Keep Your Subaru Running Cool in Washington Township, OH

Hot summers in Washington Township can do more than just make you sweat — they can push your Subaru to its limits. From overworked A/C systems to low coolant levels and high tire pressure, the heat can affect your comfort, fuel efficiency, and safety.

Here’s how to prepare your Subaru for the rising temperatures and long summer drives across Montgomery County and beyond.

Why Summer Heat Demands Extra Car Care

Summers in Southwest Ohio can hit the high 80s and 90s, with humidity to match. That heat isn't just uncomfortable — it puts extra strain on your vehicle’s core systems. Whether you're commuting from Miamisburg or taking a weekend road trip, extreme temps can lead to:

• A/C systems underperforming or blowing warm air
• Engines overheating due to low or degraded coolant
• Tires overinflating from heat buildup, risking blowouts

A/C System Tips: Stay Cool Inside Your Subaru

If your air conditioner isn’t blowing cold air like it used to, it might be time for a recharge or inspection. A struggling A/C can be caused by refrigerant leaks, a worn compressor, or clogged filters.

🧊 Stay cool with these tips:

• Replace your cabin air filter every 15,000–20,000 miles for cleaner airflow
• Recharge refrigerant if airflow is weak or warm
• Listen for odd noises from the A/C, it could signal a failing compressor
• Run the A/C regularly even in mild weather to keep seals lubricated

“Most customers don’t realize that skipping cabin air filter replacements can make their A/C work harder — especially in humid Dayton summers,” says Tony Harper, Subaru Master Technician at Subaru of Dayton.

Coolant System Care: Prevent Overheating

Your engine's coolant keeps temperatures stable. But in the summer heat, low coolant or an old mix can spell trouble — even a breakdown.

Here’s what to do:

• Check coolant levels monthly (only when the engine is cool)
• Ensure the coolant is clear and at the proper mix of antifreeze and water
• Replace coolant every 60,000–100,000 miles, depending on your Subaru model
• Watch for sweet smells or steam — signs of leaks or overheating

💧 Pro tip: Have your radiator and hoses inspected annually. Rubber parts are prone to cracking in high heat.

Tire Pressure & Tread: Safety Starts on the Road

Summer heat causes air inside your tires to expand. That means higher tire pressure, which can lead to uneven wear or, worse, a blowout at highway speeds.

🚗 Key tire tips for hot weather:

• Check tire pressure weekly — especially before long drives
• Follow Subaru’s recommended PSI (found in your driver’s door jamb)
• Inspect tread depth — minimum safe depth is 2/32"
• Rotate tires every 5,000–6,000 miles for even wear

Don’t Wait for a Breakdown

Summer road trips are supposed to be fun, not interrupted by warning lights or roadside calls. That’s why regular maintenance is crucial, especially on the hottest months, is essential for keeping your Subaru running at its best.

“In Washington Township, we see a big spike in overheating issues and tire blowouts in late July,” says Tony. “A quick summer checkup can save you a lot of stress.”
