Seasonal Car Maintenance — Spring Checklist

Winter leaves salt on the underbody, wipers glazed from ice scrapers, and tire pressures wrong after every cold snap. A spring once-over catches small problems before the first 500-mile vacation drive — it is maintenance, not a full tune-up.

Work through this list on a dry afternoon with the car cool.

Tires and wheels

• Set all four to cold PSI on the door jamb — see tire pressure guide.
• Look for sidewall cracks from curb hits on ice ruts.
• Schedule rotation if you are past 5,000–7,500 miles since the last one.

Visibility

• Replace wiper blades if they chatter after the first warm rain.
• Fill washer fluid with summer mix; bug season eats fluid on highways.
• Confirm all exterior lights — salt film dims lenses; wipe with soap and water.

Under the hood

• Engine oil level on dipstick — top up with correct viscosity if low; plan change if you are past interval or oil-life %.
• Coolant level in overflow when cold — between MIN and MAX. Do not open a hot pressure cap.
• Brake fluid reservoir — low fluid can mean pads worn or a leak; note level and check again in a week.
• Battery terminals — white corrosion from winter moisture; clean per battery maintenance.

Underbody and brakes (visual)

• Rinse underbody at a touchless car wash if you drove in salted roads — focus on wheel wells, not high-pressure directly at rubber boots.
• Through wheels, glance at rotors — heavy rust lip is normal after sitting; deep scoring or wet fluid on inner wheel is a shop visit.
• Listen for grinding on the first few slow stops after storage — surface rust often squeals once then quiets; continuous grind is not "spring rust."

Cabin

• Replace cabin air filter if you smell stale air when fans run (often 15,000–30,000 mile interval).
• Clear floor drains under mats — wet carpet from melted snow breeds mold.

Fluids and intervals log

Write the date and odometer on your phone notes:

• Oil change due (miles/months)
• Tire rotation due
• Coolant age if you track it (many modern coolants are 5–10 year intervals — read cap label)

Before the long trip

• Spare tire pressure (including temporary spare spec).
• Jump pack or cables in trunk — review jump-start order.
• Know what dash lights mean if one appears on the highway.
