Preparing Your Car for Summer in the Inland Empire

The Inland Empire Heat Problem

Living in Hemet and the surrounding Inland Empire means your vehicle endures some of the most extreme heat conditions in the country. Temperatures above 100 degrees are the norm from June through September, with frequent spikes above 110. This heat affects every system in your car -- from the paint on the outside to the fluids on the inside.

The good news is that a little preparation goes a long way. Here is what matters most.

Protect Your Paint

UV radiation is the number one enemy of automotive paint. The clear coat that protects your car's color breaks down under intense UV exposure, leading to oxidation, fading, and eventually peeling. In the Inland Empire, this process happens faster than almost anywhere else in the country.

Steps to protect your paint:

• Wash regularly -- Dust, bird droppings, and tree sap become more damaging in heat. Wash your car at least every two weeks in summer.
• Wax or seal -- Apply a quality wax or paint sealant every 2-3 months. This adds a sacrificial layer of UV protection over the clear coat.
• Park in shade when possible -- A garage, carport, or even a tree shadow makes a measurable difference in paint preservation.
• Consider ceramic coating -- A professional ceramic coating provides years of UV protection and makes the car easier to clean.

If your paint is already showing signs of oxidation or clear coat failure, address it before summer makes it worse. A quality paint correction or spot refinishing now is much cheaper than a full repaint later. At Drive Auto Body, we offer paint evaluation and refinishing services that can restore faded panels before the damage becomes irreversible.

Check Your Cooling System

Your engine cooling system works hardest in summer, and a failure at the wrong time can turn a 110-degree day into a roadside emergency. Before the heat arrives:

• Check coolant level and condition -- Coolant should be at the proper level and the correct color for your vehicle's system. Rust-colored or cloudy coolant needs to be flushed and replaced.
• Inspect hoses and belts -- Rubber deteriorates faster in extreme heat. Look for cracks, soft spots, or swelling in coolant hoses. Check the serpentine belt for cracks or glazing.
• Test the radiator cap -- A weak radiator cap cannot maintain proper pressure, which lowers the coolant's boiling point.
• Verify the fans work -- Electric cooling fans should activate when the engine reaches operating temperature. If they do not, the engine will overheat in traffic.

Tire Safety in Heat

Tire blowouts spike during summer, and the Inland Empire's scorching asphalt makes this worse. Hot pavement increases tire temperature, and if your tires are already underinflated or worn, the risk of a blowout increases significantly.

• Check pressure when tires are cold -- Heat causes air to expand, so check pressure in the morning before driving. Follow the door placard pressure, not the number on the tire sidewall.
• Inspect tread depth -- Worn tires have less rubber to insulate from hot pavement. If tread is below 4/32", consider replacement before summer.
• Look for damage -- Bulges, cracks, or objects embedded in the tire are more likely to cause failure in extreme heat.

Interior Protection

Interior temperatures in a parked car in the Inland Empire can exceed 170 degrees. This damages dashboards, cracks leather, and degrades electronics. A windshield sunshade, window tinting (within California legal limits), and regular interior conditioning help prevent heat damage.

AC System Check

Your air conditioning system is not a luxury in the Inland Empire -- it is a safety feature. Driving in 110-degree heat without functioning AC is dangerous. If your AC is blowing warm or not as cold as it used to be, have it inspected before summer hits. Low refrigerant, a failing compressor, or a clogged condenser are common issues that are easier to address before the system is under maximum stress.

Post-Accident Summer Repairs

If your vehicle has been in an accident, summer heat can accelerate problems from incomplete repairs. Bare metal exposed from chipped paint will rust faster in heat cycles. Poor-quality clear coat breaks down faster under UV. Damaged seals allow water from monsoon storms to enter the cabin.

At Drive Auto Body, we see the consequences of deferred repairs every summer. If you have been putting off collision repair, address it before the heat makes the damage worse. Call us at (951) 268-3006 or visit our shop at 33975 State Highway 74 in Hemet for a free estimate.
