As temperatures drop and icy roads become a reality, preparing your vehicle for winter isn’t just smart — it’s essential. Whether you're commuting to campus or heading over a pass for a weekend getaway, knowing how to winterize your car can mean the difference between a smooth ride and a roadside emergency.
In this edition of “Ask the Expert,” we talk with Murray Ruggles, department head of YVC’s Automotive Service Technology (AST) program, about the must-dos, common mistakes and budget-friendly tips to keep your vehicle safe, reliable and ready for whatever winter throws your way.
Ruggles brings decades of experience to the classroom. Before joining YVC full time in 2013, he worked at his family’s business, Ruggles Auto Repair in Toppenish. He’s an ASE-certified master technician, a graduate of Universal Technical Institute in Phoenix, and a longtime instructor at YVC. In addition to teaching core courses, he advises the college’s SkillsUSA chapter and serves as a liaison to the Vintiques and Sun Country Mustang car clubs.

What does it mean to “winterize” your vehicle and why is it important — especially in our region?
Winterizing means preparing your vehicle for cold conditions — especially important in Central Washington, where winters can be harsh and snowy. The biggest concerns are traction and freezing temperatures. Fluids like coolant and windshield washer fluid can freeze if not properly maintained, potentially causing serious damage such as cracked engine blocks or broken components.
Switching to a winter blend washer fluid is key. Summer blends can freeze, making it difficult to clear your windshield and maintain visibility. Checking your tires, battery and heating system are also essential steps to ensure your vehicle is safe and reliable all season long.
When should drivers start preparing their vehicles for winter, and what are the first steps they should take?
Drivers should begin preparing their vehicles for winter in early fall — ideally by September. This gives you time to complete any needed maintenance before colder weather hits, especially if your next service falls in December, January or February.
Review your vehicle’s service schedule and address areas affected by cold weather. A good shop will begin discussing winter prep during fall appointments. Key checks include your coolant system, washer fluid, and tire condition.
What are the most common mistakes people make when winterizing their cars, and how can they avoid them?
One of the biggest mistakes drivers make is waiting too long to prepare. Delaying maintenance until the next scheduled service can cause overlap with colder months, when issues are more likely to arise. Shops are generally proactive in making seasonal recommendations, but procrastination — especially without budgeting for potential costs — can leave drivers unprepared.
Heating and air conditioning systems are also more likely to fail when they’re needed most. Unexpected repairs during winter can catch drivers off guard financially. To avoid surprises, it’s best to schedule a fall checkup and address any concerns before temperatures drop.

How can drivers check if their tires are winter-ready, and what’s the difference between snow tires and all-season tires?
Start by checking tread depth and tire pressure. Good tread improves traction, and proper inflation helps maintain control. Also, consider the age and mileage of your tires — even if they haven’t been driven much, rubber degrades over time. Most tires last about four to five years with average use.
The main difference between snow tires and all-season tires is the rubber compound
and tread design. Snow tires are made with softer rubber that stays flexible in cold
temperatures, offering better grip on snow and ice. However, they tend to wear faster
when used on dry pavement. All-season tires have a harder tread and are designed for
year-round use, making them a practical choice for most drivers in the Yakima area.
What are some signs a battery might be on its last leg, and what should drivers do
to prevent getting stranded out in the cold?
Cold weather can expose battery issues that weren’t noticeable in warmer months. A slow
engine crank is often the first sign your battery may be failing. If your vehicle
sounds sluggish when starting, it’s time to have the battery tested.
Batteries are affected by both heat and cold, and their lifespan typically ranges from three to six years. If yours is nearing the end of its lifespan, have it tested before winter. Many shops offer free battery checks, and replacing a weak battery early can prevent a costly tow or roadside emergency.
What should be included in a winter emergency kit for your car, and how can students
on a budget put one together affordably?
Winter driving requires preparation — and having the right tools on hand can make
a big difference. At minimum, every vehicle should be equipped with an ice scraper,
snow brush and gloves.
Safety kits are widely available and often include reflective gear, flares and other emergency items. It’s also smart to carry a small container of sand or kitty litter — to help gain traction if you get stuck.
Additional items that may be helpful are jumper cables or a portable jump pack. While jumper cables are useful, they must be used with caution to avoid damaging either vehicle. Portable jump packs are a safer alternative and are now widely available at affordable prices.
Are there any special considerations for electric or hybrid vehicles when it comes
to winter prep?
Yes, electric and hybrid vehicles require special attention during winter months.
One key consideration is reduced driving range. In cold weather, these vehicles use
additional energy to maintain battery and cabin temperatures, which can significantly
impact how far you can travel on a single charge.
Both electric and hybrid vehicles have cooling systems that often use traditional coolant. These systems should be inspected and serviced regularly to ensure proper function in freezing temperatures. In hybrids, the cooling system for the battery may be separate from the engine’s cooling system, so it’s important to have both checked during seasonal maintenance.
What maintenance tips do you recommend for keeping your car running smoothly throughout
the winter months?
Regular maintenance is key to keeping your vehicle reliable during winter. Start by
following your manufacturer’s recommended service schedule and consider having a multipoint
inspection performed by a trusted shop. A good service provider will help monitor
wear and tear and make seasonal recommendations — a smart business practice that benefits
both the shop and the customer.
Fuel additives can help keep the system clean, though they’re not as critical as they once were due to improvements in fuel quality. If you're considering additives, ask your technician about reputable products like BG.
Don’t overlook your windshield wipers. Streaky windows can be a nuisance and a safety hazard. Winter-specific wipers with protective boots are designed to perform better in cold conditions and should be replaced annually.
Also, avoid letting your vehicle sit unused for long periods, as inactivity can be hard on the engine and other systems. Stay on top of oil changes and inspections to ensure your car is ready for whatever winter throws your way.

What advice would you give to first-time drivers or students who may be experiencing
their first winter behind the wheel?
First-time drivers should take extra precautions during winter to stay safe and avoid
common mistakes.
Always clear your windshield completely before driving — front and rear — and allow your engine time to warm up. If you're short on time, consider using a plastic windshield cover to prevent ice buildup overnight.
Before driving, scrape snow off all windows and ensure your wipers are free of ice. Replace worn wipers with winter-specific blades that feature protective boots for better performance in cold conditions.
Plan for extra travel time and adjust your driving habits. On slick roads, begin slowing down well in advance of stops to reduce strain on your brakes and improve control.
