When the real cold arrives, Your car suffers much more than it seemsEven though it looks exactly the same as in summer, low temperatures, humidity, road salt, ice, and snow gradually take their toll on key components like the battery, tires, engine, and braking system. If you don't take care of them, you could end up in the shop at the worst possible time. To minimize risks, consult our Tips for driving in winter.
In addition to the breakdowns, Driving risks increase in winter.There are fewer hours of daylight, and heavy rain, fog, ice, and nighttime frosts are common. That's why it's a good idea to prepare your car well in advance and follow a few simple tips that extend the life of your vehicle and allow you to drive with much greater peace of mind when the temperature drops. If you want more information on safety in adverse conditions, consult our guide. Safe driving on trips.
1. Park under cover and protect the car body
A detail as simple as to store the car in a garage or under a porch It makes a big difference in winter. A vehicle that spends the night indoors starts better, suffers fewer sudden temperature changes, and is better protected from ice, wind, rain, and snow than one that always "sleeps" on the street; in addition, applying some Tricks to heat your car in winter can further improve the morning start.
When you don't have that option, Try to park in the most sheltered spot you can find.Avoid areas heavily exposed to drafts or where humidity accumulates. While it might seem trivial, finding a facade that acts as a windbreak or a tree that blocks the wind helps keep the car cooler. If you're concerned about the impact of the weather on your vehicle, also check out information on... weather damage and car insurance.
For cars that are always outdoors, a good car cover or tarpaulin It's a highly recommended investment. These covers protect the paintwork from salt and gravel, reduce ice formation on the bodywork and windows, and also prevent the accumulation of dirt that can cause corrosion over time.
It is also advisable at this time of year Wash the car regularly to remove salt residue. and mud. In winter, roads are treated with salt and other products that stick to undercarriages, wheel wells, and fenders. If you don't remove them, over the years rust and structural damage can appear, especially on older vehicles; it's a form of avoid the most expensive breakdowns.
2. Battery: the major weak point at low temperatures
With the cold, The battery is probably the component that suffers the most.Internal chemical reactions become less efficient, and the battery's actual capacity drops sharply, precisely when the car needs the most energy to start and power systems like the heater, rear window defroster, and defrosters. If you run out of charge, learn how to start a car without a battery in a safe way.
If your battery is a few years old, It's a good idea to have it checked at a workshop before winterIn many cases, performance starts to decline after three years, and after five years the likelihood of being stranded on a freezing morning increases significantly. A professional can check its charge, the condition of the terminals, and whether it needs replacing.
There's a home trick that can help you in very cold climates: Place a dry, warm cloth over the battery for a few minutes. before attempting to start the engine. This slight increase in temperature can facilitate starting when the battery is at its limit, although it does not replace proper maintenance.
It is also important Always keep jumper cables in the trunkThey're inexpensive, take up almost no space, and can get you out of a tight spot if your battery decides to let you down in a parking lot or on the street. Take the opportunity to visually inspect the terminals to ensure they're clean and free of rust and sulfation.
3. Engine oil and other fluids: prevent the cold from blocking the engine.
In winter, The engine oil becomes thickerIt takes longer to circulate and lubricate all the moving parts. If the lubricant is very degraded or not recommended for low temperatures, the engine's effort during cold starts increases, and internal wear is also accelerated.
Ideally Always use the viscosity and type of oil specified by the manufacturerAnd consider using multigrade or slightly less viscous oils when the car will be driven frequently in very low temperatures. These lubricants facilitate winter starts because they flow better in cold weather and provide better protection from the very first seconds.
It is also convenient respect the oil change intervalsAs a general guideline, many manufacturers recommend around 20.000 km or two years, but this can vary depending on the model, driving style, and mileage. If you can't remember when you last changed it or notice the oil is very dark and thick, take your car to your trusted mechanic for a checkup.
Beyond engine oil, there are other fluids you should also keep an eye on: brake fluid, power steering fluid and coolantThey all need to reach a minimum temperature to function correctly, so it's not a good idea to start the engine and drive off. Letting the engine idle for a minute or two helps these fluids flow and ensures proper lubrication.
4. Coolant and antifreeze: key defense against ice
The cooling circuit works daily, even in winter, and The coolant also acts as antifreeze.Its mission is to maintain the engine temperature within an optimal range, prevent the water from freezing, and protect the interior of the circuit from corrosion.
