Winter is a time of snow-filled adventures and frosty mornings. If the wild is calling to you to trek forward into the glittering white horizon, your Grenadier is ready to tag along, conquering anything winter throws its way.
However, just like any other machine—no matter how tough and ready—a little prep goes a long way. Whether navigating icy roads, trudging through snowdrifts, or just making sure your vehicle stays in top shape, here are some winter maintenance tips for your INEOS Grenadier to keep it performing at its best.
Check and Replace Antifreeze
Antifreeze is your Grenadier’s best friend when temperatures drop, lowering your car’s freezing point and keeping the system from turning into a block of ice. Check that your coolant levels are sufficient and that the mixture is balanced at the right ratio to prevent freezing or overheating.
A half-and-half mix of antifreeze and water is your typical ratio, but always double-check your owner’s manual for the specifics. In even colder conditions, you can run a 70/30 mix or use an antifreeze rated for temperatures of -34 degrees Fahrenheit. If you haven’t replaced the antifreeze in a while or if it looks cloudy, it’s time to drain and refill it.
Use the Correct Oil
Using the right oil for your car is crucial, especially during colder months. As temperatures drop, oil tends to thicken, which can make it harder for your engine to start and run smoothly. Fortunately, you don’t have to go digging around the internet to find the perfect oil grade.
With a Grenadier, take a quick peek at your manufacturer’s guide and you’ll see that your oil is already properly temperature-rated for winter. Regular oil changes and using the right oil type are simple steps to ensure your car stays in top shape all winter long.
Replace Windshield Wipers and Add Winter Washer Fluid
Winter weather can be tough on your windshield wipers, so replace them with heavy-duty ones that can handle snow and ice. Pair those new wipers with winter washer fluid that won’t freeze in low temperatures. Winter formulas typically include methanol—a kind of alcohol—to keep the liquid from freezing, as well as a deicing agent so you’ll have a clear view, even in the harshest conditions.
This simple change can make a big difference when you’re cruising through frosty landscapes or tackling slushy roads. Staying proactive with your wipers and fluid provides better visibility and safer drives all season long.
Maintain a Full Tank of Fuel
Keeping your gas tank full during the winter isn’t just about avoiding running out of fuel; it’s also an important step in preventing potential problems. A fuller tank reduces the chances of moisture building up inside, which can freeze during cold weather and lead to complications in your fuel lines.
You should also consider proper maintenance, such as using a fuel injection cleaner or an additive to keep the fuel injection system clean, which is especially important during the winter months. In the cold, ethanol may start to break down if you leave it in the tank for around 90 days.
Inspect Your Battery and Electrical System
Cold weather can be tough on your car battery, cutting down the electrochemical reaction it needs to produce power. Give your battery some attention before winter fully sets in, checking the battery’s charge and inspecting it for signs of corrosion on the terminals.
Clean connections and a strong charge help your vehicle start reliably on frosty mornings. Don’t forget to test your electrical system as well, including lights, heaters, and wipers, to make sure everything is in good working order.
Inspect Belts and Hoses
Winter can be especially hard on your Grenadier’s belts and hoses, as the cold temperatures can make the rubber frail and brittle. Look for signs of wear, such as cracks, fraying, or glazing, as these issues can weaken the components and lead to failure in colder conditions. Pay special attention to the tension of the belts, checking that they aren’t too loose or too tight, as either can cause issues. Hoses should be firm but not taut or rigid, with no signs of leaks or bulges.
Swap to Winter or All-Terrain Tires
Winter tires are a game changer when it comes to navigating icy or snow-covered roads with confidence. Unlike regular tires, the winter variety has special rubber compounds that stay flexible in low temperatures, giving you better grip and control. The tread patterns on winter tires are much deeper, with more notches than your average tire, helping channel away snow and slush and reducing the risk of sliding.
If you live in an area with harsh winters, swapping to winter tires is a must, but even all-terrain tires can offer improved performance in mild winter conditions. Check the tire pressure regularly, as it tends to drop with the temperature, to get the best performance throughout the season.
Install Snow Chains if Necessary
Snow chains can make a world of difference when driving on icy or snow-packed roads, offering the extra traction needed to keep you safe. They’re not just for mountain adventures; if your area experiences heavy snowfall, having a set on hand is always a smart idea. Before winter weather hits, take a few minutes to practice putting snow chains on your Grenadier so you’re not fumbling with cold hands in freezing conditions.
Make sure the chains are the right size for your tires, and inspect chains for wear or damage before use. When driving with snow chains, remember to keep your speed lower. Also, avoid suddenly braking or accelerating to help the snow chains do their job effectively. With chains ready to go, you’ll feel more prepared to tackle slippery, wintry roads this season.
Look Over the Heating System
There’s nothing worse than stepping into a cold car and waiting to heat up your freezing fingers so you can grip the wheel comfortably. Your Grenadier’s heating system is key to staying warm and comfortable during chilly drives, so it’s worth giving it some attention before winter hits full swing.
Test the heater to ensure it’s blowing warm air effectively. If the air feels lukewarm, heats too slowly, or isn’t working at all, it might be time to check the coolant levels or have a professional inspect the system. Don’t forget about the defroster too; clear windows are essential for safe driving in cold weather. A quick check now can save you from an icy surprise when the temperatures drop later.
Check the 4×4 System
A properly functioning 4×4 system majorly helps when navigating through snow, ice, or muddy terrain during winter. Before you head out into challenging conditions, check that your system is in good working order. It should engage smoothly and not make unusual noises.
If you’re unfamiliar with the system or if you haven’t used it in a while, consulting your vehicle’s manual is a great place to start. A solid, fully functioning 4×4 system can boost your confidence and keep you moving steadily all winter long.
