Preventive Maintenance for Phoenix Heat

These simple maintenance tasks can prevent breakdowns in extreme temperatures:

✓
Battery Testing: Test every 6 months. Heat kills batteries faster than cold.
✓
Coolant Flush: Every 2 years or 30,000 miles. Critical for Phoenix driving.
✓
Tire Pressure: Check weekly in summer. Add 2-4 PSI for heat expansion.
✓
Oil Changes: Every 3,000 miles in extreme heat. Use proper viscosity.
✓
AC Service: Annual inspection before May. Don’t wait until it fails.
✓
Belt Inspection: Heat degrades rubber. Check for cracks monthly.

When to Call a Professional Immediately

  • You’re stranded on a highway or unsafe location
  • Temperature is above 105°F and you’re outside
  • You smell burning, see smoke, or hear grinding

Frequently Asked DIY Questions

How often should I check my battery in Phoenix? ▼
Check your battery every 3 months in Phoenix. The extreme heat shortens battery life to 2-3 years compared to the national average of 3-5 years. Look for corrosion on terminals, swelling of the battery case, or slow engine cranking. Our $29.99 battery special includes free testing and installation.
Can I add water instead of coolant in an emergency? ▼
Yes, in an emergency you can add water to get to safety, but it’s temporary. Water alone will boil at 212°F while Phoenix engines can reach 250°F+. Proper 50/50 coolant mix raises the boiling point to about 265°F. After adding water, get proper coolant service within 24 hours to prevent damage.
Why do tires blow out more in Phoenix summers? ▼
Phoenix road surfaces can reach 160°F+, causing tire pressure to increase by 4-6 PSI. Combined with underinflation, this heat stress causes sidewall failure. Check tire pressure early morning when cool, and never reduce pressure on hot tires. Rotate tires every 5,000 miles for even wear.
Is it safe to work on my car in 115° weather? ▼
NO – it’s extremely dangerous. At 115°F, you risk heat stroke within 10-15 minutes of physical activity. Metal parts can cause severe burns, and you may become disoriented. Call our 24/7 service at (602) 367-2975. We’re equipped and trained for extreme heat conditions. Your safety is worth more than any repair cost.
What’s the most common Phoenix car problem? ▼
Battery failure is #1, followed by AC problems and cooling system failures. The extreme heat accelerates chemical reactions in batteries, evaporates coolant faster, and stresses AC systems running constantly. We see 3x more battery replacements June-September than other months. Keep our number handy: (602) 367-2975.