Over time, The refrigerant loses its properties and gets dirty.That's why it's recommended to change it approximately every three years or every 60.000 km, always checking the level and, very importantly, the appearance of the fluid: if you see it cloudy, with a strange color or too translucent, it needs to be replaced.
There are different types and colors of antifreezeThese markings indicate the concentration and temperature the product can withstand. The most diluted solutions (for example, mixtures close to 10% product and 90% distilled water) can withstand around -4°C, while 50% mixtures can withstand temperatures as low as -36°C. It is essential not to mix different colors and to always use a product compatible with your vehicle.
Avoid filling the circuit with water only. because in winter pure water can freeze and cause very serious damage to the engine and radiator. Adjusting the correct antifreeze ratio not only prevents ice formation, but also protects against scale buildup and internal rust, extending the life of the cooling and heating system.
5. Tires: grip and safety on water, snow and ice
Tires are the only real point of contact between the car and the asphaltAnd in winter they have to face heavy rain, puddles, snow, ice, and sleet. Their condition is crucial for braking in time, avoiding hydroplaning, and maintaining vehicle control; if you have any doubts, here are some tips for choosing the right tires.
Before the intense cold arrives, Check the drawing and the depth of the profile.For safe winter driving, it's recommended to have at least 3 mm of tread depth, although the legal minimum is 1,6 mm. When the tread is very worn, the tire's water evacuation rate is reduced, making driving on slippery surfaces critical. If you have any doubts about when to replace them, consult your tire specialist. when to change the wheels.
In many countries, and in some specific areas, Is it mandatory or highly advisable to fit winter tires? During the colder months, these tires have a softer compound and a special tread design with more sipes, which improves grip on snow, ice, and mud. Always look for the M+S (mud & snow) marking or the snowflake symbol with the three peaks, which guarantees that they meet winter standards.
If you opt for winter or “all season” tires, Always exchange them for sets of fournot just the front or rear axle. Mixing summer and winter tires on the same car unbalances handling and can create dangerous situations, especially during emergency braking or sudden maneuvers.
Also, don't forget to check tire pressure more frequentlyCold weather reduces internal tire pressure, making it easy to drive with less than the recommended pressure, which increases fuel consumption and reduces grip. Check your tire pressure at least once a month, always when the tires are cold. Also, keep in mind the influence of winter tires in consumption.
If you live in areas where it snows frequently or you often go to the mountains, carry snow chains or equivalent devices in the trunk It's mandatory on many roads and, above all, an important safety measure. Make sure you know how to put them on before you need them in the middle of a snowstorm.
6. Brakes, shock absorption and safety systems
In winter, Braking distance is increased by humidity, ice, and snowTherefore, having your brakes in perfect working order becomes even more important than the rest of the year. A few extra meters can make the difference between a close call and an accident.
It agrees Periodically check the wear on brake pads and discs.as well as the condition of the brake fluid. If it's very old or dirty, its boiling point drops and it can lose effectiveness during hard braking. If you notice vibrations in the pedal, noises when braking, or a sluggish response, have your brakes checked at your garage as soon as possible.
The suspension system and shock absorbers also play a key role. Worn shock absorbers increase the risk of hydroplaningBecause the wheel loses contact with the asphalt when driving over puddles or uneven surfaces. Furthermore, they worsen the vehicle's stability in curves and during braking, precisely when it's least needed.
In very cold areas, some parts of the braking system may to freeze or work with difficulty if they accumulate water, salt, or dirt. Hence the importance of preventative maintenance: a general check-up before winter can detect small problems in time that would worsen with the cold.
7. Windshield, windshield wipers and visibility
Visibility is crucial during periods of rain, fog, and snow, so windshield, rear window defroster and wiper blades must be in good conditionAny small impact on the glass can turn into a crack if it undergoes a sudden temperature change. To find out how prevent the windows from freezing You have a series of practical recommendations.
To prevent the windshield wiper blades from sticking to the glass during frost, Many people recommend leaving them up when parkingAnother practical option is to place a small cork or support system that keeps the rubber somewhat separated from the glass, reducing the risk of it breaking when activated in the morning.
