Winter in Rexburg isn’t for the faint of heart—snow, ice, and freezing temperatures can make driving tough. Whether you’re heading to campus, work, or home for the weekend, making sure your car is ready for Idaho winters can save you from breakdowns, accidents, and expensive repairs. Here’s a quick guide to help you get your car winter-ready this season.
1. Check Your Battery
Cold weather weakens your car battery’s ability to hold a charge. According to the AAA, car batteries lose about 60% of their strength at 0°F. If your engine cranks slowly or your lights dim, it’s time to have your battery tested. Rexburg Car Shop can check your battery for free and tell you if it’s time for a replacement before the real cold hits.
2. Keep an Eye on Tire Pressure
Rexburg’s temperature drops can cause your tire pressure to decrease—about 1 PSI for every 10°F change in temperature (U.S. Tire Manufacturers Association). Under-inflated tires wear out faster and reduce your control on icy roads. Check your tire pressure weekly during the winter and fill them to your vehicle’s recommended PSI, which can usually be found on a sticker inside your driver’s side door
3. Top Off Your Fluids
Winter is hard on your car’s fluids—especially antifreeze, oil, and windshield washer fluid. Make sure your coolant has the right mix (typically 50/50 water and antifreeze) to prevent freezing. Use winter-grade oil if your car’s manual recommends it, and switch to a washer fluid designed for freezing temperatures so your wipers don’t freeze mid-drive.
4. Keep a Winter Emergency Kit
You never know when you’ll get stuck in Rexburg snow. Pack an emergency kit that includes a blanket, ice scraper, jumper cables, flashlight, and some snacks. Even a small shovel can help if you need to dig out your tires after a storm.
5. Schedule a Winter Inspection
If you’re not sure where to start, schedule a winter vehicle inspection at Rexburg Car Shop. Our certified technicians can check your battery, tires, fluids, and heating system to make sure your car is ready for the cold. It’s an easy way to stay safe—and warm—this winter.
6. Check Windshield Wipers and Lights
Visibility is everything during Rexburg’s snowy months. Old wipers can smear rather than clear, and dim lights make driving in fog, snow, or early darkness dangerous.
Here’s how to check them:
-
Wipers: Run them with washer fluid—if they leave streaks or make noise, replace them. Most wipers only last 6–12 months.
-
Washer Fluid: Use a winter-grade fluid to prevent freezing.
-
Lights: Turn on your headlights, taillights, brake lights, and turn signals. Check that all bulbs are working and lenses are clean.
Test Your Heater and Defroster Systems
A functioning heater and defroster aren’t just about comfort—they’re critical for safety.
Here’s what to check:
-
Heater: Turn it on and ensure warm air is blowing after the engine has run for a few minutes. Weak airflow may indicate a blocked cabin filter or a failing blower motor.
-
Front and Rear Defrosters: Make sure both defrosters clear condensation and frost quickly. Fogged or frosted windows can seriously reduce visibility.
If you notice poor heating or slow defrosting, schedule a quick HVAC inspection at Rexburg Car Shop before the deep freeze sets in.
