Why the seasons matter for a car
Most cars are built to cope with a wide range of weather, but the parts that wear quietly, such as batteries, wiper blades, tires and coolant, are often the ones that fail when conditions change. A short check before each season takes less time than dealing with a failure on a cold morning or in a downpour.
Climate varies a lot by region. Someone in a mild coastal area may never need winter gear, while a driver in a mountain town may need it for months. Treat the lists below as a starting point and adjust them to your local weather and your owner’s manual.
Year-round basics
A few checks apply in every season:
- Tire pressure. Air pressure changes with temperature, so a car that was fine in warm weather can be noticeably low after a cold snap. Checking tire pressure about once a month, and before long trips, is a sound habit.
- Lights. Walk around the car with the lights on and check headlights, brake lights, turn signals and fog lights if you have them. Ask someone to watch the brake lights, or reflect them off a wall or window.
- Wipers and washer fluid. Streaking or chattering blades should be replaced, and the washer reservoir should be kept topped up.
- Dashboard messages. Any lit warning lights should be understood before a season of hard driving, not after.
Spring: recover from winter
Spring is a good time to remove what winter left behind. Wash the underside and wheel wells to clear road salt, check for stone chips or rust starting on the paint, and inspect the tires for damage from potholes. If you use separate winter tires, this is typically when drivers switch back, and it is worth looking at tread depth before deciding whether a set still has a season left.
Check the wiper blades, which may have been stressed by ice, and have any alignment pull checked if the car drifts after a season of rough roads.
Summer: heat and long trips
Heat is hard on batteries, tires and cooling systems. Before summer:
- Look at the coolant level when the engine is cold, and have the cooling system checked if you have not done so in a while.
- Make sure the air conditioning blows cold; weak cooling can point to a problem worth having inspected.
- Inspect tire sidewalls for cracking, and keep pressures correct, since underinflated tires run hotter.
- Consider a sunshade for parked time, and keep drinking water in the car.
If you plan a long drive, a general service check beforehand is sensible, along with a look at your emergency kit.
Fall: prepare for darker, wetter weather
Shorter days mean more driving in the dark, so check that headlights are aimed properly and the lenses are not badly clouded. Replace tired wiper blades before the rainy season, because they matter most when you need them most.
Fall is also the time to test the battery. Batteries often weaken slowly over several years and then fail on the first cold morning. Many shops will test a battery for free or for a small fee. Check that the heater and defroster work, and that the rear window demister clears the glass.
If winter tires are used where you live, book the changeover early, since shops get busy at the first cold spell. The differences between summer tires, winter tires and all-season tires are worth understanding before you decide what suits your climate.
Winter: cold, ice and snow
Cold affects nearly everything in the car. Before winter:
- Check the antifreeze concentration, which keeps coolant from freezing. Your manual will say which type your car uses.
- Fill the washer reservoir with fluid rated for low temperatures.
- Keep the fuel tank reasonably full, which also helps in case you are delayed in traffic.
- Make sure all doors and trunk seals are in good condition so they do not freeze shut.
Keep an ice scraper and soft brush in the car, and clear all snow from the roof, windows and lights before driving. In snowy regions, add a small shovel, a blanket, gloves and a flashlight. Good habits for winter driving matter as much as equipment, and the same goes for cold starts, which put the most strain on an aging battery.
Gear that changes with the seasons
Rather than packing everything all year, rotate a few items:
- Cold season: scraper, brush, gloves, blanket, shovel, traction aid such as sand or mats if appropriate for your area.
- Hot season: water, sunshade, a light blanket or towel for hot seats.
- Rainy season: a spare umbrella and a microfiber cloth for fogged glass.
- All year: jumper cables or a jump starter, a flashlight, a basic first aid kit, a phone charger and a way to mark a roadside stop.
Making it routine
Pick a date for each season, such as the clock change or the first day of a month, and run through the lists above. Keep a note of the date and what you replaced. If you are unsure about something under the hood, a qualified mechanic can check it quickly during a regular service, and that is better than guessing.
