Fall Car Maintenance Tips for Colorado Drivers: 10 Things to Do Before Winter

By Dylan von Kleist

Fall in Colorado can turn quickly.

One week brings changing leaves and clear roads. The next brings overnight freezes, wet pavement, slush, early snow, and road-treatment chemicals. Most drivers know they should check tires, test the battery, and make sure there is a scraper in the car.

Those are important. But the best fall car-prep checklist goes beyond the obvious.

Before winter weather becomes part of the daily forecast, here are the things many drivers overlook, and why taking care of them now can make driving safer, easier, and less expensive later.

1. Check Your Tire Pressure When Temperatures Drop

Most drivers remember to check tire tread before winter. Fewer remember that tire pressure can change as outside temperatures fall.

Lower pressure can affect handling, braking, fuel economy, and tire wear. Colorado State Patrol specifically advises drivers to keep an eye on tire pressure as temperatures decline, while NHTSA recommends using the manufacturer’s recommended pressure found on the driver-side door label or in the owner’s manual, not the maximum pressure printed on the tire itself.

Take five minutes to check all four tires, plus the spare if your vehicle has one. It is a small step that can make a meaningful difference when roads become cold, wet, or slick.

If you have an extra minute, you can watch our video on tire pressure too: https://www.youtube.com/shorts/NKJIJ98v4cQ

Don’t forget:  A tire can look fine and still be underinflated. A quick visual check is not enough.

2. Test Your Washer Fluid Before You Need It

A dirty windshield is more than annoying. It is a visibility and safety issue.

Fall moisture, road spray, dust, and the first snow of the season can leave a thin film on your windshield that becomes much more noticeable when the sun is low. Then winter road treatment, slush, and spray from other vehicles make it worse.

Before temperatures drop, confirm that:

·      Your washer-fluid reservoir is full

·      You are using winter-rated washer fluid with de-icer

·      Your washer nozzles spray evenly

·      Your wipers clear the windshield instead of smearing it

CDOT and NHTSA both include washer fluid, wiper blades, and defroster performance on their winter-preparedness lists.

A useful habit: run the washer system once before you need it. Finding out a nozzle is clogged while driving through slush on I-25 is not ideal.

3. Clean the Inside of Your Windshield, Too!

This is one of the most overlooked fall and winter car-care steps.

A windshield can look clean from the outside and still have a film on the inside from off-gassing materials, fingerprints, interior products, smoke, or normal day-to-day use. That invisible film can create glare when the sun is low, when headlights hit at night, or when moisture builds on the glass.

This is especially useful for early-morning school drop-offs, evening commutes, mountain drives, and any situation where the sun sits low on the horizon.Pro tip: Wipe in different directions to see where the streaks are. Go vertical on the inside and horizontal on the outside. Then, when you spot a streak it is easy to tell what side it’s on

4. Clear the Cowl and Drain Areas Before Leaves Become a Problem

Falling leaves do more than make parking lots look seasonal.

Leaves, pine needles, and debris can collect near the base of the windshield, around the cowl area, and inside drainage channels. If those drains become clogged, water may not move away from the vehicle as designed. That can contribute to unwanted moisture, odors, fogging, or water finding its way into areas where it does not belong.

Before the weather turns, take a quick look:

·      Remove leaves and debris around the windshield wipers

·      Check around the base of the windshield and hood seams

·      Clear leaves from the sunroof track area, if applicable

·      Inspect door jambs and weatherstripping for built-up debris

You don’t need to disassemble anything. Just do not let fall debris pile up for weeks.

5. Lubricate Door Seals Before the First Hard Freeze

There are few worse winter surprises than a frozen door seal when you are already late.

Moisture can collect around door seals, freeze overnight, and make opening a door more difficult. In some cases, forcefully pulling on a frozen door can damage the weatherstripping.

Before snow arrives:

·      Inspect door seals for cracks, tears, or flattened areas

·      Wipe the seals clean

·      Use an automotive-safe rubber protectant or silicone-based conditioner, following the product instructions

·      Pay attention to the hatch or liftgate seal, not just the driver door

This is a small, often-missed maintenance task that can help preserve the rubber and reduce the chance of a frustrating frozen-door morning.

6. Make Sure Your Lights and Cameras Are Doing Their Job

Fall means shorter days, more cloudy weather, earlier sunsets, and more driving in low-light conditions.

Walk around the vehicle and check all the lights; headlights, tail lights, signals, etc. Once you know they light up as they should, wipe down the lenses and consider even applying a spray sealant, wax, or even a coating to keep them clean throughout the winter.

If equipped, don’t forget your backup camera. A thin layer of grime can make the screen much less useful just when visibility is already reduced. If you have a car with multiple cameras check all of them as they are often integrated into collision avoidance, lane departure, and other safety systems. They won’t work if they’re caked up with grime.

7. Wash Off Road Treatment Before It Sits Too Long

This is where regular vehicle care becomes more important than many Colorado drivers realize.

As temperatures fall, CDOT may start to use magnesium chloride and other de-icing treatments before the first snowflake falls. These products help manage icy roads, but residue can build up on your vehicle’s lower panels, wheels, wheel wells, and undercarriage.

Even if you don’t have time for a full wash, a quick stop in our self-serve bays after driving in fall or winter moisture can keep damage in check. Pay particular attention to:

·      Lower doors and rocker panels

·      Wheel wells

·      Wheels and brake areas

·      Front and rear bumpers

·      The undercarriage, where available
