Don't Get Left in the Cold: A Comprehensive Guide to Winter Car Maintenance
Description
Cold weather car care is essential for keeping your vehicle safe and reliable during Utah's harsh winter months. Winter conditions put extra stress on every part of your car, from the battery to the tires, and proper preparation can prevent dangerous breakdowns and costly repairs.
Quick Winter Car Care Checklist:
- Battery - Test for full charge and check terminals for corrosion
- Fluids - Check antifreeze, use winter-grade oil, fill washer fluid
- Tires - Verify pressure weekly and ensure tread depth is 4/32" minimum
- Brakes - Get a professional inspection before winter
- Emergency Kit - Stock jumper cables, blankets, flashlight, and snacks
- Gas Tank - Keep at least half full to prevent fuel line issues
- Wipers - Replace worn blades and use winter washer fluid
- Heater - Test functionality before cold weather hits
- Lights - Clean lenses and replace dim bulbs
- Exterior - Wash regularly to remove corrosive road salt
The statistics are sobering. In 2023, there were 320 fatal crashes and over 22,000 injury crashes during snow and sleet conditions. Weather-related accidents account for 24% of crashes on icy or snowy roads, with 374 fatalities in 2020 alone.
Cold temperatures affect your car in specific ways. At 0°F, your battery has only half the cranking power it has at 80°F. Tire pressure drops by about 1 PSI for every 10-degree temperature decrease. Engine fluids thicken, making it harder for your car to start and run properly.
Whether you're driving through Salt Lake City's winter storms or heading into the mountains, preparing your vehicle isn't optional, it's a necessity. The good news? Most winter car care is straightforward and can save you from being stranded in dangerous conditions.

Essential Cold Weather Car Care: Under the Hood Checks
Winter in Utah doesn't mess around. When temperatures plunge, your engine faces challenges that simply don't exist during warmer months. Fluids turn sluggish and thick. Your battery loses strength. Your engine strains just to wake up on a cold morning.
This is why cold weather car care starts under the hood. These checks aren't just about keeping your car running, they're about keeping you safe. According to the Federal Highway Administration, weather-related crashes are serious business, with 24% occurring on icy or snowy roads. In 2020 alone, these conditions led to 374 fatalities. We don't want you becoming a statistic.
The Heart of Your Car: Battery Health
Your battery is what brings your car to life each morning. In winter, it's working overtime and often losing the battle.
Here's the harsh reality: at 0°F, your battery delivers only half the cranking power it has at 80°F. Meanwhile, your cold engine needs more power to start, not less. It's a cruel irony that catches thousands of drivers off guard every winter.
If you've noticed any sluggish starts during fall, don't ignore them. That's your battery telling you it's struggling. Most car batteries last between three to five years, but cold weather can expose weakness earlier. If your battery has hit the three-year mark, get it load-tested by a professional. This test shows whether it can still hold a charge and deliver the cranking amps your engine needs.
While you're checking the battery, look at the terminals. White or bluish corrosion around them blocks electrical flow and can prevent your car from starting. A wire brush and some baking soda solution usually clear it right up.
And here's a simple tip that saves countless headaches: keep a good set of jumper cables in your trunk. Even with perfect maintenance, batteries can fail. Being prepared means you're back on the road in minutes instead of waiting for a tow truck in freezing weather.
Crucial Winter Fluids
Think of winter fluids as your car's cold-weather wardrobe. Just like you wouldn't wear summer clothes in a blizzard, your car needs the right fluids to handle the cold.
Antifreeze is your first line of defense. Despite the name, it doesn't just prevent overheating in summer, it stops your coolant from freezing solid in winter. When water freezes, it expands. In your engine, that expansion can crack the engine block and cause thousands of dollars in damage. A proper 50/50 mix of antifreeze and distilled water protects your engine down to about -34°F. For extreme cold, you might need a 60/40 ratio, but always check your owner's manual first.
Engine oil tells another important story. Oil thickens when it's cold, turning into something closer to honey than the flowing liquid your engine needs. This makes your engine work harder to turn over and leaves parts poorly lubricated during those critical first seconds. Winter-grade oil (typically marked as 5W-20, 5W-30, or 10W-30) stays fluid at low temperatures. The "W" stands for winter, and that first number tells you how well it flows in the cold. Lower is better.
