What Should You Check Before a Maryland Winter?
Prioritize the systems most affected by cold temperatures and winter road conditions: tires, battery and charging system, engine coolant, heater and defrosters, wipers and washer fluid, brakes, lights and other essential fluids.
Maryland winters are variable. One week may be mild and the next can bring freezing temperatures, ice or snow. Preparing the vehicle before a storm is much easier than discovering a weak battery, worn wiper blade or low tire pressure on a freezing morning.
Your Maryland Winter Car Checklist
Work through the checklist below before winter weather becomes routine. Tap each item as you complete it.
Cold Weather Changes Tire Pressure
Tire pressure deserves extra attention as temperatures fall. NHTSA notes that tire inflation pressure decreases as outside temperature decreases, which is why a tire that appeared properly inflated during warmer weather may be low on a cold Maryland morning.
Use the recommended pressure shown on the vehicle's tire information label or owner's manual rather than the maximum pressure molded onto the tire sidewall.
Inflation Pressure
Check all tires when cold, including the spare when applicable.
Tread
Look for inadequate tread depth and irregular wear before winter roads become slick.
Damage
Inspect for cuts, punctures, cracks, bulges or other visible damage.
Alignment & Wear
Uneven wear can point to alignment, suspension or inflation issues.
Test the Battery Before the Cold Finds the Weakness
Cold temperatures reduce battery performance while gasoline and diesel engines require more starting power in cold weather. That combination can expose a battery or charging-system problem that was less obvious during summer.
Battery Condition
A battery test can help identify reduced capacity before a no-start morning.
Charging System
Alternator and charging-system performance affect whether the battery stays properly charged.
Connections
Loose, damaged or heavily corroded connections can contribute to starting and charging problems.
Starting Symptoms
Slow cranking, repeated jump starts or intermittent starting deserve attention before temperatures fall further.
Coolant Protects the Engine in Winter Too
Engine coolant is not only about preventing overheating in summer. The cooling system also needs the correct coolant concentration, proper fluid level and leak-free operation as temperatures approach freezing.
Check Coolant Level
Low coolant can indicate a leak or other cooling-system problem that should be diagnosed.
Test Coolant Condition
Coolant should meet the manufacturer's specification and provide appropriate freeze protection.
Inspect Hoses & Connections
Check for leakage, deterioration and cooling-system components that require attention.
Verify Heater Operation
Poor cabin heat can sometimes accompany cooling-system or HVAC problems that should be investigated.
Winter Driving Depends on Seeing Clearly
Snow, road spray, salt, darkness and freezing precipitation can make visibility deteriorate quickly. Your wipers, washer system, defrosters and exterior lights need to work together.
Wiper Blades
Replace blades that streak, chatter, split or fail to clear the windshield consistently.
Washer Fluid
Keep the reservoir filled with fluid suitable for freezing winter temperatures.
Defrosters
Test front and rear defrost functions before you need them during frost, snow or freezing rain.
Exterior Lights
Check headlights, brake lights, turn signals and hazard lights and keep lamp surfaces clear of snow and road grime.
Do Not Enter Slick-Road Season With Brake Problems
Snow and ice already reduce available traction. Existing braking problems can make winter driving more difficult, so unusual brake symptoms should be addressed before poor weather arrives.
Catch Up on Maintenance Before Winter Starts
Pre-winter service is also a good time to review routine maintenance that is approaching due according to your vehicle manufacturer's schedule.
Small Problems Can Become Bigger in Cold Weather
A pre-winter inspection is a useful opportunity to look for damaged hoses, worn belts and fluid leaks that could lead to a breakdown or loss of vehicle function.
Cabin Heat Is Also a Visibility System
The heater is important for comfort, but windshield defrost and defogging are also essential for visibility. Test the HVAC system before the first freezing morning.
Does the Cabin Reach Normal Heat?
Weak or inconsistent heat can justify checking the HVAC and cooling systems.
Does the Windshield Clear?
Confirm the front defroster and rear-window defogger operate correctly before frost and freezing precipitation arrive.
Prepare for the Trip You Did Not Plan
Maryland officials and NHTSA recommend carrying winter emergency supplies in case snow, ice, traffic or a breakdown leaves you delayed.
A Simple Pre-Winter Timeline
Catch Up on Maintenance
Review oil service, manufacturer maintenance, brakes, tire wear, coolant condition and known repair needs.
Perform the Winter Readiness Check
Test the battery, check tire pressure, coolant, wipers, washer fluid, heater, defrosters and lights.
Do the Final Five-Minute Check
Recheck tire pressure, washer fluid and fuel or vehicle charge, pack emergency supplies and review road conditions.
Keep Monitoring the Basics
Continue checking tires, fluids, lights and wipers and address new noises, warning lights or changes in vehicle behavior.