A very effective trick is Use a specific windshield cover or protector at nightThis way, when you arrive in the morning, you'll only need to remove the cover, and you'll have avoided much of the frost and ice. Never use boiling water to melt ice, as the temperature difference can crack the glass immediately. Also, fill the windshield washer fluid reservoir with appropriate products, following the instructions. Best tricks to prevent windows from fogging up.
Brushes also age due to cold, sun, and intensive use. If they leave areas uncleaned, they make noise or "jump" on the glassIt's time to change them. Worn tires significantly reduce visibility in heavy rain or snow, which is the last thing you want in winter.
In addition, it is advisable Fill the windshield washer fluid reservoir with a specific fluid that includes antifreeze.Never use just water, as it can freeze inside the system, clog it, or even damage the pump. Also, check the condition of the rear window defroster, which greatly helps to defrost and remove frost quickly.
8. Lighting and air conditioning systems
During the cold months, The days are shorter and people drive many more hours at night or in poor lighting conditions.Fog, heavy rain, and snow reduce visibility, both for you and other drivers, so your lighting system needs to work perfectly.
It is recommended Check all vehicle lightsLow beams, high beams, turn signals, brake lights, reverse lights, front and rear fog lights. Replace any burned-out bulbs, clean the headlights frequently to remove mud and salt, and check that the headlights are properly adjusted to avoid dazzling other drivers or insufficient illumination.
On the other hand, air conditioning is not just for comfort. A heating and air conditioning system in good working order helps to defog and defrost the windows Much faster, while maintaining a clear view. Regarding potential failures and their prevention, review information on air conditioning and heating breakdowns.
You should check the heater core and the cooling system. They should not have obstructions or dirt depositsIn some cases, cleaning with specific descaling products can restore lost performance. If this system is not maintained, a radiator breakdown can be quite costly.
9. Cold starts: how to take care of your engine on the worst days
The first few seconds after turning the key or pressing the start button are the moment when the mechanics suffer the mostEspecially in the dead of winter. The oil is cold and thick, the metal components contract due to the temperature, and the battery is working at full capacity to power the starter motor. For safe and efficient starting, see how Start your car in winter without damaging it..
The most advisable is Avoid revving the engine immediately after startingLet it idle for one to three minutes, enough time for the oil to circulate and the fluids to reach a minimum temperature. Then, start driving gently, without sudden acceleration or flooring the accelerator in the first few blocks.
It also helps a lot Ensure the air and fuel filters are in good conditionA dirty air filter restricts oxygen intake and impairs combustion, while a clogged fuel filter can cause jerking and make starting difficult. Including their inspection as part of your winter maintenance is a good habit.
In vehicles with automatic stop and start (start-stop) systems, The demands on the battery and starter motor are even greaterIf you make many short urban journeys, with constant stops at traffic lights, the wear and tear is accentuated, so preventive maintenance is especially important in these cases.
10. Winter emergency kit and accessories
An important part of car care in winter involves bring the appropriate equipment for unforeseen eventsA simple winter kit can get you out of more than one tight spot if you get caught in a snowstorm, a severe frost, or a traffic jam.
That kit should include: a scraper specifically designed for ice and a soft-bristled brush to remove snow without scratching the windows. Also add a sunshade or anti-freeze blanket for the windshield, which will reduce nighttime frost, and good snow chains or textile covers if you often drive in areas with frequent snowfall.
In addition to car accessories, it is recommended Bring blankets, warm clothes, gloves, and a hat If you're going on long trips in the middle of winter, complete your kit with a flashlight with good batteries, some water, non-perishable food, a small first-aid kit, and of course, a fully charged mobile phone and, if possible, a car charger.
Other very useful items in harsh climates are a small folding shovel, a set of battery clamps, and some spare antifreeze.These are objects that take up hardly any space and can make all the difference if you need to get your car out of the snow, start it with the help of another vehicle, or refill the fuel tank at a crucial moment.
Taking all of this into account, Preparing your car for winter is much more than simple maintenanceIt's a way to gain peace of mind, avoid costly breakdowns, and reduce risks on the road when conditions turn bad. If you check the battery, tires, brake system, oil, antifreeze, visibility, lights, and carry a good emergency kit, your car will be ready to face the cold, rain, ice, and snow while you just focus on enjoying the trip.