Windshield washer fluid might seem minor until you're driving behind a salt-spraying truck with a dirty windshield. Regular washer fluid can freeze solid on your windshield, turning a small problem into a dangerous one. Winter-blend fluid with de-icer keeps flowing and actually helps melt ice. Keep your reservoir topped off, you'll use more in winter than you expect.
Staying Warm: Heater & Defroster Check
Picture this: you're driving through a Midvale snowstorm, and your heater dies. Or worse, your defroster stops working and your windshield fogs over. These aren't just comfort issues, they're safety hazards.
Before the first serious cold snap, test your heating system. Turn it to high and make sure hot air flows strongly from all vents. The heat should kick in within a few minutes of starting your car. If you notice weak airflow, strange smells, or lukewarm air, something needs attention.
Your defroster deserves equal attention. Both front and rear defrosters should clear condensation and frost quickly. Your front defroster is especially critical. You can't safely drive what you can't see. Test it on a cold morning and make sure it clears your entire windshield, not just a small patch.
Here's a safety warning that could save your life: never warm up your car in a closed garage. Carbon monoxide is odorless, colorless, and deadly. It builds up fast in enclosed spaces. If you're ever stranded in your car waiting for help, make absolutely sure your exhaust pipe isn't blocked by snow. Run the engine only in short bursts, and crack a window for fresh air. Staying a bit cold is better than carbon monoxide poisoning.
Mastering Winter Roads: Tires, Brakes, and Control
The moment your tires meet an icy patch on a Utah road, you'll understand why traction, stopping power, and control are non-negotiable for safe winter driving. It's that heart-stopping second when you realize your car isn't responding quite like it should. We've all been there, and it's not a fun feeling.
Here's the reality: stopping distances increase dramatically on winter roads. What takes 100 feet on dry pavement might require 300 feet on ice. That's why maintaining proper tire condition and brake function isn't just about avoiding repair bills, it's about getting home safely to your family.
The golden rule for winter driving? Increase your following distance and then increase it some more. You'll need plenty of time to stop when conditions get dicey. For more helpful guidance on staying safe when the weather turns nasty, check out the NHTSA winter driving tips.
Tire Maintenance: Your First Line of Defense in Cold Weather Car Care
Your tires are literally where the rubber meets the road. They're your only connection to the pavement, which makes them your most important safety feature for cold weather car care. And winter throws a one-two punch at them: slippery conditions reduce traction, while cold temperatures steal air pressure.
Let's talk about that pressure loss first. For every 10-degree drop in temperature, your tires lose about 1 PSI (pound per square inch). That might not sound like much, but when Utah temperatures plummet from 50°F to 0°F, you're looking at a 5 PSI drop. Suddenly, those properly inflated tires from October are significantly underinflated by January.
Why does this matter? Underinflated tires don't grip the road properly. They compromise your handling, reduce your fuel efficiency, and can even be dangerous on icy roads. We recommend checking your tire pressure weekly during winter, or at least every other week. Your vehicle's recommended PSI is listed in your owner's manual or on a sticker inside the driver's door jamb. It takes just a few minutes with an inexpensive tire gauge, and it could save your life.
Now, about tire tread. You know those grooves in your tires? They're not just for looks, they channel water, slush, and snow away from the tire surface so the rubber can grip the road. When tread gets too shallow, your tires can't do their job. For winter driving, you need at least 4/32 of an inch of tread depth.
Here's a simple way to check: grab a quarter from your pocket and insert it into the tread groove with Washington's head pointing down. If you can see the top of George's head, your tread is too shallow and it's time for new tires. It's that simple.
The big question we hear at Peterson Auto Sales: "Do I really need winter tires, or are my all-season tires good enough?" It's a fair question, especially since winter tires are an investment. Here's the honest answer: all-season tires are designed to handle a variety of conditions, but they're a compromise. When temperatures drop below 45°F, the rubber compound in all-season tires starts to harden, losing flexibility and grip.
Winter tires (look for the mountain-snowflake symbol on the sidewall) use a softer rubber compound that stays flexible in freezing temperatures. They also have deeper tread patterns and more biting edges. The difference is significant: winter tires can improve acceleration from a complete stop by 33% and reduce your stopping distance by 30 feet. That's potentially the difference between stopping safely and sliding into an intersection.
