Is Your Car Ready for a Hemlock Winter? A Pre-Winter Vehicle Checkup Guide

Dave Murdock • November 15, 2025

Winter in Hemlock, Michigan, is no joke. We get our fair share of snow, ice, and bitter cold temperatures that can push any vehicle to its limits. Getting caught unprepared on Gratiot Road or I-75 during a snow squall isn't just inconvenient—it can be dangerous.


Taking time now to get your car ready for winter can save you from a breakdown, an accident, or a costly repair down the line. This guide will walk you through the key areas to check so you and your family can stay safe on the road all season long.


1. The Power of Your Battery

Cold weather is your car battery’s worst enemy. It reduces the battery’s cranking power, making it much harder to start your engine on a frigid morning. A battery that was just getting by in the fall might fail completely when the first deep freeze hits Saginaw County.


What to check:

  • Age: If your battery is more than three years old, it’s a good idea to have it tested.
  • Corrosion: Look for any white, ashy buildup on the battery terminals.
  • Warning Signs: If your engine is slow to turn over or your headlights dim when you start the car, your battery is struggling.


Our technicians can perform a quick and free battery test to check its health and ensure it has the power to get you through a Hemlock winter.


2. The Visibility Trio: Wiper Blades, Washer Fluid, and Defrosters

You can’t drive safely if you can’t see. Snow, slush, and road salt spray will constantly dirty your windshield, making strong wipers and effective washer fluid essential.


What to check:

  • Wiper Blades: Look for cracks, splits, or streaks. If your blades aren’t clearing the glass effectively, replace them with durable, winter-grade blades.
  • Washer Fluid: Do not use water. Water will freeze in our Michigan temperatures and can damage your fluid reservoir. Fill it with a high-quality, winter-grade washer fluid that is rated for at least -30°F.
  • Defroster: Test both your front and rear defrosters to make sure they are producing strong, hot air. This is critical for clearing frost and fog from your windows.


3. Your Car’s Vital Fluids

Just like you, your car needs the right fluids to perform in the cold. Key fluids can thicken or freeze if they aren’t in good condition or of the correct type.


What to check:

  • Antifreeze/Coolant: This fluid does more than prevent overheating; it also keeps your engine from freezing solid. We can check its strength and condition to ensure it has the proper freeze protection.
  • Oil: Consider switching to a lower-viscosity (thinner) oil for the winter months if your car’s manufacturer recommends it. This helps with cold-weather starting.
  • Brake Fluid: Moisture can contaminate brake fluid over time, which can be a problem in freezing conditions.


4. The Grip on the Road: Tires and Tire Pressure

Your tires are your only connection to the road. When that road is covered in snow or ice, having sufficient tread is non-negotiable.


What to check:

  • Tread Depth: Use the “quarter test.” Insert a quarter into the tread groove with Washington’s head facing down. If you can see the top of his head, your tread is too worn for safe winter driving and you should consider new tires.
  • Tire Pressure: For every 10-degree drop in temperature, your tire pressure drops about 1 PSI. Check your tire pressure regularly, including the spare, as the weather gets colder. Properly inflated tires provide better traction and handling.
  • Tire Type: If you have all-season tires, make sure they have ample tread. For the best safety and performance on our local roads, many Hemlock drivers choose to invest in a dedicated set of winter tires.


5. Stopping Power: A Brake Inspection

Your brakes are your most important safety feature. It takes longer to stop on slick, wet, or icy roads, so having brakes in top condition is critical.


What to check:
Listen for any grinding, squealing, or vibrating when you apply the brakes. If you notice any of these signs, or if your brake pedal feels soft or spongy, you need a professional brake inspection immediately.


6. Preparing for the Unexpected


Even with the best preparation, winter can be unpredictable. It’s always smart to have an emergency kit in your trunk.


Your Winter Emergency Kit Should Include:

  • Ice scraper and snow brush
  • Jumper cables
  • Blanket, gloves, and a warm hat
  • Flashlight with extra batteries
  • First-aid kit
  • Bottled water and non-perishable snacks
  • Bag of sand or kitty litter for traction if you get stuck
