Spring Spring Maintenance Checklist

After winter's cold, salt, and moisture, spring is the time to inspect for damage and prepare for warmer weather and potential road trips.

✓ Spring Inspection Checklist

  • Wash undercarriage to remove winter road salt
  • Inspect tires for winter damage (cracks, bulges, uneven wear)
  • Check and adjust tire pressure (drops in cold weather)
  • Test battery charge — cold weather stresses batteries
  • Replace cabin air filter (traps winter dust and allergens)
  • Inspect wiper blades for winter wear; replace if streaking
  • Check washer fluid level and fill with bug-removing formula
  • Inspect belts and hoses for cracks from temperature cycling
  • Test A/C system before summer heat arrives
  • Check engine air filter — winter slush and debris reduce flow
  • Inspect brake pads and rotors for salt corrosion
  • Check all exterior lights — winter moisture can cause failures
  • Deep-clean interior (winter salt and grime on carpets)
💡 Spring Pro Tip: April is the most popular month for car buying in the US. If you're considering a trade-in, spring maintenance records add real resale value — prospective buyers pay more for a well-documented service history.

Summer Summer Maintenance Checklist

Heat is hard on engines, batteries, and tires. Summer road trips mean more miles, heavier loads, and longer stretches between services.

✓ Summer Inspection Checklist

  • Check coolant level and condition — overheating is the #1 summer breakdown cause
  • Inspect radiator and condenser fins for bugs and debris
  • Test A/C performance and refrigerant pressure
  • Check tire pressure (heat increases pressure — adjust if TPMS light comes on)
  • Inspect tread depth — hot pavement increases stopping distance
  • Check engine oil level and condition — heat accelerates oil breakdown
  • Inspect transmission fluid — towing adds stress
  • Test battery with multimeter (heat + vibration = failure risk)
  • Check serpentine belt tension and condition
  • Inspect fuel cap and evaporative system seals
  • Pack emergency kit: water, jumper cables, first aid, reflective triangles
  • Verify spare tire pressure and jack condition
  • Inspect windshield for chips — thermal expansion causes cracks to spread
💡 Summer Pro Tip: July and August are peak road-tripping months. Before any long trip, do a "T-CLOCK" inspection: Tires & wheels, Controls (brakes, steering), Lights & electrical, Oil & fluids, Chain/belts, Kickstand & chassis. Milepost can track trip-based reminders.

Fall Fall Maintenance Checklist

Fall is the most important maintenance window of the year. Preparing for winter while temperatures are still workable prevents cold-weather breakdowns.

✓ Fall Inspection Checklist

  • Complete brake inspection (pads, rotors, fluid level, lines)
  • Replace wiper blades with winter-rated (beam-style or winter blades)
  • Fill washer fluid with -20°F winter formula
  • Test battery under load — cold cranking amps decrease in winter
  • Clean battery terminals and check for corrosion
  • Inspect and replace coolant if due (check freeze point)
  • Check heater and defroster operation
  • Inspect all rubber seals and weatherstripping
  • Switch to winter tires if you live in snow areas (install below 45°F)
  • Check antifreeze concentration with a hydrometer
  • Inspect exhaust system for leaks (windows will be closed all winter)
  • Lubricate door and trunk hinges and latches
  • Test 4WD or AWD system if equipped
  • Check emergency kit: add blanket, ice scraper, gloves, flashlight
  • Inspect parking brake operation — used more on hills in icy conditions
💡 Fall Pro Tip: October and November are the busiest months for repair shops. Schedule your winter prep by mid-October to avoid the rush. Most shops are booked 1-2 weeks out by November.

Winter Winter Maintenance Checklist

Winter is the most demanding season for your vehicle. Cold starts stress the battery, road salt accelerates corrosion, and reduced traction demands more from brakes and tires.

✓ Winter Monthly Checklist

  • Check tire pressure weekly (drops 1 PSI per 10°F temperature drop)
  • Top off washer fluid — winter slush uses more than you expect
  • Let engine warm 30-60 seconds before driving in extreme cold
  • Clean snow and ice from all lights, sensors, and cameras
  • Avoid parking brake use in freezing rain (pads can freeze to rotors)
  • Wipe door seals with silicone to prevent freezing shut
  • Keep gas tank at least half full to prevent fuel line freezing
  • Check oil level weekly — cold weather increases consumption
  • Inspect for salt damage and wash undercarriage monthly
  • Listen for unusual cold-start noises (weak battery, thick oil, starter strain)
💡 Winter Pro Tip: Dead batteries are the #1 cause of winter breakdowns. If your battery is 3+ years old and cranks slowly when cold, replace it before it leaves you stranded. Milepost can track battery age and send replacement reminders.

Printable Logbook: Track Everything in One Place

Checklists are great for remembering what to inspect, but the real value comes from recording what you actually did and when it's due again. The Milepost printable logbook gives you a compact, dashboard-glovebox format for tracking every service across all your vehicles.

Frequently Asked Questions

What is the most important seasonal maintenance task?

Tire pressure checks. Tires naturally lose 1 PSI per month in warm weather and up to 1 PSI per 10°F temperature drop in cold weather. Under-inflated tires reduce fuel economy, increase wear, and compromise safety. Check monthly and before any long trip.

Do I really need to change my oil every 3,000 miles?

Not necessarily. Most modern vehicles using synthetic oil have recommended intervals of 5,000–7,500 miles. Check your owner's manual. However, severe driving conditions (extreme temperatures, towing, frequent short trips) can reduce this to 3,000–5,000 miles. Track your actual intervals in Milepost rather than guessing.

How do I check my tire tread depth?

Use the penny test: insert a penny into the tread with Lincoln's head pointing down. If you can see the top of his head, your tread is below 2/32" and it's time for new tires. For a more precise measurement, use a tread depth gauge ($5 at any auto parts store).

When should I switch to winter tires?

Install winter tires when temperatures consistently stay below 45°F (7°C). All-season tires harden in cold temperatures and lose traction, even on dry roads. Winter tires use a softer compound that stays flexible in extreme cold. In snow-belt states, aim for late October or early November installation.

How often should I flush my coolant?

Most manufacturers recommend coolant flush every 30,000 miles or 3-5 years. Coolant degrades over time and loses its corrosion-inhibiting properties. Old coolant can cause internal engine corrosion, heater core clogs, and overheating. Check your owner's manual for your specific vehicle.

What's the best way to track vehicle maintenance?

A dedicated app like Milepost is ideal — it logs every service, sets automatic reminders based on mileage or calendar intervals, tracks multiple vehicles, and keeps your history forever. Milepost is free, private, and works offline with no account required.