Here's something that surprises people: a two-wheel drive car with good winter tires often has better traction than a four-wheel drive vehicle on all-season tires. Four-wheel drive helps you get moving, but it doesn't help you stop or turn. If you regularly drive in heavy snow or tackle our mountain passes, winter tires are worth every penny.
Stopping Power: Winter Brake Inspection
Your brakes might be working fine right now, but winter has a way of exposing weaknesses. And unlike a dying battery that gives you some warning with slow cranking, brake problems don't always announce themselves until it's too late. Especially on an icy road when you really need them.
Utah's winter roads are tough on brakes. The combination of snow, moisture, and all that road salt we use for de-icing creates the perfect recipe for rust and corrosion. Salt is particularly aggressive, eating away at brake rotors and causing them to become rough and uneven. This doesn't just affect braking performance, it can damage other components and lead to expensive repairs.
Before winter arrives, we always recommend a professional brake inspection. This isn't something you can easily check yourself. We'll look at your brake pads for wear, check your rotors for warping or corrosion, and make sure your brake fluid is in good condition.
Pay attention to the warning signs your brakes might be giving you. Squealing or grinding noises when you brake are red flags. So is a brake pedal that vibrates or feels spongy. If you notice your car pulling to one side when braking, or if your stopping distance seems longer than usual, don't wait, get it checked out.
Proper brake maintenance is a critical part of cold weather car care. When you're driving down a steep, icy hill or need to stop suddenly because someone slid into your lane, you want absolute confidence that your brakes will respond. We want that for you too, because we see you as more than just customers. You're our neighbor, and we you to get home safely this winter.
Be Prepared: Your Winter Emergency Plan
You've done everything right. You've checked your battery, topped off your fluids, inspected your tires. But here's the reality: even with the best cold weather car care, winter can throw you a curveball. A sudden blizzard rolling through the Wasatch Mountains, an unexpected breakdown on I-15, or hitting a patch of black ice can leave you stranded. And when you're sitting in a cold car on the side of the road, that's when preparation really matters.
The numbers tell a sobering story. Every year, 116,800 people are injured in vehicle crashes on snowy, slushy, or icy pavement. While we can't control the weather, we can control how ready we are to handle it. That's why we always tell our customers at Peterson Auto Sales: hope for the best, but prepare for the worst.

Building Your Winter Emergency Kit
Think of your winter emergency kit as your safety net. It's not about being paranoid, it's about being smart. We've seen too many situations where a simple item made the difference between a minor inconvenience and a dangerous situation.
Start with the basics for getting unstuck or helping yourself. Jumper cables or a portable jump starter are essential since cold weather is murder on batteries. A portable jump starter is even better because you don't need to flag down another driver. You'll also want an ice scraper and snow brush for clearing your windows and lights, plus a small snow shovel for digging out your tires.
For gaining traction when you're stuck, keep a bag of sand, kitty litter, or traction mats in your trunk. We've heard from countless customers who got themselves unstuck using these simple tools. A basic tool kit can help with minor repairs, and warning devices like flares or reflective triangles alert other drivers to your presence.
Now for staying safe and comfortable if you're stranded for a while. Warm blankets and extra gloves can be lifesavers if your heater stops working or you need to step outside. Pack non-perishable snacks like energy bars and granola, along with bottled water just fill the bottles only halfway to leave room for expansion if they freeze.
Keep a flashlight with extra batteries since winter days are short and you might need light to make repairs or signal for help. A brightly colored cloth tied to your antenna or window acts as a distress signal. Don't forget a first-aid kit for treating minor injuries, and make sure you have a phone charger ideally a portable power bank that doesn't rely on your car's battery.
The Half-Tank Rule and Other Precautions
Here's a winter driving rule that seems simple but makes a huge difference: never let your gas tank drop below half full. We call it the half-tank rule, and it serves two important purposes.
First, keeping your tank at least half full prevents condensation from forming inside the fuel lines. When that condensation freezes, it can block the lines and leave you stranded. Second, if you do get stuck somewhere, that extra fuel lets you run your engine periodically to stay warm without worrying about running out of gas.
For our electric vehicle owners around Midvale and Salt Lake City, winter presents its own challenges. Cold weather can significantly reduce your driving range, sometimes by 30% or more. The key is to keep your battery charged and minimize unnecessary battery drain. If you have access to a charger at home, plug in your EV overnight. This keeps the battery warm and ensures you start each day with a full charge.
