Seasonal checklist

Winter car care checklist for Lowell, MA drivers

New England winters are hard on a car — cold starts, road salt, and sudden temperature swings all add up. Here's what's worth checking before the first real cold snap, not after.

1. Battery

Cold weather is the single biggest stress test a battery faces all year — it reduces a battery's cranking power right when the engine needs more of it to start. A battery that's been "fine" all summer can fail the first genuinely cold morning. If yours is more than a few years old, it's worth having it tested before winter, not during it.

2. Tires

Tread depth matters even more on cold, wet or snow-covered roads — a tire that was fine in July can be marginal in January. Check tread depth, and don't ignore a slow leak: cold weather makes tire pressure drop further, which can turn a tire pressure light into a flat.

3. Brakes

Road salt is corrosive, and it finds its way onto brake lines, calipers and rotors all winter long. If your brakes were due for a look, going into winter — rather than waiting until spring — means you're not relying on worn components when the roads are at their worst. See our brake repair guide for the signs to watch for.

4. Coolant / antifreeze

Despite the name, your coolant system matters just as much in winter as summer — it's what keeps your engine from freezing in extreme cold, not just from overheating. A coolant check and top-off (or flush, if it's overdue) is a cheap step that prevents a very expensive problem.

5. Wiper blades and washer fluid

Summer-worn wiper blades struggle with snow and ice. Swap to fresh blades, and make sure your washer fluid is rated for freezing temperatures — the summer stuff can freeze solid in the reservoir and lines.

6. Oil

Cold oil is thicker oil, and thicker oil takes longer to properly lubricate a cold engine on startup. If your manufacturer recommends a different viscosity for winter, or if you're due for a change anyway, going into the season with fresh oil is good timing — see our oil change page.

7. An emergency kit

Not a repair, but worth having in the car: an ice scraper, a blanket, a flashlight, and a phone charger. If you do get stuck, it makes the wait a lot more bearable.
