Fall is a transition season — cooler mornings, wet leaves on the road, shorter days, and the occasional surprise frost. It’s also the perfect time to get your car ready before winter weather sets in. Some maintenance tasks are simple enough to do yourself, while others are best left to the experts at Chantilly Service Center.
DIY Fall Car Checks
1. Check Tire Pressure and Tread
Why: Cold air makes tire pressure drop — for every 10°F drop in temperature, you lose about 1 PSI.
How: Use a tire gauge to check each tire. Compare with the sticker on your driver’s door jamb (not the tire’s sidewall).
Tread Tip: Use the penny test — insert a penny into the tread with Lincoln’s head upside down. If you can see the top of his head, it’s time for new tires.
2. Test All Exterior Lights
Why: Fall means shorter days, and good lighting is key for safety.
How: Turn on headlights, brake lights, turn signals, and hazards. Ask someone to stand outside to check them while you test.
3. Replace Wiper Blades
Why: Leaves, drizzle, and early frost make visibility a challenge.
How: Most wipers are easy to swap — just match your vehicle’s size and follow the instructions on the package.
4. Top Off Windshield Washer Fluid
Why: Road grime and falling leaves can smear your windshield.
How: Pop the hood, look for the washer fluid reservoir, and fill with winter-grade fluid to prevent freezing.
5. Clean Leaves and Debris from the Cowling
Why: The cowling — the space between your hood and windshield — can trap leaves and debris in fall. If drains here get clogged, water can leak into your cabin or damage components.
How: Pop your hood, gently remove leaves and debris by hand, and use a soft brush or vacuum for stubborn bits. Check that water drain channels are clear.
Fall Maintenance Best Left to the Pros
1. Battery Testing & Replacement
Why: Batteries lose power as temperatures drop, and a weak one can leave you stranded.
At the Shop: We use professional testers to check your battery’s performance under load — something you can’t do accurately at home.
2. Brake Inspection
Why: Wet leaves can be as slippery as ice, and you need full stopping power.
At the Shop: We measure brake pad thickness, check rotors, and inspect brake fluid.
3. Cooling System & Antifreeze Check
Why: Your cooling system also prevents freezing in the winter.
At the Shop: We test antifreeze protection levels, inspect hoses, and flush the system if needed.
4. Heating & Defrost System Service
Why: You don’t want to find out your defroster doesn’t work on the first frosty morning.
At the Shop: We check blower motors, heater core flow, and cabin filters.
5. Tire Rotation & Alignment
Why: Prevent uneven wear before winter tires go on.
At the Shop: We rotate your tires for even wear and check alignment so your car tracks straight.