Here's a pro tip for EV drivers: pre-condition your vehicle while it's still plugged in. Heat up the cabin and get everything ready before you unplug. This way, you're not draining your battery to warm up the car, which helps preserve your driving range for the actual trip.
Whether you're driving a gas-powered truck or an electric vehicle, these simple precautions can make winter driving much safer. At Peterson Auto Sales, we want you to enjoy the beautiful Utah winter, not just survive it. A little preparation goes a long way toward peace of mind.
Frequently Asked Questions about Winter Car Care
We get a lot of great questions from our customers here in Midvale about preparing their vehicles for Utah's unpredictable winters. Let's tackle some of the most common ones we hear about cold weather car care:
How often should I check my tire pressure in the winter?
This is one of the most important habits you can develop for winter driving safety. Since tire pressure drops by about 1 PSI for every 10-degree temperature decrease, and we all know how wildly Utah temperatures can swing in winter, we recommend checking your tire pressure at least once a week. If you're not quite that diligent, every two weeks is the absolute minimum.
Here's the thing: your tires might look fine, but they could be significantly underinflated without you realizing it. A tire that was properly inflated at 60°F could lose 3-4 PSI when temperatures drop to 20°F overnight. That's enough to affect your traction, handling, and fuel economy. Not to mention your safety on icy roads.
And don't forget about your spare tire! It needs the same attention. The last thing you want is to change a flat in freezing weather only to find your spare is also underinflated.
Are winter tires really necessary in Utah?
This is probably our most frequently asked question, and the honest answer is: it depends on where and how you drive. If you're commuting to downtown Salt Lake City on well-maintained roads, all-season tires might be adequate. But if you're heading up to the ski resorts every weekend, living in the foothills, or dealing with steep driveways and unplowed side streets, winter tires are a game-changer.
The performance difference is dramatic. Winter tires are 48% faster on ice while helping you avoid those scary side-skids. They can reduce your stopping distance by 30 feet which could be the difference between a close call and a collision. Winter tires use a special rubber compound that stays flexible in freezing temperatures, giving you significantly better grip on snow and ice. All-season tires, by contrast, harden in the cold and lose much of their effectiveness.
Think of it this way: a two-wheel drive car with good winter tires often outperforms a four-wheel drive vehicle on all-season tires. Four-wheel drive helps you go, but it doesn't help you stop. Winter tires help with both. For serious winter driving conditions, they're an essential part of cold weather car care in our region.
How can I protect my car's paint from road salt?
Road salt is a necessary evil in Utah winters. It keeps our roads passable, but it's incredibly corrosive to your vehicle's paint and metal components. Left unchecked, it causes rust and corrosion that can eat away at your car's body and undercarriage, leading to expensive repairs down the road.
The best defense is regular washing. We know it seems counterintuitive to wash your car when it's just going to get dirty again tomorrow, but frequent washing throughout winter is crucial. Try to wash your car every week or two, especially after driving on heavily salted roads. Pay special attention to the undercarriage, most car washes offer an undercarriage rinse option, and it's worth every penny. That's where salt accumulates in hard-to-reach areas and does the most damage.
Before winter arrives, apply a fresh coat of wax to your car's exterior. This creates a protective barrier between your paint and all the salt, slush, and grime winter throws at it. It's like putting on sunscreen before going to the beach, a little prevention goes a long way.
If you notice any chips or scratches in your paint, get them touched up quickly. These expose bare metal that's vulnerable to rust, especially when salt gets into the equation. A small paint chip can turn into a major rust problem if left untreated through a salty winter.
Conclusion
Winter in Utah is beautiful, but it demands respect. Especially when you're behind the wheel. Taking care of your car during the cold months isn't about being overly cautious; it's about being smart and prepared. Cold weather car care really boils down to a few key areas: keeping your battery charged and ready, maintaining the right fluids, ensuring your tires have proper pressure and tread, checking your brakes work properly, and always having an emergency kit in your trunk.
When you stay on top of these essentials, you're doing more than just protecting your vehicle from winter's harsh conditions. You're protecting yourself and your loved ones. You're avoiding those frustrating mornings when your car won't start. You're reducing your chances of sliding on an icy road because your tires aren't up to the task. You're making sure that if something does go wrong, you have what you need to stay safe and warm until help arrives.
