Getting Your Car Ready for Winter: Essential
Maintenance Tips

Winter can be particularly challenging for vehicles, with cold temperatures, icy roads, and
snowfall all contributing to potentially dangerous driving conditions. Preparing your car for
winter is essential for both your safety and the longevity of your vehicle.

Here, we’ll discuss the most important winter maintenance tips to keep your car running
smoothly and safely, covering everything from tire maintenance to fluid checks and more.

1. Check and Change Your Tires for Winter Conditions
Winter Tire Benefits
Winter tires provide extra grip in snowy and icy conditions, greatly enhancing safety and
performance. Unlike regular tires, winter tires are made with a softer rubber compound that
remains flexible even in freezing temperatures. This flexibility ensures that the tires can grip the
road more effectively, reducing the likelihood of slipping or losing control.

Checking Tire Tread and Pressure
If you already have all-season or winter tires, inspect the tread depth. A tread depth of at least
6/32 inches is recommended for safe driving in snowy conditions. Use a tread depth gauge or
the penny test: insert a penny into the tread, with Lincoln’s head down. If you can see his entire
head, it’s time to replace the tires.

Cold temperatures can cause tire pressure to drop, so check your tires often throughout winter
and ensure they’re inflated to the manufacturer’s recommended pressure. Properly inflated
tires provide better traction, handling, and fuel efficiency.

2. Inspect and Replace Your Car Battery
Cold Weather and Battery Performance
Cold weather can weaken your car’s battery, making it harder for your engine to start. Batteries
lose about 35% of their strength at 32°F and can lose up to 60% at 0°F. If your battery is older
than three years, consider getting it tested at Guerrero Tire Shop to ensure it’s strong enough
to withstand the winter.

Visual Inspection and Terminal Cleaning
Inspect your battery terminals for corrosion. Clean off any white or greenish buildup around the
terminals, as corrosion can hinder your battery’s performance. You can use a battery terminal
cleaner, baking soda, or a solution designed for terminal cleaning. Make sure the battery is
tightly secured and the connections are snug.

3. Keep an Eye on Fluids
Fluids play a crucial role in your car’s performance, especially in winter. Here’s what to check:

Engine Oil: Consider switching to a winter-grade oil, which has a lower viscosity for easier starts
in cold weather. For example, 5W-30 or 0W-20 oils are ideal for cold conditions.
Antifreeze/Coolant: Your engine needs antifreeze to prevent freezing in cold temperatures.
Check that the coolant levels are adequate and use a 50/50 mix of antifreeze and water for
optimal performance.
Windshield Washer Fluid: Use a winter formula that won’t freeze in cold weather. This fluid
keeps your windshield clear of snow, salt, and road grime, improving visibility.
Regularly top off these fluids and monitor their levels throughout the season.

4. Inspect and Replace Wiper Blades
Visibility is critical in winter, as snow, sleet, and salt can quickly obscure your view. Wiper
blades typically last six months to a year, so consider replacing them before winter if they’re
worn. Choose winter wiper blades, which are specifically designed to withstand snow and ice
buildup. Additionally, ensure that your washer fluid is a winter mix to prevent freezing on the
windshield.

5. Protect Your Car’s Exterior
The salt and sand used to treat roads can be corrosive to your car’s paint and undercarriage. To
protect your car:

Waxing: Apply a coat of wax to create a barrier against salt and road grime.
Undercarriage Protection: Consider an undercarriage wash and treatment to prevent rust and
corrosion.
Regular Washes: Rinse your car regularly to remove salt buildup, especially on the underside.
Maintaining your car’s exterior during winter helps preserve its appearance and resale value.

6. Test Your Car’s Heating System
A functioning heater is essential for comfortable driving in winter. Ensure that the heating
system is working effectively by testing it before the cold weather hits. If the air feels cool or
takes a long time to warm up, have a professional check your heating system.

7. Check Your Lights and Electrical System
With shorter daylight hours and low-visibility conditions, it’s vital that your car’s lights are in
top condition:

Headlights and Taillights: Ensure all exterior lights are functioning. Consider upgrading to
brighter bulbs if your lights seem dim.
Battery Voltage and Connections: Check your battery voltage and ensure all connections are
corrosion-free.
Good lighting improves your visibility and ensures that other drivers can see you.

8. Prepare an Emergency Winter Kit
Even with thorough preparation, winter driving can be unpredictable. Create an emergency kit
for your car that includes:

Blanket and warm clothing
Non-perishable food and water
Flashlight with extra batteries
Ice scraper and snow brush
Jumper cables
First aid kit
Tire chains (if permitted in your area)
Sand or kitty litter for traction on ice
Having a well-stocked emergency kit can provide you with peace of mind in case of an
unexpected breakdown.

9. Inspect Brakes and Suspension
Winter conditions put additional strain on your brakes and suspension. Have your brake pads,
rotors, and suspension components inspected before the season. Ensure that the brakes are
responsive and the suspension is in good condition for handling icy and uneven road surfaces.

10. Top Off the Fuel Tank and Check Exhaust System
Keeping your fuel tank at least half full reduces the risk of the fuel line freezing and ensures that
you have enough fuel if you become stranded. Additionally, inspect your exhaust system for
leaks. A leaky exhaust system could lead to carbon monoxide buildup inside the cabin,
especially in winter when windows are closed.
