Seasonal Car Maintenance Checklist
Written by Muneeb Rana · Last updated 21 October 2026
Quick answer: Seasonal car maintenance means preparing for temperature extremes. Before winter: test the battery, check antifreeze, fit winter or all-weather tires if needed, replace wipers and pack an emergency kit. Before summer: check coolant, AC, tire pressure and tread, and the battery, since heat also shortens battery life.
TL;DR
- Winter: battery, coolant, tires, wipers, emergency kit.
- Summer: coolant, AC, tires, battery.
- Recheck tire pressure as temperatures change.
Seasonal car maintenance takes an hour twice a year and prevents the most common weather breakdowns: flat batteries in the cold and overheating in the heat. Use these two checklists in autumn and spring.
Winter checklist
- Battery: get it tested if it's three or more years old; cold reduces cranking power (car battery life).
- Coolant/antifreeze: correct level and mix (coolant flush).
- Tires: tread depth, pressure (it drops about 1 PSI per 10°F), and winter tires where conditions call for them.
- Wipers and washer fluid rated for freezing temperatures.
- Lights clean and working.
- Emergency kit: scraper, blanket, torch, phone charger, jumper cables, snacks.
Summer checklist
- Coolant level and hoses: overheating is a top summer breakdown cause. Know what the coolant temperature light means.
- Air conditioning blowing cold.
- Tires: pressure and tread before road trips. NHTSA's summer driving tips recommend checking tires, battery, belts and fluids before long trips.
- Battery: heat speeds up battery failure too.
- Wiper blades cracked by winter.
Before a road trip
Add an oil level check, a look at brakes, and a plan for fuel costs with the fuel cost calculator. If a service is due soon, do it before you leave.

FAQ
How do I prepare my car for winter?
Test the battery, check coolant, inspect tires (consider winter tires), replace wipers, use winter washer fluid and pack an emergency kit.
Does cold weather affect tire pressure?
Yes, pressure drops about 1 PSI for every 10°F fall. Recheck tires when the weather turns cold.
What should I check before a summer road trip?
Tires, coolant, oil, battery, brakes, belts, lights and AC. Service the car first if it's nearly due.
Do I need winter tires?
In places with regular snow and ice, winter tires grip much better than all-season tires. In milder climates, good all-season or all-weather tires may be enough.
Why do car batteries fail in winter?
Cold slows the battery's chemistry and thickens oil, so starting needs more power from a weaker battery. Heat damage from summer often shows up as a winter failure.
