Winter car maintenance should focus on the systems cold weather stresses most: the battery, tires, cooling system, brakes, wipers, washer fluid, lights and engine fluids.
Have the battery checked if it is aging or starting slowly, maintain correct tire pressure, confirm the coolant provides proper freeze protection, replace worn wiper blades, use winter-rated washer fluid and keep scheduled maintenance current.
A vehicle that seems fine in mild weather can expose a weak battery, marginal tire or cooling-system problem as soon as temperatures fall. A pre-winter inspection gives you time to correct problems before they become roadside emergencies.
Cold weather can expose a battery that was already getting weak.
Starting an engine requires substantial electrical power, and battery performance falls as temperatures drop. If the engine cranks slowly, the battery is several years old or you have needed a jump-start recently, have the battery and charging system tested before winter.
Slow cranking, dim lights during startup, repeated jump-starts and battery or charging warnings deserve attention. A battery problem can also be caused by the alternator, connections or an electrical draw, so testing is better than guessing.
Tire pressure changes with temperature, and winter traction depends on good tire condition.
As outside temperatures fall, tire pressure typically drops. Check pressure when the tires are cold and inflate them to the vehicle manufacturer's specification shown on the driver's-door placard or owner's manual—not the maximum pressure molded into the tire sidewall.
Look for worn tread, cracking, bulges, punctures and uneven wear. Drivers who regularly encounter snow or ice should consider whether their tire type and remaining tread are appropriate for those conditions.
Coolant protects the engine in winter as well as summer.
The cooling system needs the correct coolant mixture and proper level to help prevent freezing, corrosion and overheating. Old coolant, leaks, a weak thermostat or deteriorated hoses can create problems when temperatures become extreme.
- Check coolant level only according to the manufacturer's safety instructions
- Inspect for visible coolant leaks or recurring low coolant
- Follow the correct coolant type and service interval for your vehicle
- Have freeze protection checked if coolant condition or mixture is uncertain
- Do not open a hot pressurized cooling system
Wipers, washer fluid and lights matter more when days are short and roads are dirty.
Replace wiper blades that streak, chatter or leave areas of the windshield uncleared. Keep the washer reservoir filled with fluid suitable for freezing temperatures, and check headlights, brake lights, turn signals and other exterior lighting.
Remove snow and ice from windows, mirrors, lights and the vehicle body so you can see clearly and so loose snow or ice does not become a hazard to other road users.
Winter is not the time to discover your brakes or maintenance items were already overdue.
If you hear grinding or squealing, feel vibration while braking, notice pulling or have a brake warning light, schedule an inspection. Keep engine oil and other manufacturer-specified fluids current as well.
Modern vehicles have different oil specifications and maintenance schedules. Use the viscosity and specification required by your manufacturer rather than switching oil simply because winter has arrived.
Eight things worth checking before the coldest weather arrives.
Test starting and charging performance
Especially important for an older battery or a vehicle that cranks slowly.
Check pressure, tread and condition
Cold temperatures reduce pressure and worn tires reduce available traction.
Verify level and freeze protection
Correct coolant helps protect against freezing, corrosion and overheating.
Replace streaking blades
Clear visibility is essential in rain, snow, road spray and darkness.
Use freeze-resistant fluid
Keep the reservoir full and confirm the washers operate properly.
Check exterior illumination
Winter brings longer hours of darkness and frequently reduced visibility.
Address noises and vibration
Do not postpone known brake problems before winter driving conditions.
Prepare for delays
Carry season-appropriate essentials such as warm clothing, a flashlight, phone charging capability and other supplies appropriate to your travel.

Schedule Winter Maintenance →Winter car maintenance questions.
Check the battery, tires and pressure, coolant, brakes, wipers, washer fluid, lights and scheduled engine maintenance before cold weather becomes severe.
Cold temperatures reduce a battery's available performance while the engine can require substantial power to start. Winter often exposes batteries that were already weak or aging.
Yes. Tire pressure generally decreases as ambient temperature falls. Check pressure when the tires are cold and use the vehicle manufacturer's recommended pressure.
Use the coolant type and mixture specified for your vehicle. Proper coolant concentration provides freeze protection as well as corrosion and overheating protection.
Change the oil when it is due and use the viscosity and specification required by the vehicle manufacturer. Modern vehicles should not automatically receive a different oil solely because winter has arrived.
Use automotive washer fluid rated for temperatures expected in your area rather than plain water, which can freeze.
Consider warm clothing or a blanket, flashlight, phone charging capability and other emergency supplies appropriate to your route, weather and travel conditions.
