PM checklist

Summer Truck Maintenance Checklist

Summer maintenance focuses on heat stress, tire pressure, cooling capacity, belts, batteries, and driver comfort systems.

If this checklist creates repair items, record them in the maintenance log template and use the PM schedule generator to plan the next due mileage.

Summer Truck Maintenance Checklist
Item What to check Why it matters Notes
Cooling package Inspect radiator, charge-air cooler, fan, belts, hoses, coolant level, and debris blockage. Heat and grades expose weak cooling systems. Investigate repeated fan-on complaints.
Tire heat risk Check pressures cold, tread, sidewalls, valve stems, and dual spacing. Heat increases tire failure exposure. Compare against tire program targets.
A/C and cab comfort Check A/C performance, blower, cabin filter, sleeper HVAC, and belt condition. Driver rest and alertness suffer when cab cooling fails. Schedule before peak heat.
Batteries Inspect batteries, hold-downs, corrosion, and charging system after hot-weather starts. Heat shortens battery life and reveals weak cells. Track jump starts.
Fluids and belts Review coolant, oil, power steering, washer fluid, belt tension, and hose softness. Heat turns marginal rubber and fluids into downtime. Record top-offs.

How Often to Use This Checklist

Use before sustained hot weather and before long high-load routes.

Common Mistakes

  • Checking boxes without writing mileage, unit number, defect notes, and follow-up status.
  • Treating a visual walkaround as a qualified mechanical inspection.
  • Skipping records for small defects that later become repeated repair issues.
  • Filing paper logs where drivers, dispatch, and maintenance cannot retrieve them quickly.

Records to Keep

  • Completed checklist with date, odometer, driver or inspector name, and unit number.
  • Defect correction notes, invoices, parts receipts, and photos when useful.
  • PM due mileage, next inspection target, and any out-of-service decision notes.
