Winter Car Checklist for Arlington Drivers

Northern Virginia winters are short on snow and long on freeze-thaw, salt and dead batteries. Here is what to check before the first hard cold, in the order it tends to bite.

Winter in Arlington rarely looks like winter in Buffalo. What we get instead is a season of swings: a mild week, an overnight freeze, a dusting that shuts down half of Langston Blvd, then road treatment that sits on the underside of your car for days. That pattern finds weak parts. A battery that was fine in October will not turn the engine over at 20°F. A tire that was a little low in September is properly low by January.

Here is the checklist we would run on our own cars, roughly in order of what strands people first. Most of it takes minutes, and the rest is easiest to knock out alongside an oil change or your state inspection.

1. Battery: test it before the cold does

The cold gets the blame, but the damage usually happens earlier. Summer heat wears a battery down, and the first hard freeze exposes it, because cold slows the chemistry inside the battery at the same moment thick oil makes the engine harder to turn. We cover the full story in why car batteries die early in Virginia.

What to do:

If your battery is around three years old or more, have it load tested now rather than waiting for a slow start.
Look at the terminals. White or green crust adds resistance and is simple to clean.
Take a slower crank as a warning. Batteries often give you a few days of notice before they quit.
If the car sits for a week or more, or only does short hops around Arlington, the alternator never gets a chance to fully recharge the battery. A longer drive each week helps.

If you need one tested or replaced, our battery, alternator and starter service checks the whole charging system. A new battery will not last long on a failing alternator.

2. Tire pressure and tread

Air contracts as it cools, and the usual rule of thumb is roughly one PSI lost for every 10°F drop. That is why the tire pressure light tends to come on during the first cold morning of the season, then go off after a few miles of driving. Our TPMS guide explains what the light is really telling you.

Set pressure cold. Check before you have driven far, and use the number on the driver's door jamb, not the maximum printed on the tire sidewall.
Check tread depth. Virginia's inspection standard rejects tires below 2/32 of an inch, but that is a legal floor, not a winter target. Tires near that depth lose their grip on wet and slushy roads well before they fail inspection.
Do not forget the spare, if your car has one. Plenty of newer cars carry a repair kit instead, and those sealant kits expire.

Our shop has free air at the pumps, so topping off costs you nothing but a stop.

3. Coolant and heater

Coolant protects your engine against freezing as well as overheating, and it does not last forever. Look at the overflow tank with the engine cold and make sure the level sits between the marks. Never open a hot radiator cap.

Pay attention to the heater, too. A heater that blows lukewarm air can mean low coolant, a stuck thermostat, or a blend door problem, and a sluggish temperature gauge in winter often points at the thermostat. Either way, you want to find out before a long drive, and our cooling and AC service covers both ends of the system.

4. Wipers, washer fluid and glass

Wipers are cheap, and they matter most in exactly the conditions when you can least afford streaks.

Replace blades that chatter, streak or have split rubber.
Run a washer fluid rated for freezing temperatures. Summer fluid can freeze in the lines and on the glass.
Never pour hot water on an icy windshield. A sudden temperature change can turn a small chip into a long crack.
Get chips looked at early. Under the 2026 State Police manual, a pit, chip or star crack larger than 1-1/2 inches above the three-inch line at the bottom of the windshield is grounds for rejection, and cold makes chips spread.

One Virginia rule worth knowing: your headlights must be on whenever your wipers are in use because of fog, rain, sleet or snow, apart from intermittent use in a light mist. Automatic headlights do not always catch this on a gray morning, so check the switch.

5. Brakes

Wet and slick roads give you less margin, so a brake problem that is merely annoying in August matters more in January. Road treatment also speeds up rust on rotors, calipers and brake lines, and a car that sits in the cold can develop a light surface rust that clears after a few stops. Rust that does not clear, or a car that pulls, grinds or pulses, needs a look. See six signs your brakes need attention, or stop by for a free brake inspection.

6. Oil and the small stuff

Modern synthetic oils flow well in cold weather, but only if they are the viscosity your manufacturer specifies and in decent condition. If your car is close to its oil change interval, do it before winter rather than after. Short trips are harder on oil than highway miles, and they describe most driving around Arlington. Our oil change guide explains how to find your real interval.

While you are there, have someone check the serpentine belt and hoses. Rubber goes brittle in the cold, and a belt that was glazing in the fall can let go in January.

7. Wash off the road treatment

Road salt and treatment chemicals are hard on the underside of a car. After a treated storm, a wash that reaches the undercarriage is cheap protection for brake lines, fuel lines and the floor pan. It matters for inspection as well: the State Police manual rejects vehicles with a floor pan rusted through.

If you drive an EV or a hybrid

Cold affects electrified cars more than most owners expect. In testing published in May 2026, AAA found that at 20°F with the cabin heated to 72°F, electric vehicles lost about 39% of their calculated driving range compared with 75°F, and hybrids lost about 22.8% of their fuel economy.

AAA's advice comes down to a few habits:

Warm the cabin while the car is still plugged in.
Use heated seats and the heated steering wheel instead of full cabin heat.
Keep tires properly inflated.
Plan for shorter range and extra charging stops on winter road trips.

Every EV and hybrid still has a 12-volt battery that runs the computers and door locks, and that battery can fail the same way it does on any other car. We cover the rest in our hybrid and EV maintenance guide.

What to keep in the car

Phone charger and a small flashlight
Ice scraper and snow brush
Gloves, a warm layer and a blanket
Jumper cables or a charged jump pack
Water and a snack, because I-66 can turn a 20-minute drive into a very long one
A small bag of sand or cat litter for traction

Keep the gas tank from running near empty when a storm is forecast. It gives you a reserve if you get stuck in traffic with the heater running.

The short version

Battery, tire pressure, wipers. If you only do three things before the first freeze, do those. If you would like someone to go through the list for you, call TAB Motors Arlington at (703) 243-3080 or stop by 4035 Old Dominion Dr. We are open Monday to Friday 7 to 6 and Saturday 7 to 3.
