Driving in Los Angeles Heat: How Extreme Temperatures Affect Your Vehicle

The scorching Los Angeles summer sun doesn't just affect people—it can take a serious toll on your vehicle as well. As temperatures in Woodland Hills, Calabasas, and surrounding areas regularly climb into the 90s and beyond, understanding how heat affects your car can help you avoid unexpected breakdowns and costly repairs. At Collision Buddy, we've seen firsthand how extreme temperatures can accelerate wear and damage on vehicles, especially during extended heat waves.

How Heat Impacts Your Vehicle's Critical Systems

Battery Stress and Failure

Hot weather is actually more damaging to car batteries than cold. When temperatures rise above 90°F, the risk of battery failure increases dramatically. The intense heat accelerates internal corrosion and evaporates essential fluids within the battery, reducing its lifespan.

Warning Signs:

• Slow engine cranking during startup

• Dimming headlights when idling

• Electrical components functioning inconsistently

• Battery warning light illuminated on dashboard

Cooling System Challenges

Your engine's cooling system works overtime during hot weather, making it more susceptible to failure precisely when you need it most.

Heat-Related Cooling Issues We Often See:

• Radiator leaks developing from increased pressure

• Coolant breaking down faster than normal

• Cooling fans failing from constant operation

• Water pump wear accelerating under heat stress

Tire Pressure and Wear Concerns

Did you know that tire pressure increases approximately 1 PSI for every 10°F temperature increase? Southern California's dramatic temperature swings between morning and afternoon can wreak havoc on your tires.

Over-inflated tires due to heat expansion wear unevenly and are more susceptible to blowouts on hot pavement. Meanwhile, under-inflated tires flex more, generating additional heat and increasing rolling resistance, which reduces fuel efficiency and accelerates wear.

Interior Component Deterioration

The greenhouse effect inside a parked car can cause temperatures to reach 140°F or higher, even on an 80°F day. This extreme heat can:

• Cause dashboard cracking and fading

• Deteriorate seat materials faster

• Damage electronics and displays

• Weaken adhesives holding interior components together

Preventative Maintenance Tips for SoCal Drivers

Living in Woodland Hills, Tarzana, or Calabasas means your vehicle needs special attention during the hottest months. Our certified technicians recommend these preventative measures:

1. Battery Care in High Heat

• Have your battery tested before summer begins

• Keep battery terminals clean and corrosion-free

• Consider upgrading to a battery specifically designed for extreme temperatures if you're due for replacement

• Park in shade whenever possible to reduce under-hood temperatures

2. Cooling System Maintenance

• Flush and replace coolant according to manufacturer recommendations

• Inspect hoses and belts for cracks before summer heat arrives

• Ensure cooling fans are operating properly

• Consider a cooling system pressure test to identify potential weaknesses

3. Tire Maintenance

• Check tire pressure in the morning when temperatures are cooler for accurate readings

• Inspect tires regularly for signs of uneven wear or damage

• Rotate tires according to schedule to ensure even wear patterns

• Consider heat-resistant tire compounds if you do extensive summer driving

4. Interior Protection

• Use windshield sunshades when parking outdoors

• Apply UV protectant to dashboard and interior surfaces

• Consider window tinting that meets California regulations (remember that front side windows must allow more than 70% of light in)

• Use seat covers to protect upholstery from UV damage and excessive heat

When to Seek Professional Help

While preventative maintenance goes a long way, sometimes professional intervention is necessary. Consider bringing your vehicle to our Woodland Hills auto repair facility if you notice:

• Temperature gauge reading higher than normal

• Sweet smell (indicating coolant leaks) or burning odors

• Visible leaks under the vehicle after parking

• Warning lights on your dashboard

• Unusual noises from the engine bay, especially the cooling fan

• Air conditioning performance declining

Beyond Prevention: Emergency Preparedness

Even with excellent maintenance, emergencies can happen. We recommend all Southern California drivers keep these items in their vehicles, especially during summer heat waves:

• Extra coolant (properly diluted)

• Bottled water (for both you and potentially your radiator in an emergency)

• Basic tools including screwdrivers, pliers, and wrenches

• Jumper cables

• Emergency contact information including roadside assistance

• Sunscreen and hat (if you need to wait outside your vehicle)
