Ten effective ways to protect your car from sun damage

Prolonged exposure to the sun can have devastating effects on your vehicle. When outdoor temperatures rise, the car interior can reach up to 63°C, while the exterior surface can approach 93°C. These extreme temperatures can damage the paint, interior, and mechanical components of the vehicle.

The path to effective car protection starts with understanding how heat affects the vehicle’s different systems and implementing simple yet effective preventive measures.

Regular Fluid Level Checks

High temperatures accelerate the consumption of fluids in the car’s systems. Coolant plays a crucial role in maintaining the engine’s optimal temperature, while gear oil ensures proper transmission operation.

What to check:

• Coolant level and color
• Quantity and viscosity of engine oil
• Level of brake fluid and power steering fluid
• Condition of windshield washer fluid

Lower levels of these fluids, combined with high temperatures, significantly increase the risk of costly engine or transmission damage.

Battery Testing in Hot Weather

Extreme heat places additional stress on the car battery, especially as the air conditioning system runs at maximum capacity. The battery can suffer permanent damage if it is constantly exposed to high temperatures.

• Open-circuit voltage test (12.6V for a healthy battery)
• Check terminals for corrosion
• Inspect charging system (alternator)
• Clean and protect the terminals

A faulty battery in hot days can leave the vehicle immobilized at the most inopportune moments.

Maintaining Air Filters in Optimal Condition

Summer brings more dust, pollen, and particles in suspension, which can clog the engine’s air filter. A clogged filter reduces engine performance and can affect the mass air flow sensor (MAF), the component responsible for regulating the air-fuel mixture.

Effects of a blocked filter:

• Increased fuel consumption
• Reduced engine power
• Higher pollutant emissions
• Premature wear of engine components

Regular replacement of the air filter is a small investment with major benefits for the health of the engine.

Using Reflective Sun Panels

Although it may seem inconvenient, using reflective sun panels for the windshield and rear window can significantly reduce the interior temperature by up to 15-20°C. This not only makes the car more comfortable upon return, but also reduces the load on the air conditioning system.

Additional benefits:

• Protecting upholstery from fading
• Preventing dashboard cracking
• Maintaining the vehicle’s resale value
• Reducing fuel consumption (AC works less)

Tire Pressure Monitoring

Correct tire pressure becomes critical in hot season. Heat causes air inside the tires to expand, increasing pressure, while insufficient pressure can lead to overheating and even tire blowout.

Important rules:

• Check pressure early in the morning when tires are cold
• Follow manufacturer recommended values
• Check for uneven tread wear
• Check the tire production date (replace after 6-7 years)

A tire blowout at high speed can have severe consequences for road safety.

Smart Parking Strategies

Choosing a parking spot can make the difference between a comfortable car and a hot one. Natural shade (trees) or artificial shade (buildings, gazebos) can reduce interior temperature by up to 20°C compared to parking in direct sun.

Parking tips:

• Orient the windshield toward the east in the morning to avoid the sun in the afternoon
• Use underground parking when available
• Avoid asphalt surfaces that radiate heat
• Leave the windows slightly ajar for ventilation (safely)

Interior Maintenance

Dust and heat can create a film on interior surfaces that is hard to remove. Dust buildup can scratch plastic materials when cleaning.

Recommended cleaning schedule:

• Weekly interior vacuuming
• Wipe dust with automotive-specific products
• Protect materials with UV sprays
• Avoid harsh household detergents

Interior materials protected properly maintain their original look and feel longer.

Regular Washing and Drying

Exposed paint to sun and dust can develop permanent defects if not properly maintained. Dust and insect residues can bake onto the paint surface at high temperatures.

Correct washing technique:

• Wash the car in the early morning or evening, not in full sun
• Use neutral pH wash products
• Dry with microfiber cloths to avoid scratching
• Rinse the cloth frequently to remove abrasive particles

Neglected paint can develop permanent stains and a roughness that will require professional sanding.

Applying Protective Wax

Wax creates a protective barrier between the paint and the elements. It not only provides a glossy finish but also UV and hydrophobic protection.

Types of protection recommended:

• Natural carnauba wax (durability 2-3 months)
• Synthetic sealants (durability 6-8 months)
• Ceramic coatings (durability 2-5 years)
• Monthly maintenance sprays

A proper wax application can extend the life of the paint by years and maintain the vehicle’s value.

Investment in Paint Protection Film

Paint Protection Film, or PPF, represents the ultimate investment in protecting the vehicle’s paint. This clear film offers superior protection against UV rays, scratches, and stone impacts.

Zones for application:

• Hood and front bumper
• Side mirrors
• Door sills
• Headlights and taillights
• High-risk impact areas

Although the initial investment is substantial, the protection film can keep the original appearance of the paint for 7-10 years.

Long-Term Benefits

Implementing these preventive measures not only protects the vehicle from immediate damage but also contributes to:

• Maintaining resale value - A well-maintained vehicle retains a much higher value
• Lower repair costs - Prevention always costs less than repair
• Increased comfort - A protected cabin offers a more pleasant driving experience
• Improved safety - Systems in optimal condition respond better in critical situations

Protecting the car from the sun’s effects is an investment in the longevity and performance of the vehicle. By consistently applying these simple measures, you will be able to enjoy your car in optimal conditions, regardless of extreme weather.
