There’s nothing quite like a Colorado summer. From winding mountain passes to red rock canyons and alpine lakes, the Centennial State is built for adventure. But before you hit the road for that weekend getaway or cross-state trek, your vehicle needs to be prepped for the high demands of Colorado’s terrain and weather.

Here’s how to get your car road-trip ready—and avoid getting stranded somewhere between civilization and cell service.

🚙 Why Summer Prep Matters in Colorado

Colorado’s landscape is as beautiful as it is unpredictable. You can go from 90°F on the plains to freezing rain at 10,000 feet, all in one day. Steep inclines, long descents, and high elevations push your vehicle harder than normal. That’s why a little maintenance now can save you a breakdown (or brake failure) later.

🔧 The Summer Road Trip Readiness Checklist

✅ 1. 

Tires: Your First Line of Defense

• Check tread depth—you’ll want at least 4/32” for mountain driving.
• Inspect for sidewall cracks or bulges.
• Adjust tire pressure for elevation changes. Higher altitudes can increase PSI.
• Don’t forget the spare—make sure it’s aired up and your jack is in good shape.

Pro Tip: Tire pressure changes roughly 1 PSI for every 1,000 feet of elevation gain or loss.

✅ 2. 

Brakes: Don’t Gamble on Downhill Grades

Driving through Colorado’s mountains means lots of downhill braking. If your brakes are worn, hot pads can fade fast.

• Have your brake pads and rotors inspected.
• Watch for vibrations, grinding, or soft pedals.
• Ask about brake fluid—it’s often overlooked but crucial for performance.

✅ 3. 

Cooling System: Beat the Heat

Your engine works harder in the summer, especially climbing mountain roads.

• Make sure your coolant level and mixture are correct.
• Look for leaks or brittle hoses.
• A radiator flush may be wise if it’s been more than 2 years.

✅ 4. 

A/C and Cabin Air Filter: Comfort Counts

Nothing ruins a road trip like stale air and a weak A/C on a 90° day.

• Test your air conditioning before departure.
• Change the cabin air filter if airflow is low or smells musty.
• If it’s still underperforming, your system may need a refrigerant recharge.

✅ 5. 

Oil & Fluids: Lifeblood of Your Engine

• Check oil level and age—consider a fresh oil change if it’s close to due.
• Top off transmission, brake, and washer fluids.
• Use washer fluid with bug remover—those summer bugs come fast and thick on Colorado highways.

✅ 6. 

Battery: Heat Kills Weak Batteries

Summer heat stresses batteries as much as winter cold.

• Check the battery age (3+ years? Get it tested).
• Look for corrosion on terminals.
• Make sure it’s secured—rough mountain roads can jostle loose connections.

🚨 Pack a Colorado-Specific Emergency Kit

• Water + snacks – hydration is crucial at altitude.
• Blanket or jacket – mountain temps can drop fast.
• First aid kit, flashlight, and jumper cables
• Portable tire inflator or patch kit
• Paper map – cell signal can vanish in remote areas.

🧰 Consider a Pre-Trip Vehicle Inspection

If DIY isn’t your thing—or you just want peace of mind—most reputable auto shops in Colorado offer pre-trip inspections. These typically include:

• Tire and brake checks
• Fluid levels and leaks
• Battery and A/C tests
• Suspension and steering review

It’s a small investment that could save you a costly tow on a remote mountain pass.

🗺️ Final Thoughts: Drive Smarter, Travel Farther

Colorado is made for road trips, but the adventure starts with a vehicle that’s ready to meet the challenge. A quick checkup now means less worry later—and more time enjoying the open road.

So before you head for the hills, make sure your ride is up to the task. A well-prepped car makes every Colorado mile more enjoyable (and a lot less stressful).
