Winter in San Antonio may not bring heavy snow, but cooler temperatures, rain, and occasional cold snaps can still affect your vehicle’s performance and reliability. Preparing your car before winter arrives helps prevent breakdowns, improves safety, and ensures dependable driving through the colder months.
At Cornerstone Automotive, we help drivers across San Antonio, Round Rock, and Temple get their vehicles ready for seasonal changes. Use this pre-winter maintenance checklist to keep your car running strong as temperatures drop.
Test the Battery and Electrical System
Heat is tough on batteries, and many batteries fail when temperatures drop after a long Texas summer. If your battery is more than a few years old or your vehicle has been slow to start, have it tested before winter. The charging system should also be checked to ensure reliable starts during cooler mornings.
Inspect Tires and Check Tire Pressure
Temperature changes cause tire pressure to fluctuate. Underinflated tires can reduce fuel efficiency and traction, especially on wet winter roads. Make sure your tires are properly inflated and have adequate tread depth. Don’t forget to inspect the spare tire as well.
Check Brakes for Safety
Wet winter roads require dependable braking. Have your brake pads, rotors, and brake fluid inspected for wear. If you notice squealing, vibration, or reduced stopping power, address these issues before winter driving conditions increase braking demands.
Inspect and Top Off Fluids
Proper fluid levels are essential year-round. Engine oil, coolant, brake fluid, and power steering fluid should be checked and serviced as needed. Coolant should provide proper protection for occasional cold snaps, while windshield washer fluid helps maintain visibility during rainy conditions.
Test Heating and Defroster Systems
Even mild winters require a working heater and defroster for comfort and visibility. Make sure warm air flows properly and windows clear quickly during cool, damp mornings.
Inspect Wipers and Exterior Lights
Winter rain and early morning driving make clear visibility critical. Replace worn wiper blades and ensure all headlights, brake lights, and turn signals are functioning properly.
Address Small Issues Before They Get Worse
Minor issues such as worn belts, aging hoses, or small fluid leaks can worsen during temperature changes. Taking care of these problems now helps avoid unexpected repairs later.
