Ensure the air conditioning system is checked and maintained regularly, as it bears an additional operating load in summer. Clean the cabin air filter to ensure cool and clean airflow. It is also advisable to avoid driving during peak heat hours if possible, or plan long trips for early morning or evening.

In the end, a little care and regular inspection before and during the summer can save you the trouble of breakdowns and high repair costs, and ensure a safe arrival. Remember that your car needs special attention in the harsh climatic conditions the Kingdom experiences. So be sure to follow these tips to enjoy a comfortable and safe drive throughout the heat season.
